Operating Instructions

1. Fluid

● Use only with clean fluids as dirt, wastes, etc. in the fluid may cause malfunctioning.

2. Caution

● A pressure detection valve is a bleed-type valve. During operation, air escapes from the bleeding hole, but this does not affect the valve performance.

3. Pressure setting

Step 1: Supply a signal pressure equal to the set pressure（Valve opens）.

Step 2: Turn the adjusting screw clockwise to close the valve and complete the pressure setting. （After the pressure setting is completed, a small amount of air will escape from the bleeding hole. However, this does not affect the valve performance.）

Step 3: Increase the signal pressure. （Set the signal pressure at least 0.05 MPa higher than the set pressure for stable valve operation.）

This valve prevents accidents that may arise from a cylinder suddenly rising in response to the operation of a solenoid valve, etc. It has a built-in bleed mechanism to supply air to the cylinder gradually at the initial stage of operation of the cylinder, and by automatically opening the main valve at high speed when the pressure in the cylinder rises enough.

Operation

Standard type

When the cylinder has an internal pressure of 0 MPa: See circuit. When the three-position, open-center solenoid valve is placed in neutral and the directional control valve is OFF, the air pressures in chambers and of the cylinder are discharged through the solenoid valve, and the air pressure in the area flows to and is discharged. During discharge, the main valve of the slow-start valve is kept closed by spring force

To start the cylinder, activate the directional control valve by energizing solenoid number 2 to move the piston right. The air pressure then flows through passage 111, the drilled passage in the slow start valve’s piston, and finally into the cylinder chamber, increasing gradually. Install a needle valve between the chambers to adjust the air flow to the cylinder chamber, metering the cylinder’s control. This feature prevents the sudden operation of the cylinder. At the startup of the cylinder, the pressure on the piston top is still small, and hence the main valve of the slow start valve remains closed, as in the circuit.

During normal operation of the cylinder: Air enters the cylinder chamber through passages, and gradually increases. When the pressure reaches a given value, it starts to act on the piston top, pushing the piston down, and fully opens the main valve of the slow-start valve. When the main valve is opened, the normal air pressure circuit is completed. With a speed controller installed as the meter-out device, the cylinder speed can now be controlled.

Operation

Signal pressure ❶ enters diaphragm chamber B ❷ and acts on diaphragm B ❸. When the signal pressure exceeds the spring force, it pushes diaphragm B upwards and causes ball ❹ to close the discharge hole ❻ in the diaphragm retainer ❺. At the same time, the signal pressure flows between diaphragm retainer ❺ and O ring ❼ to diaphragm chamber A ❽. It acts on diaphragm A （❾） and forces valve （⓫）open against the force of spring A （❿）, thus completing the operating circuitIf the signal pressure falls below the spring’s force, the spring pushes diaphragm B down, opening discharge hole in the diaphragm retainer and linking diaphragm chambers B and A. This action discharges the signal pressure from diaphragm chamber A through the discharge hole. Once emptied, spring A’s force closes the valve, sealing the operating circuit and preserving the circuit’s pressure. In the two-circuit type (LVD5-02), circuits 1 and 2 run in parallel, with their respective diaphragm chambers A interconnected.

Operating Instructions

1. Fluid

● Use only with clean fluids as dirt, wastes, etc. in the fluid may cause malfunctioning.

2. During operation

● Lockup valves are of the bleed type. Although a small amount of air will escape from the relief opening during operation, it will not cause any problems under normal use. To prevent air from escaping, apply a signal pressure more than 0.15MPa higher than the set pressure on the valve.

3. Pressure setting procedure 

Step 1: Apply a signal pressure equal to the set pressure.（Valve opens.）

Step 2: Turn the adjusting screw clockwise to close the valve. This completes the pressure setting. （After the pressure setting is completed, a small amount of air will escape from the relief opening. However, this will not cause any problems under normal use.）

Step 3: Increase the signal pressure. （ Applying a signal pressure more than 0.05MPa higher than the set pressure will make operation more stable. To prevent air from escaping, apply a signal pressure more than 0.15MPa higher than the set pressure.）

Operation

When you shift a three-position, open-center type directional control valve upstream of the safety block valve to deliver air through port MA or MB, air pressure moves the valve’s disc and piston left or right against spring force. This connects ports MA with CA or MB with CB, raising or lowering the cylinder. Shifting the control valves to neutral releases air pressure from port MA or MB, and the spring forces the disc to seal the opening. With the poppet type, the discs ensure no air leakage, holding the cylinder securely in the middle position for extended periods.

Model Code

Specifications

● Noise reduction is defined as the difference between the noise that occurs at the orifice when fluid with max. flow rate is applied at 0.5MPa and that occurs when the exhaust filter is mounted to the orifice（noise measured at 1m away from the noise source）.

Outside Dimensions

Application Example

KMFC2 exhaust filter collects oil mist in compressed air exhaust from actuators and valves, while at the same time cuts off exhaust noise.
As seen in the figure, a centralized exhaust system enhances the efficient dual function of the filter.

Flow characteristics graphs

● When KMFC2-20A is used at 1600 L/min, back pressure is 0.05MPa.

Model Selection Chart

Guidance for selection 

The type of exhaust filter is determined based on the air consumption of the applicable circuit.
① Calculate the air consumption of an actuator that works with the filter. If the port volume between the switch valve and the actuator is large, add the volume to the calculated value.
② Multiply the calculated value 1.4-fold and select an exhaust filter that functions with a higher flow rate than the multiplied value. Refer to the 1.4-fold air consumption values of a Pneumatic cylinder left for a selection of the exhaust filter. Please use it for model selection.

Example of calculation 

Conditions:

Working pressure ：0.5MPa（gage pressure）
Bore size of cylinder：φ180
Piston speed　　　：450㎜ /s

Air consumption of cylinder:

● As result, KMFC2-40A（Nax flow 6400L/min）is selected.

1. Installation 

● Clean the piping.

Flash the piping thoroughly after laying. Use pipes with an inside surface plated with zinc.

● Fluid.

Since dirt and wastes in the fluid hinder proper functioning of the valve and shorten its service life, use clean air as the fluid.

● Do not force port.

Lirnit the number of pipe threads screwed into the valve to four or five for any of sizes 8A to 25A（Rc1/4“to 1”）.  If the pipe is forced to enter the valve beyond that point, the valve body may be cracked, and leakage or malfunctioning result.

● If valves other than the type with a lock mechanism are to be installed and used vertically, please contact us.

2. Before use 

● Conversion to a threeport valve.

If either of the two OUT ports is plugged, the valve can be used as a three-way, directional control valve.

● Leakage from the disc.

Since a disc is fitted in the valve, a small amount of leakage may occur due to deformation at installation or from long periods of use, etc. However, this will cause no problem in normal use of the valve.

Operation

Standard type 

❶ Deflector

● Turns air from the primary side into a rotating air flow and separates moisture from the air by centrifugation.

❷ Filter element 

● Finally filters out lightweight dirt and dust,foreign particles, etc.that cannot be separated from the air by certrifugation.

❸ Bowl 

● The drain separated by centrifugation runs down the internal wall of the bowl and collects at the bottom.

❹ Baffle plate

● Prevents the drain in the bowl from re-entering the air.

❺ Diaphragm chamber 

● Air pressure from the primary side enters the diaphragm chamber at the same time that it does the secondary side through the filter. The diaphragm is forced up until the pressure in the diaphragm chamber is equal to th spring force. The valve is then closed.
● As the pressure in the secondary side drops, the valve is opened and the primary-side air pressure is furnished to the secondary side again.

❻ Relief valve 

● When the handle is turned counterclockwaise to lower the set pressure, the spring force weakens compared with the pressure in the diaphragm chamber. This forces the diaphragm up and opens the relief valve,thus releasing the air pressure in the secondary side to the atmosphere until that pressure is equal to the spring force.

❼ Handle（adjusting screw） 

● To lower the set pressure,turn the handle counterclockwise.
● Turning the handle clockwise causes the adjusting screw tip to force the spring retainer down,thus compressing the spring. This opens the valve, and the air pressure entering the primary side flows to the secondary side.

❽ Side glass

The lubricator is intended for mist-lubrication of controls and peripheral equipment in pneumatic lines, as required, by automatically sending oil in mist from the pneumatic line. This extends the service life of the components in the pneumatic line and improves their efficiency.

Model Code

Specifications

Operation

❶ Check valve 

Part of the air entering the IN port passes through the check valve and pressurizes the oil in the bowl. When the oil is added（filter plug removed）with the oil under pressure, the ball of the check valve is forced against the seat, and the air is prevented from entering the bowl. In practice, however, the check valve is not closed completely, and a very small amount of air continues to enter the bowl. This does not hinder lubrication.

❷ Siphon tube 

A pressure differential in the sight glass causes oil to pass through the siphon tube to the adjusting screw section.

❸ Oil spray section 

Here, oil droplets turn into minute mist particles and are diffused in the air.

❹ Sight glass 

As pneumatic pressure enters the IN port, a pressure differential results in the sight glass. The oil sent there through the siphon tube falls in the form of droplets through the drip tube.

❺ Oil quantity adjustment

Model Code

Features

High precision 

● Outstanding input/output precision assures significantly low hysteresis at pressure rise/down.

Large fluid amplification factor 

● Even minimal change in signal pressure can produce a large fluid rate.

Large relief flow 

● With its large relief flow volume.VB7 is suitable for tension control.

Minimal cracking pressure 

● Minimal cracking pressure with a flow rate at around 0L/min allows rapid response to slight pressure change.

Slight pressure fluctuation 

● Outstanding pressure characteristics minimize the effect of the primary pressure change on the secondary pressure.

By-path system 

● A built-in needle valve reduces electrode hunting that may occur on the electric circuit.

Specifications

For use below 5℃, provide adequate measures against freezing.
Make sure to produce at least 0.1MPa of the pressure difference between primary and secondary sides of the pressure port, or an appropriate flow rate cannot be achieved.
Minimal leakage may occur due to the diaphragm performance characteristics. This does not have any problem with the function.

Characteristics

Operation

❶ Diaphragm“B” 

Signal pressure acts on diaphragm B to open the valve.

❷ Diaphragm“A”

The secondary pressure acts on diaphragm A against signal pressure. When the secondary pressure is lower than the signal pressure, diaphragm A is forced down and the valve opens. When both pressures are equal, the valve closes. When the secondary pressure is higher than the signal pressure, the relief valve opens and releases the secondary pressure until the secondary pressure is equal to the signal pressure.

❸ Needle valve 

When the needle valve is opened, the secondary side is connected to the signal pressure side. This mechanism maintains safe and stable operating conditions

The volume booster actively maintains pressure in air tanks and actuators, delivering high performance for quick pressure relief. You can operate it remotely through a pilot-operated regulator placed at a convenient nearby location.

Model Code

Specifications

● For use below 5℃, provide adequate measures against freezing.
● Make sure that the primary pressure is at least 0.1MPa higher than the secondary pressure.

Characteristics

Operation

① Signal pressure enters from the pilot port （P） t to the upper diaphragm room and acts on the diaphragm to open the main valve.

② The primary pressure flows through the main valve to the secondary side and increases the secondary pressure while entering through passage A to the lower diaphragm room and acts on the diaphragm.

③ When the secondary pressure and the signal pressure are equal, the main valve closes to hold the secondary pressure.

④If the secondary pressure exceeds the signal pressure, it pushes the diaphragm up, opening the relief valve. This releases the secondary pressure through the relief port (R) until it equalizes with the signal pressure.

⑤ The needle valve is used as a by-path between the signal pressure side and the primary side. When strained （turned clockwise）, the response of the secondary pressure to the signal pressure becomes faster. When the needle valve is open （turned counterclockwise）, the response becomes slower. Adjust the needle valve to obtain stable operation of the regulator.

Regulators are used to reduce the pressure of the compressed air from the compressor so that air is automatically fed at constant pressure to the pneumatic line.

Model Code

Specification

Operation

Standard type 

❶ Diaphragm chamber
● Air pressure enters the diaphragm chamber as it passes from the primary to the secondary side. The diaphragm is raised until the pressure in the chamber is equal to the force of the spring. The valve is then closed.
● If the pressure on the secondary side drops, the valve is opened, and air is fed from the primary to the secondary side.

❷ Relief valve
● When the handle is turned counterclockwise to lower the pressure setting, the spring becomes weaker than the pressure in the diaphragm. Thus, the diaphragm is raised, the relief valve opened, and the air in the secondary side is released to the atmosphere until the pressure is equal to the force of the spring.

❸ Handle （adjusting screw）
● To lower the pressure setting, turn the handle counterclockwise.
● As the handle is turned clockwise, the tip of the adjusting screw forces down the spring retainer, compressing the spring. The valve is opened, and air is fed from the primary to the secondary side.

An automatic drain has been fitted to the air filters. This separates and removes the drain from the pneumatic line, thus preventing trouble.

Model Code

Specification

● The above values of mass exclude the weight of the mounting bracket.
● For specifications other than those listed above, please contact us.

Operation

❶ If sufficient drain fluid, separated out by the filter, collects in the float case, the inner and outer floats rise under the buoyancy of the drain.

❷ The inner float pushes up the piston while the outer float presses the outer ring of the piston and the seal on the lower part of the upper lid. Thus, airflow between chambers A and B is shut off.

❸ As air is consumed in this condition,a pressure differential occurs between chambers A and B. If the differential rises above 10％, the piston rises further, and the bottom valve is opened, allowing drain fluid to discharge. After drainage, the pressures in chambers A and B equalizes, and the piston descends, closing the bottom valve.

❹ Therefore, if the air is consumed intermittently under the control of a solenoid valve, the air filter works well. Below an operating air pressure of 0.05MPa, the upward forces from the buoyancy of both floats automatically cause the piston to rise, the bottom valve to open, and the drain to be discharged, whether or not there is a pressure difference present between the chambers. Pressing the pushbutton for manual discharge opens the bottom valve and causes the drain to be discharged, regardless of the operating air pressure.
