Power off (during power outage) return type ball valve operator MCP Series
MCP-03 type “Two-wire operation type”

MCP-03 type:
A built-in electric double layer capacitor allows the two-wire operating device to open and close by simply turning the power on and off.

Specification

Features

The VB-2326 series 2-way solenoid valve is designed for opening and closing flow paths for non-corrosive water, oil, air, non-corrosive gases, and saturated steam.

In particular, this series has a separate structure that minimizes the influence of fluid temperature on the electromagnetic operating section, making it most suitable for high-temperature fluids below 180℃.

Additionally, a yoke separates the valve body from the electromagnetic section, enabling the creation of valves with custom signal switches or manual levers.

By standardizing the valve body material to stainless steel (custom-made), it becomes suitable for special chemical solutions and food-related applications.

Products other than 100A can operate up to a maximum pressure difference of 0.7MPa, so they have a wide range of use and are used for fluids other than room temperature.

A strong spring inside the iron core opens the valve when not energized, while magnetic force exceeding this spring closes the valve. However, due to a small margin, it’s unsuitable for back pressure environments.

The electromagnetic operation part is a DC electromagnetic type with continuous rating class B insulation, so you can rest assured that even if trouble occurs with valve operation, there will be little chance of coil burnout.

In addition, we have a surge suppressor and rectifier built into the terminal box, so we can manufacture it for either AC or DC.

The valve is directly connected to the electromagnet, so it operates reliably even without pressure.

Specification

Features

The VB-2325 series 2-way solenoid valve opens and closes flow paths for non-corrosive water, oil, air, non-corrosive gases, and saturated steam.

This series features a design that minimizes fluid temperature impact on the electromagnetic section, making it ideal for high-temperature fluids up to 180℃.

A yoke isolates the valve body from the electromagnetic section, enabling the design of valves with custom signal switches or manual levers.

Furthermore, standardizing the valve body material to stainless steel (custom-made) allows its use for special chemical solutions and food-related applications.

Products other than 100A can operate up to a maximum pressure difference of 0.7MPa, so they have a wide range of use and are used for fluids other than room temperature.

A spring in the iron core ensures closure when off but weakens to reduce magnetic force loss when on, unsuitable for reverse pressure scenarios.

The DC electromagnetic operation unit features continuous Class B insulation, ensuring low risk of coil burnout even in valve malfunctions.

In addition, we have a surge suppressor and rectifier built into the terminal box, so we can manufacture it for either AC or DC.

The valve directly connects to the electromagnet, ensuring reliable operation even in the absence of pressure.

Specification

Features

The VB-2324 series 2-way solenoid valve is designed for opening and closing flow paths for non-corrosive water, oil, air, non-corrosive gases, and saturated steam.

All models other than 100A can operate up to a maximum pressure difference of 1MPa, so they have a wide range of applications and are the most commonly used series.

A strong spring opens the valve when off; magnetic force closes it with little margin, unsuitable for back pressure areas.

In addition, we have a surge suppressor and rectifier unit built into the terminal box, so we can manufacture it for either AC or DC.

The valve is directly connected to the electromagnet, so it operates reliably even without pressure.

A compact, lightweight, high-output control rack-type electric operating machine.
The rack-type electric actuator is a linear output shaft type of our control motor (electric actuator), which has a proven track record of high reliability in various process controls, and is an excellent controller for electric valves. This is a product.

(1) High output

Improved durability has more than doubled the thrust.
Furthermore, the maximum thrust is 1.5 times the rated thrust, ensuring a margin for closing and closing the valve.

(2) Linearity

Linearity is now ±1%.
By integrating the valve and operating device, it can be combined with an electric positioner or balancing relay to provide highly accurate control that corresponds to the output of various controllers.
Figure 1 shows the actual movement measurement data of the thrust shaft for an input of 4 to 20 mA for a rack-type electric actuator with a built-in electronic positioner.

(3) Compact and lightweight

Since it has a high rated output compared to the size of the actuator, when combined with our electric valve, you can select an actuator with up to 1/4 of the rotational torque of conventional valves, making it a product with high cost performance.

(4) High reliability

By repeatedly conducting durability tests under the conditions of applying the rated thrust load over the entire full stroke range and increasing the strength of the rack and pinion structure, we are now able to bring out the control motor’s durability to its limits.
Our control motors have a proven track record of high reliability as actuators for various process controls, and we have confirmed that they have the same level of durability as rack-type electric actuators for electric valves.

Specification

The structure, shape, material, etc. of the seal are important for the performance of a sealed damper. We have carefully considered these issues and adopted the standard structure shown in Figure 3.
Sealing improves in the order of metal → soft → ring seal. Consider airtightness and fluid properties when making a selection.

As shown in Table 1, the louver type has a steep rise, so a small opening can produce a large flow rate. In addition, the butterfly type has a wider control range and better controllability.

Table 2 shows a rough evaluation of the features, so please refer to it when making a selection.

Table 1 Flow characteristics

Table 2 Damper evaluation

Shaft sealing method

The standard structure is shown below.

Standard damper

There are two types of commonly used dampers: butterfly and louver types.

Since the butterfly type has a single wing, the structure is simple and a round shape is best, but the wing may protrude a lot.

The louver type has multiple blades and has a rectifying effect, but it lacks airtightness.

Hopper damper

It processes the powder quantitatively while keeping it airtight. The simple structure makes it easy to inspect for wear and adhesion, and to easily disassemble and replace parts.

In addition, the double hopper type, which is arranged one above the other, allows powder to fall by alternately opening and closing the upper and lower blades, enabling continuous quantitative discharge and preventing powder from scattering due to pressure differences during discharge.

• The blades are pressed against the damper seat and stopped by torque detection to prevent leakage.
• No need to adjust the fully closed position of the damper
• With clutchless manual handle
• External dimensions are the same as MCHT-10, 20, 40
