The retractable cylinder is mounted on the boiler in a thermal power station to be used in the automatic operation of pushing and drawing oil burners in and out. Thus, it
is a very important pneumatic unit for burner control.
This type of cylinder includes two types; the inner cylinder type consists of the inner cylinder and the outer cooling chamber and insulator, and the outer cylinder type
in which the cylinder is placed in the outer portion.

Features

The insulator wall and the cooling chamber using clean air are placed in the outer portion to prevent cylinder breakage due to
high temperature when the boiler is heated. (inner cylinder type)
The speed controller attached to the cylinder controls the moving time for pushing and drawing the burner in and out.
A locking mechanism is provided to prevent the burner from moving even when it is left for a long time as pushed in.
An explosion-proof switch is appended to take.

Features

● Metal touch system by precision machining and floating performance of the seat offers the perfect sealing construction.
● Maintenance work requires no disassembling of piping.
● Fire-safe construction.
● Double seal construction.
● Shocks under high pressure are prevented with a reduced flow rate in the initial stage of opening the valve, realized by small holes provided in the main port.
● No specific fluid direction.

This valve is the pneumatic explosion-proof, drip-proof solenoid valve controlling pneumatic actuators safely and securely in thermal power stations for
controlling burners, operating valves and driving dampers. The solenoid valve of this type is featured with high reliability brought forth by efforts for durability,
maintainability and easy handling based on Konan’s long-term-cultivated engineering ability added with the latest user needs

Features

Double acting type solenoid valve adopts the solenoid of the magnet latch system. The valve has become drastically smaller than the conventional by concentrating wire lead-out ports in one. (except for some types of 5-port solenoid valves)
4-ports solenoid valve is mounted with a ceramic slide valve as the main valve.
lt is suitable for services of high and low frequency and is highly appreciated in a wide range of applications for its reliability.
The wiring space has been expanded one rank in the terminal box. Products of this type facilitate explosion-proof electrical works which require careful attention to detail.

Konan has incorporated its proper positioner in the pneumatic cylinder to make it possible to set the piston rod stroke position in the cylinder portion arbitrarily
according to the signal pressure setting value. With its unique construction and very compact design, the cylinder of this type is easy to use by working piping only for pressure supply and signal pressure.
The positioner unit has been standardized and can be easily integrated into cylinders of any stroke. It boasts a substantial track record of domestic and international deliveries for driving wind applications. box dampers and burner tilting units

Features

1. The combination of a high-sensitivity diaphragm and a precision spool valve has achieved outstanding stroke precision relative to signal pressure.
2. This cylinder type has demonstrated superb performance for many years, thanks to the efficient, strong, and durable design of all parts.
3. “The cylinder’s air consumption remains minimal when stopped, owing to the use of a precision spool, which ranges from 8 to 14 L/min [ANR] at a supply pressure of 0.5 MPa.
4. Additionally, the built-in special filter with a 2-micrometre filtration grade at the piping port for operating pressure prevents foreign particles from entering the valve and cylinder portions.
5. With a silencer built in at the air discharge ports, its effect keeps a fine working environment.

The booster pumps are small-sized, high-performance piston-type plunger pumps to enable you to obtain high hydraulic pressure easily using pneumatic pressure as a power source.
Pressure drop at the discharge side automatically starts operation and keeps the pressure constant after increasing to the set pressure. These pumps are the most suitable for the power source of press machines, etc.

Features

Small-sized, high-performance power generator to enable you to obtain high hydraulic pressure easily using even commonly available air source
Efficiently integrated respective functions such as cylinder, pump and change valve. Highly efficient long-life structure by simple design
A filter and muffler are built in, which prevents internal components from being damaged and provides quiet work environments with an excellent silence effect.
Because operations are automatically stopped as long as no decrease in pressure (leakage, etc.) occurs on the discharge side when the discharge pressure reaches the predetermined pressure, efficient and economical running is possible.
These pumps apply to any operating fluid such as anti-corrosive fluid, etc. in addition to hydraulic operating oil. (For details, please consult with us separately.)

Employing a sloping flow path for its main body, the Konan sanitary tank valve minimizes fluid accumulation.
As the valve has a tapered structure to prevent protrusion of the valve body into the tank, the rotating propeller can be set close to the bottom of the tank to enable firm stirring of highly viscous solutions.
