In this catalogue, you will find all datasheet for Pneumatic single seat control valve, including material, dimension, assembly drawing, working temperature, pressure rating, nominal size, etc

The action of the pneumatic single-seat control valve is realized by receiving the signal through the positioner, inputting the compressed air into the pneumatic actuator to generate thrust, and pushing the valve core through the connecting rod to generate the corresponding displacement, that is, the so-called stroke. The flow cross-sectional area changes, so as to achieve the purpose of adjusting the flow, pressure and temperature of the medium. .

Structural features

1. The pneumatic single-seat control valve adopts the top guide structure, the valve body has a compact structure, the fluid channel is S streamlined, the pressure drop loss is small, the flow rate is large, the adjustable range is wide, and the flow characteristic accuracy is high;

2. The spool form of the single-seat valve is an upper-guided plunger valve. The guiding area of the spool guiding part is large, and it has the characteristics of strong anti-vibration performance.

3. The compression spring adopts the form of multiple combinations to reduce the height and finely process the guide surface of the push rod, improve the hardness and reduce the roughness, so as to reduce the return difference and increase the sealing effect;
