Pneumatic Control Valves
PCV - 87
Introduction:
BRI-CON Series 87, Globe type, Double Seated, Top & Bottom -guided, Single Spring & diaphragm actuated, throttling / on-off type Pneumatic Control Valve.
Features:
- Top & Bottom guiding extends range of applications by eliminating the side thrust effect of pressure drop across the plug.
- Double seated design permits control of higher differential pressure and increase valve capacity.
- Air to open or Air to close valve action is obtained by either reversing the body and trim or reversing actuator. Valve body and trim can be easily reversed in the field without additional parts.
- This model can be used in throttling or on-off services to handle air water, steam, gas, oil and other fluids in processes having wide flow range requirement.
