Diaphragm valve BC-72S-H-P

hydraulically-operatedpressure-reducingdouble

Overview
This pilot combines principal functions of a 2-way control circuit with elements of a 3-way control circuit. It is a direct-acting pilot valve actuated by a pressure-responsive diaphragm that balances hydraulic forces against an adjustable spring. A fully balanced trim provides high accuracy and stability. In pressure-reducing circuits the pilot modulates closed as downstream pressure rises above the setpoint. The internal design dynamically varies main valve response speed proportional to the difference between actual and setting pressures.

Features & Benefits

• Integrated dynamic upstream flow restrictor
• Direct-acting, diaphragm-actuated pilot
• Fully balanced trim for accuracy and stability
• Dynamically adjusts main valve response speed proportional to pressure discrepancy
• Modulates closed when downstream pressure exceeds setpoint (suitable for pressure reducing)
• Suitable for differential pressure sensing

Typical Applications

• Pressure reducing valves (e.g. low-pressure irrigation using lay-flat)
• Flow control valves (Differential Pilot: PC-SD-A-P, sealed cover)
• Differential pressure sustaining valves (Differential Pilot: PC-SD-A-P, sealed cover)
