Bermad - Model PC Sharp X - Plastic and Brass - 3 Way Universal SHARP Pilot

SHARP is the most sensitive and accurate mini-pilot in the market. It is a multi-purpose 3-Way mini-pilot, diaphragm-operated, based on a balance between the hydraulic force acting on the diaphragm, and the mechanical force of the calibration spring. The SHARP replaces the PC-X mini-pilot through all applications range.

Features and Benefits

• Universal Mini-Pilot: Serves as a pressure-reducing pilot, pressure-sustaining pilot, flow control Pilot [PC-XD] & hydraulic relay.
• Easy fit-in: Connections are identical to PC-X & Servo (PC-S)mini-pilots, allowing easy & simple on-site upgrades.
• High Quality: All calibration springs are made of Stainless Steel
• Accurate & Flexible: Pressure setting range:0.5-10 bar; 8-145psi. Tolerance: < 2m; 3psi

Typical Applications

• Pressure Reducing
• Pressure Sustaining
• Pressure Reducing & Sustaining
• Flow Control (with Sealed Cover "D")
• Hydraulic Relay

Operation

The SHARP Mini-Pilot sensing chamber is connected to the relevant pressure source according to application. The SHARP directs control pressure to & from the valve control chamber, by opening and closing water passages: The SHARP Mini-Pilot sensing chamber is connected to the relevant pressure source according to application. The SHARP directs control pressure to & from the valve control chamber, by opening and closing water passages:

• When sensed pressure higher than setting: 0 <->3
• When sensed pressure equal to setting: 2| <->|3|<-> |0 “locked”
• When sensed pressure lower than setting: 2<-> 3
