Bermad - 3W - Universal "SHARP" Mini Pilot - Model PCP-X-AP and PCP-X-AM

‍

Product code: PCP-X-AP (Plastic version)
Product code: PCP-X-AM (Metal version)

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 pilot can be configured on valves to regulate valves for sustaining or reducing dependent on the plumbing.

‍

‍

Features and Benefits

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

‍

Operation:

The SHARP Mini-pilot sensing chamber is connected to the relevant pressure source according to application.

The SHARP directs control pressure to & from 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

‍

‍

Typical applications

• Pressure Reducing
• Pressure Sustaining
• Pressure Reducing & Sustaining
• Hydraulic relay

Bermad - 3W - Positioning Pilot Valve- Model X

‍

Product code: X

‍

This multi-purpose, direct acting, 3-Way positioning pilot is actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force.

‍

The pilot directs flow and pressure between its ports:

• When sensed pressure is above set point, it connects port “C” to “0”.
• When sensed pressure is equal to set point, it blocks connections between all ports.
• When sensed pressure is below set point, it connects port “C” with “A” and “Z”. An integral needle valve restricts flow through port "Z".

‍

Typical Applications

• Pressure Reducing Valves (Type X) sizes 11/2-10”
• Pressure Sustaining Valves (Type X) sizes 11/2-10”
• Adjustable hydraulic relay (N.O. or N.C.)
• Automatic regulation override (feature 09) sizes 11/2-10”
