Servo Pilot Valve, Metal Model PC-S-M

This pilot combines all 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, which seeks to reach equilibrium between hydraulic and set spring forces. A fully balanced trim ensures high accuracy and stability. When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises above setting. The pilot’s unique internal design dynamically increases and decreases the main valve response speed in direct proportion to the discrepancy between actual demand and pilot setting pressures.

Paddle Flow Rate Servo Pilot Model PC-70-M

This flow rate pilot combines all 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 paddle that is positioned within the flow stream. Should demand rise above setting, the increasing flow dynamic force moves the paddle, which thereby pushes the pilot trim against the spring force. This increases control water flow into the control chamber, causing the main valve to throttle closed limiting system flow to pilot setting. The pilot’s unique internal design dynamically increases and decreases the main valve response speed in direct proportion to the discrepancy between actual and setting flow rate.

Pressure Sustaining Pilot Valve, Metal Model PC-30-M

This is a 2-way direct acting pilot valve, actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. When used in a pressure relief/sustaining circuit, the pilot modulates open as upstream pressure rises above set point.

PC-SHARP-X

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.

Quick Pressure Relief Pilot Valve, Plastic Model PC-3Q-P

This pilot integrates all principal functions of a 2-Way control circuit in a single assembly. It is a direct acting pilot valve, actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. The pilot opens at upstream pressure rise above set point. An integral restriction acts as an upstream flow restrictor smoothing valve closing and simplifying the control circuit.

Positioning 3-Way Pilot Valve, Metal Model PC-X-M

This multi purpose, direct acting 3-way positioning pilot Valve is actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. The pilot directs flow and pressure between its ports:

  • When sensed pressure is above set point, it connects port “0” to “3”.
  • When sensed pressure is equal to set point, it blocks connections between all ports.
  • When sensed pressure is below set point, it connects port “3” with “2”.

Relevant pressure is continuously sensed through port “1”.
