PRESSURE COMPENSATOR

Overview

Description

This valve is a pressure - compensating element,intended for use with remote fixed or variable orifice to yield a two - port type, pressure compensated, flow - regulating hydraulic valve

Operation

This valve maintains a constant flow rate from port 2 regardless of load pressure changes in the circuit downstream of port 2. This valve maintains a constant differential pressure from circuit point P to port 3 (see symbol), thereby regulating the hydraulic flow rate between the two points in the circuit

Features

  • Hardened parts for long life.
  • Quiet, modulated response.
  • Industry-common cavity.
