EC50-30

FLOW ON DEMAND PRESSURE COMPENSATING ELEMENT WITH STATIC LOAD SENSE

Overview

Description

EC50-30 is a screw-in, pressure compensating element intended for use with remote fixed or variable orifices to yield a two-port type, pressure compensated flow regulating valve for use in high pressure circuits

Operation

EC50-30 valve maintains a constant flow rate from port 2 regardless of load pressure changes in the circuit downstream of port 2. The valve maintains a constant differential pressure from circuit point P to port 3 (see symbol), thereby regulating hydraulic flow rate between the two points in the circuit

Features

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