EC42-M42

PRIORITY ON DEMAND PRESSURE COMPENSATING ELEMENT WITH STATIC LOAD SENSE

Overview

Description

EC42-M42 is a screw-in, cartridge style, priority on demand pressure compensator with static load sense, intended to provide priority flow in required amount, while allowing excessive flow to be used for auxiliary functions

Operation

With inlet flow at port 3, port 4 will deliver required priority flow regardless of load pressure. Excessive flow exits at port 2. Port 1 is the load sense port. All ports may be fully pressurized

Features

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