PRIORITY ON DEMAND PRESSURE COMPENSATOR WITH STATIC LOAD SENSE

Overview

Description

EC10-42 is a screw-in, cartridge style, priority on demand pressure compensator valve 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, the EC10-42 will deliver required priority flow at port 4 regardless of load pressure. Excessive flow exits at port 2 and port 1 is the load sense port. All ports may be fully pressurized.

Features

  • Priority-on-demand.
  • Static load sense.
  • Hardened parts for long life.
  • Quiet, modulated response.
  • Industry-common cavity.
