EC10-32

FLOW ON DEMAND PRESSURE COMPENSATING ELEMENT WITH STATIC LOAD SENSE

Overview

Description

The EC10-32 is a screw-in, cartridge style, load sense, flow on demand, pressure compensator

Operation

With inlet flow at port 2, port 3 will deliver required flow regardless of load pressure sensed at port 1. 0.021 in [0,53 mm] orifice is recommended to be installed in load sense line at port 1 for better stability

Features

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