Expand All|Collapse All

Overview

Description

EC16-32 is a screw-in, cartridge style, load sense, pressure compensator with static load sense

Operation

With inlet flow at port 2, port 3 will deliver required flow regardless of load pressure sensed at port 1. The valve is intended for use in mineral based or synthetic hydraulic fluids with lubricating properties

Features

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