EC16-34

PRESSURE COMPENSATING ELEMENT WITH LOAD SENSE U.S. PATENT 7,261,030

Overview

Description

EC16-34 is a screw-in, cartridge style, load sense, pressure compensator with built-in dampening and load holding features. The valve is to be used in combination with a flow control valve for lowering function

Operation

With inlet flow at port 2, the EC16-34 will deliver required flow at port 3 regardless of load pressure at port 2

Features

  • Hardened parts for long life.
  • Hardened seat for low-leakage load-holding capability.
  • Quiet, modulated response.
  • Industry-common cavity.
