EP16-S35

DIRECTIONAL ELEMENT, PILOTED

Overview

Description

The ep16-s35xxx is a screw-in, cartridge style, pilot to close hydraulic directional element.

Operation

The valve is a spring-biased blocking valve which will shift to allow full flow from port 1 to 2 only when the pressure at port 1 exceeds the cumulative pressure of port 3, plus the bias spring pressure value.

Features

  • Multiple function/application potential.
  • Low pressure drop.
  • Industry common cavity.
  • Manual override available with 90, 110, 160, and 240 psi bias springs.
