EP08-35

DIRECTIONAL ELEMENT, PILOTED

Overview

Description

The EP08-35 is a screw-in, cartridge style, spool type, hydraulic directional element.

Operation

The EP08-35 is a spring-biased blocking valve, which will open port 1 to 2 when pressure at port 1 exceeds the cumulative pressure at port 3 and the bias spring pressure value. With no pressure at port 3 flow will be allowed from port 1 to 2 once the bias spring force is overcome with pressure at port 1.

Features

  • Multiple function/application potential.
  • Low pressure drop.
  • Compact size.
  • Industry-common cavity.
