EP10-S35

DIRECTIONAL ELEMENT, PILOTED

Overview

Description

The ep10-s35xx 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.
  • Range of bias spring pressure options. Tall cap required for 160, M11, 230, and M15.9 spring options.
  • Industry-common cavity.
