EV10-S34

DIRECTIONAL ELEMENT, VENTED

Overview

Description

The ev10-s34xx is a screw-in, cartridge style, spool-type, hydraulic directional element

Operation

The ev10-s34xx is a spring-biased blocking valve which will shift to allow flow from 1 to 2 only when port 3 is vented to create a pressure drop across the internal orifice which exceeds the pressure of the bias spring force. EV10-S34 is a vent-to-open directional valve

Features

  • Multiple function/application potential.
  • Low pressure drop.
  • Smooth shift transition.
  • Industry-common cavity.
