A spool-type, screw-in, cartridge-style, hydraulic directional element, with multifunction
potential when used with other directional, pressure, or flow control devices.
The EV20-S34 is a spring-biased blocking valve which will shift to allow full 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. EV20-S34 is a vent-to-open directional valve.
• Multiple function/application potential.
• Smooth shift transition.
• Low pressure drop.
• Industry common cavity.
