EV10-S34 Valve

EV10-S34 Valve symbol

A spool-type, screw-in, cartridge-style, hydraulic directional element, with multifunction
potential when used with other directional, pressure, or flow control devices.

The EV10-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. EV10-S34 is a vent-to-open directional valve.

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