EV16-S34 Valve

EV16-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 EV16-S34 is a spring-biased blocking valve which will shift to allow full flow from 1 to 2 only when 3 is vented to create a pressure drop across the internal orifice which exceeds the pressure value of the selected bias spring.
EV16-S34 is a vent-to-open directional valve. It requires a tall cap when specified with bias springs from 6,2 to 16,5 bar (90-160 psi). The 240 psi spring requires an extra tall cap.
Note: Orifice discs should not be used with this valve.

• Multiple function/application potential.
• Smooth shift transition.
• Low pressure drop.
• Tall cap version for higher bias springs 90, 110 and 160 and extra tall cap version
   for bias spring 240.
• Optional manual override only for 40, 90, 110, 160 and 240 psi bias springs.
• Industry common cavity.
