DESCRIPTION
A spool-type, screw-in, cartridge-style, hydraulic directional element, with multifunction potential when used with other directional, pressure, or flow control devices.
OPERATION
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 (90-240 psi). The 240 psi spring reequires an extra tall cap.
Note: Orifice discs should not be used with this valve.
FEATURES
• Multiple function/application potential.
• Smooth shift transition.
• Industry common cavity.
