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. The tall cap is also
  required when the valve is specified with manual overide and the 40 size bias
  spring. Extra tall cap version for bias spring 240.
• Optional manual override only for 40, 90, 110, 160 and 240 psi bias springs.
• "G" metering option for metered flow control when opening.
• Industry common cavity.
