HEP42-S34 Valve

SYMBOL:
HEV42-S34 Valve symbol

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

OPERATION
The HEV42-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 of the selected
bias spring force.
HEV42-S34 is a vent-to-open directional element.

FEATURES
• Multiple function/application potential.
• Smooth shift transition.
• Low pressure drop.
• All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1.
• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
