DESCRIPTION
A high-pressure spool-type, screw-in, cartridge-style, hydraulic directional element,
with multi-function potential when used with other directional, pressure, or f ow control
devices.
OPERATION
The HEV16-S34 is a spring-biased blocking valve which will shift to allow full f ow from
➀ to ➁ only when ➂ is vented to create a pressure drop across the internal orif ce
which exceeds the pressure of the selected bias spring.
HEV16-S34 is a vent-to-open directional valve.
FEATURES
• Multiple function/application potential.
• Smooth shift transition.
• Low pressure drop.
• All HyPerformance products are tested to the rigorous standards
of the NFPA specif cation T2.6.1.
• All HyPerformance valves are tested at a verif cation level of 90%
and an assurance of 99%.
