HEP42-S35 Valve

HEP42-S35 Valve symbol

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.

The HEP42-S35 is a spring-biased blocking valve which will shift to allow full flow from 1 to 2
only when pressure at 1 exceeds the cumulative pressure of 3, plus the bias spring pressure valve.
HEP42-S35 is a pilot-to-close directional valve.
With no pressure at 3, flow will be allowed from 1 to 2 once the bias spring force is overcome with
pressure at 1.

• Multiple function/application potential.
• 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%.
