HEP16-S39 Valve

DESCRIPTION
A high-pressure poppet-type, screw-in, cartridge-style, spring-biased, bi-directional blocking-type
hydraulic valve with two built-in checks. When used in conjunction with a small pilot solenoid valve,
the HEP16-S39 is ideal for either high-flow double-blocking circuits or selector circuits. The integral
two-check system prevents leakage, maintaining the pilot signal regardless of the transition or the
work-port pressure changes.

OPERATION
The HEP16-S39 will allow flow from 1 to 2 or 2 to 1 only when 3 is vented to create a pressure drop
across the internal orifice which exceeds the pressure value of the bias spring. When the element is
in the neutral (closed) state, the ratio of areas 1 and 2 is 1:1, and the ratio of areas 1 or 2 to 3 is 1:2.

FEATURES
• Multiple function/application potential.
• Two built-in checks.
• Industry common cavity.
• 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%.
