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 HEP42-S39 is ideal for either high-flow double-blocking circuits or selector circuits. The integral two-check system prevents leak-age, maintaining the pilot signal regardless of the transition or the work-port pressure changes.
Product Operation
The HEP42-S39 will allow flow from 1 to 2 or 2 to 1 only when 3 is vented to create a pressure differential 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.
