EP10-S38 Valve

EP10-S38 Valve symbol

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

The EP10-S38 is a spring-biased poppet valve which will block 1 to 2 or 2 to 1 until pressure
at 1 or 2 exceeds the cumulative pressure at 3 and bias spring. With no pressure at 3, flow will
be allowed from 1 to 2 or 2 to 1 once the bias spring force is overcome with pressure at 1 or 2.
When the element is in 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.

• Multiple function/application potential.
• Low pressure drop.
• Industry-common cavity.
