DESCRIPTION
A spool-type, screw-in, cartridge-style, hydraulic directional element, with multifunction potential when used with other directional, pressure, or flow control devices.
OPERATION
The EP20-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 value.
EP20-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.
FEATURES
• Multiple function/application potential.
• Low pressure drop.
• Industry common cavity.
