EP12-S35 Piloted Spool-Type Logic Element (EP12-S35)
A spool-type, screw-in, cartridge-style, hydraulic directional element, with multi-function potential when used with other directional, pressure, or flow control devices.
Product Operation
The EP12-S35 is a spring-biased blocking valve which will shift to allow full flow from ➀ to ➁ only when pressure at ➀ exceeds the cumulative pressure of ➂, plus the bias spring pressure value.
EP10-S35 is a pilot-to-close directional valve.
With no pressure at ➂, flow will be allowed from ➀ to ➁ once the bias spring force is overcome with pressure at ➀
Product Features
• Multiple function/application potential.
• Low pressure drop.
• Industry common cavity.
• Manual override option available with 80 psi spring only.
