DIRECTIONAL LOGIC ELEMENT PILOT TO CLOSE, INTERNALLY DAMPED

Overview

Description

The EP10-S36X is a screw-in, cartridge style, pilot to close, internally damped, hydraulic directional logic element.

Operation

The valve is a spring-biased blocking valve which will shift to allow full flow from port 1 to 2 only when the pressure at port 1 exceeds the cumulative pressure of port 3 plus the bias spring pressure value. Port 1 is internally connected to port 3 through a damping chamber which allows annular leakage flow to port 3.

Features

  • Internally damped for improved stability
  • Staggered hole cage for improved resolution
  • Chrome silicon springs offer consistent performance at high temperatures
  • Use as a pressure control or compensating element
