MP10-20

MANUAL CARTRIDGE VALVE NORMALLY CLOSED, 2-WAY

Overview

Description

The MP10-20 is a 2-way, manual pull to open, spring return, screw-in cartridge style, directional hydraulic valve

Operation

In the neutral position the valve blocks flow from ports 2 to 1 until it is manually actuated (pulled). When released the valve returns to its neutral position. Note: pressure at port 1 will directly act on the spring. Port 1 is intended to be a tank port only. The bias spring allows up to 180 psi [12,4 bar] back-pressure at port 1 before the valve will open. A unique 90° rotational lock is optional for positive "open" position holding. The valve resets to spring return-to-close with a 90° turn from the locked-open position

note: pressure at port 1 will directly act on the spring

Features

  • Hardened seat for long life and low leakage.
  • Remains closed to 12.4 bar (180 psi) back-pressure.
  • Optional rotational lock position.
  • Industry-common cavity.
