MP08-20

MANUAL CARTRIDGE VALVE NORMALLY CLOSED, 2-WAY

Overview

Description

The MP08-20X is a 2-way, manual pull to shift, spring return, screw-in, cartridge style directional hydraulic valve.

Operation

In the neutral position the MP08-20X valve blocks flow from port 2 to 1 until it is manually actuated (pulled). When released the valve returns to its neutral position. The bias spring allows up to 180 psi [12,4 bar] back pressure at port 1 before the valve will open.

note: pressure at port 1 will directly act on the spring. Port 1 is intended to be a tank port only.

Features

  • Hardened seat for long life and low leakage.
  • Remains closed to 12.4 bar (180 psi) back-pressure.
  • Compact, industry-common cavity.
