MANUAL CARTRIDGE VALVE 2 POSITION, 3-WAY

Overview

Description

The MP08-34X is a 3-way, manual pull to shift, spring return, directional hydraulic cartridge valve

Operation

In its neutral position the valve blocks flow between ports 2 and 3. In the actuated (pulled) position, it allows flow between ports 2 and 3. The spring chamber is vented at port 1. When released, the valve returns to its neutral position

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

Features

  • Hardened spool and cage for long life.
  • Pressure to 14 bar (200 psi) on port 1.
  • Optional rotational lock position.
  • Compact, industry-common cavity.
