MANUAL CARTRIDGE VALVE 2 POSITION, 3-WAY

Overview

Description

The MP58-30X is a 3-way, manual pull to shift, spring return, directional hydraulic cartridge valve

Operation

In its neutral position the valve directs flow from port 2 to 1, while blocking port 3. In the actuated (pulled) position it directs flow from port 3 to 2, blocking port 1. The spring chamber is vented at port 1. When released the valve returns to its neutral position. A unique pull and rotate feature for holding the positive actuated position is optional. A 90$ rotation is required to lock the valve in the actuated (pulled) position. The valve resets to spring return (neutral) position with a slight pull and a 90$ turn from the locked actuated position

note: 1. Series operation is prohibited due to the tank port (port 1) pressure rating

note: 2. Pressure at port 1 will directly act on the spool and spring

note: 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.
