I added a ripper to my 1950 Allis Chalmers HD5G. The valve I had before I bought this one did not bypass and blew my main hose apart.
I have been using this vave for over a year now and it works great.
It is exactly what I needed and added to my existing valves without a issue.

About this item
Description


1 coil 21 GPM hydraulic directional control valve
Our hydraulic spool valve was specifically designed for use in mobile hydraulic applications. It is compact and has a flow capacity of 21 GPM at 4300 psi. This valve offers an alternative to currently available monoblock valves. It comes standard with an adjustable pressure relief valve and levers.
- Hydraulic slide valve
- Automatic reset
- Great internal valve
- Compact structure

Hydraulic charging valve
This hydraulic directional control valve controls and directs the flow of hydraulic oil between hydraulic pumps and hydraulic cylinders, motors, tanks, etc.

Neutral spring center
The spring-loaded coil can be returned to the neutral position, and the spring makes operating the joystick easier.

Internal check/pressure relief valve
The check valve and overflow valve of the valve body can help you to perform your work better and more safely.

Structure with high tensile strength
The robust iron construction, the precision grinding and the stable, chrome-plated coils ensure a long service life.

Compact handle design
The control handle is easy to use and has a spring on the underside that returns the handle to the neutral position.

Wide application
Ideal for forklifts, small industrial machines, small agricultural machines, small hydraulic presses, punching machines and other processing equipment.
