Directional Control Valve Electric Hydraulic Valve 11gpm,12V, SAE Ports 3 Spools Manual Control Valve
Valve controled electrically and by additional lever.
The levers on the spring that helps back to the vertical position
Perfect for machines and vehicles which require the ability to control distributor of two places: electrically from the cabin and levers standing directly on the valve, as for example. HDS-edged and cranes.
Lever three positions
Position the first neutral (lever positioned vertically piston cylinder stands - oil goes to overflow
Position the second working (lever set to slant forward) piston cylinder extends.
Position the third working (lever set to slant backward) piston cylinder retracts.

This a High-Quality Valve and has many outstanding features, including:
- Built-in adjustable relief valve
- High performance,
- High efficiency,
- Compact construction.
- Low-pressure drop.
- Long service life.
- Choice of various ports and circuit valves.
- High accuracy spool is hardened for long term accuracy.
- Manual Override Handles for fine control and emergency operation.
Electro-Hydraulic Control valves eliminate the need for a separate compressed air actuation system.
You Do Not Require the following, Clean dry air, an Air pump, Air tank, Air driers, Pressure regulators, and lubricators to remove moisture, rust, dust, and lubricate the air.
Not to mention and light flexible air tubing that is susceptible to deterioration and damage.
This in turn has the following advantages
- Greatly simplifies and tidy's up the hydraulic system's architecture,
- Speeds up installation and set up and
- Improves reliability and consequently safety.
Principals of operation.
Electro-hydraulic Valves use Solenoid actuated Cartridge Valves to
- divert a small amount of system Oil flow from the actual hydraulic circuit to
- move the flow control spool and
- change the direction of the flow of hydraulic oil
These valves are generally used in Remote Control Applications, such as those found in
- Automotive Tilt Trays,
- Mobile Plant
- Wood Chippers
- Stump Grinders and
- Agricultural equipment.
This model has many more useful applications and can be used to operate up to 3 separate functions that require semi automatic actuation of Valves, Cylinders or Rotating motors.
