Stellar Industries 50914 Parker 4-Way Tandem-Center Solenoid Valve

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 50914 Solenoid Valve is a Parker three-position, four-way directional cartridge valve identified as model DSH12557DNN. Its tandem-center spool connects pressure flow to the tank in neutral while blocking both actuator ports to help hold the controlled function in position.

This high-flow valve is rated for up to 15 GPM and controls double-acting hydraulic cylinders or bidirectional motors. Replacing a worn or sticking valve helps restore responsive movement, proper load holding, and dependable control in both operating directions.

What This Part Is Used For

The Stellar 50914 valve directs hydraulic oil to operate a compatible function in two directions. In the neutral position, pump flow returns to the reservoir while the work ports remain blocked. Energizing either side shifts the spool to extend or retract a cylinder or reverse a hydraulic motor.

Common Reasons For Replacement

Hydraulic function does not move
Function operates in only one direction
Valve spool sticks or shifts slowly
Controlled function drifts in neutral
Valve produces excessive internal leakage
Hydraulic oil leaks around the cartridge
Manual override no longer operates correctly
Solenoid or valve fails to respond to electrical commands
