Stellar Industries 50915 Parker 4-Way Open-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 50915 Solenoid Valve is a Parker three-position, four-way directional cartridge valve identified as model DSH12559DNN. Its open-center spool configuration allows hydraulic oil to circulate through the valve when neither solenoid is energized.

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 proper directional control, smooth hydraulic movement, and unrestricted neutral flow.

What This Part Is Used For

The Stellar 50915 valve directs hydraulic oil to operate a compatible function in two directions. Energizing either side shifts the spool to extend or retract a cylinder or reverse a hydraulic motor. In neutral, its open-center configuration allows hydraulic flow to return through the system at reduced pressure.

Common Reasons For Replacement

Hydraulic function does not move
Function operates in only one direction
Valve spool sticks or shifts slowly
Hydraulic system builds pressure in neutral
Pump or hydraulic oil overheats
Valve produces excessive internal leakage
Hydraulic oil leaks around the cartridge
Manual override or solenoid control fails
