Stellar Industries 125255 Deltrol Proportional Flow Control Valve – 0–8 GPM

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 125255 Flow Control Valve is a Deltrol proportional hydraulic valve with an adjustable operating range of 0 to 8 GPM. It is designed for compatible Stellar crane hydraulic systems requiring electronically controlled, variable-speed operation.

The valve varies hydraulic flow according to the electrical command from the crane controls. Replacing a faulty proportional valve helps restore smooth acceleration, controlled function speed, and precise load positioning.

What This Part Is Used For

The Stellar 125255 valve regulates the volume of hydraulic oil supplied to compatible crane functions. Its proportional operation allows flow to increase or decrease with the operator’s control input, providing smoother movement than a fixed-flow or on-and-off valve.

Common Reasons For Replacement

Crane functions operate at full speed only
Proportional speed control is unresponsive
Crane movement is slow or inconsistent
Hydraulic flow cannot reach the required rate
Valve sticks or responds with a delay
Internal leakage causes poor performance
Electrical connection or solenoid is damaged
Crane movement surges or becomes difficult to control
