Stellar Industries 50913 Parker 12 GPM Proportional Flow-Control 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 50913 Flow-Control Valve is a Parker three-way, normally closed proportional hydraulic flow regulator identified as model DFA125C31PN. It is configured for a regulated flow of 12 GPM and uses pressure compensation to maintain consistent output as hydraulic load conditions change.

The valve regulates hydraulic flow in proportion to the electrical signal supplied to its solenoid coil. Replacing a faulty valve helps restore smooth speed control, predictable hydraulic movement, and proper distribution of oil between the regulated and bypass circuits.

What This Part Is Used For

The Stellar 50913 valve controls the speed of a compatible hydraulic function by regulating oil flow up to 12 GPM. Excess inlet flow is directed through the bypass circuit while the pressure-compensated design helps maintain stable regulated flow.

Common Reasons For Replacement

Hydraulic function operates too quickly or slowly
Function speed changes unexpectedly under load
Valve does not respond to the control signal
Hydraulic movement becomes jerky or inconsistent
Internal cartridge sticks from contamination
Hydraulic oil leaks around the valve
Solenoid coil or electrical connection is damaged
Regulated or bypass flow is restricted
