Stellar Industries C4914 HydraForce Hydraulic Relief Valve – 3,000 PSI

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 C4914 Relief Valve is a HydraForce direct-acting hydraulic cartridge designed for compatible Stellar compressor systems. Model RV10-22A-0-N-35/30 is factory set to relieve at approximately 3,000 PSI and has a maximum flow rating of 30 GPM.

This poppet-style valve protects the hydraulic circuit from excessive pressure by opening when pressure reaches its calibrated setting. Its low-leakage design, rapid response, and adjustable Allen-head configuration support dependable pressure control in demanding mobile applications.

What This Part Is Used For

The Stellar C4914 valve limits maximum hydraulic-system pressure. It normally blocks flow until inlet pressure reaches the relief setting, then opens to divert excess oil and protect pumps, motors, hoses, seals, and other hydraulic components from overload damage.

Common Reasons For Replacement

Hydraulic pressure exceeds the specified limit
Valve opens below the correct pressure
Compressor cannot maintain operating pressure
Relief valve leaks internally
Hydraulic oil leaks around the cartridge
Valve remains stuck open or closed
Pressure fluctuates during operation
Poppet or valve seat is worn or contaminated
Adjustment mechanism is damaged
