Pressure Relief Valve 175 psi ASME
The PowerMate 136-0077RP is a pressure relief valve rated at 175 psi and built to ASME standards. It protects air compressors by venting excess pressure when the system limit is reached. The valve fits a range of compatible models from brands such as Dewalt, Industrial Air Contractor and Powermate. Installers can cross-reference Grainger part numbers 41RC93, 41RC94, 41RC96, 41RC97, 41RC98 and 43AG29 for fitment confirmation.
Sustained pressure protection
Under continuous compressor operation the valve opens at the factory-set 175 psi threshold and reseats once pressure drops below that level. ASME certification confirms the valve meets code requirements for repeated cycling without degradation of the spring or seat. The design prevents pressure creep during long duty cycles, keeping the tank and downstream components within safe limits. No adjustment or field calibration is required after installation.
Critical specification 175 psi set pressure
The single figure that decides suitability is the 175 psi relief setting; the compressor’s maximum working pressure must match this value exactly. A lower or higher set pressure will either open prematurely or fail to protect the vessel. Verify the stamp on the existing valve or the compressor nameplate before ordering. California Proposition 65 warnings apply to this product.

Questions about this item
How much heat or noise does the 136-0077RP relief valve produce when the compressor runs continuously?
The valve is a passive safety device with no moving parts that generate heat or sound; it simply vents excess pressure at 175 psi and remains silent during normal operation.
Which compressor thread size must I already have for the 136-0077RP to install correctly?
The valve fits standard NPT threads used on Dewalt, Industrial Air Contractor and Powermate tanks; confirm your tank’s port size matches before ordering.
Will the 136-0077RP work on an older Dewalt or Industrial Air compressor I already own?
Yes — the valve cross-references Grainger parts 41RC93, 41RC94, 41RC96, 41RC97, 41RC98 and 43AG29, covering many legacy Dewalt and Industrial Air models.
