Your cart is empty.This Control Devices ST25-1A225 ASME safety valve has a brass body, a 225 psi relief pressure, a 1/4 inch male NPT threaded inlet connection, and a stainless steel pull ring for manual pressure relief. The valve's brass body, brass valve seat, and the zinc plated steel spring resist corrosion and can be used in operating temperatures up to 250 F. The preset relief pressure is accurate to within +/- 3 percent and a silicon O-ring provides a leak-proof seal to within +/- 10 percent of the relief pressure. This safety valve is American Society of Mechanical Engineers (ASME) safety rated and displays the UV mark for pressure vessel safety valves. It also displays the NB mark for certification in accordance with NB-501, National Board Certification of Pressure Relief Devices. This safety valve has a 199.0098 cubic feet per minute (CFM) flow rate and is suitable for pressure relief applications such as in home construction or industrial air compressors.

The pressure relief valve on my DeWalt compressor was leaking. This was the correct size and dimensions. Easy to install and works fine.

Works good and fit perfect. Doesn’t leak and if you bump it, it doesn’t pop open. Recommend these.

Worked great! Fit like they're supposed to and they don't leak.. 🤷ðŸ¼â€â™‚ï¸ What else can you ask for. I also run them in a really dusty/sandy environment still work fine

Picked this up when my HF compressor (nearly brand new) pressure switch blew out vice cutting out at the 200psi max. Upon inspection, HF had installed a 200 psi switch which triggered before the pressure sensor shut down the motor/pump. This 225pst valve solved my problem in less than a minute.
