It consists of a bronze body construction with NPT threaded male inlet and NPT threaded female outlet, sensitive rubber diaphragm, Buna-N disc, spring and adjustment handle, and a tee handle.

Common Questions
- What pressure does this relieve at?
- This is a calibrated valve — you set it. It adjusts over 75-175 psi, so it has no factory set point. Set it below the working pressure rating of the equipment you are protecting, and re-check the setting after installation.
- Can I use this on potable water?
- No. This model is not certified lead-free, so it cannot be installed in a potable (drinking) water line under the NSF/ANSI 372 weighted-average lead rule. Use it on non-potable service, or order the "LF" version of this model for potable water.
