Series 530C Calibrated Pressure Relief Valves are used in commercial, residential and industrial applications to protect against excessive pressure in systems containing water, oil, or air. It consists of a bronze body construction with NPT threaded male inlet and NPT threaded female (drain) outlet connections, stainless steel spring, brass bonnet, Buna-N disc, and Buna-N O-ring. Series 530C has a calibrated adjustment feature for setting the valve to the required relief pressure, and is ideal for by-pass thermal expansion pressure relief (not ASME approved). Model 530FP is for use in fire protection systems.

Great Product and even better customer service
This is a great product for anyone who needs a small, adjustable relief valve. The pressure may be a little tedious to set at times. This product is great for anyone who is tight on space but also wants a quality relief valve!

Is well made the pressure markings are printed with ink would be nice if the markings were stamped in, otherwise it seems okay.

Relief Valve
I am using this to relieve thermal expansion on a domestic water system. Works great so far (3 weeks).

This was the right item to solve the problem!!!
I'm using this device to help regulate pressure in a fire sprinkler system . Because the system uses a one way check valve, pressure can climb due to city fluctuation. This unit bleeds off excess pressure.

Q: Can this valve be installed horizontally in a radiant system.
Asked by marty 12 years ago
Add your answer
Verified Reply- SupplyHouse StaffIt is recommended that all pressure relief valves be installed in a vertical upright position (spindle vertical) in the case of discharges, and to prevent sediment from fouling the valve.
