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!

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.

It 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.
