Pressure reducing / pressure regulating valves (PRV) will reduce and maintain a stable outlet / down stream pressure regardless of upstream pressure changes. Each valve can be manually adjusted within the valve pressure adjustment range with the outlet pressure displayed by the pressure gauge.

Pressure sustaining valves (back pressure or pressure maintaining valves). Designed to maintain a set back pressure regardless of downstream pressure or flow demands. Sizes 1/2 to 2" thread or flange DN15 to DN1000.

Pressure Safety valve (PSV) or (PLV) pressure limiting valves are designed to stay closed until the set pressure limit then the relief valve will quickly open releasing excess pressure.

Water hammer arrestors designed to absorb and remove water hammer banging, thumping, clanking and rattling caused by water hammer shock waves.
