Pressure reducing Valves (PRV) reduce and maintain a stable outlet downstream pressure regardless of inlet pressure changes. The outlet pressure is displayed by the pressure gauge and the pressure can be manually adjusted and set.

Pressure sustaining Valves (BPV) back pressure valves maintain a minimum inlet or back pressure regardless of downstream outlet demands. The inlet pressure is displayed by the pressure gauge and the pressure can be manually adjusted and set.

Safety Pressure relief Valves (PLV) pressure limiting valve are designed to stay closed and will quickly open if system pressure reaches the preset maximum. These safety valves will control or limit the pressure that might otherwise build up and damage process systems, instruments and equipment. The inlet or system pressure is displayed by the pressure gauge, and pressure limit can be manually adjusted and set.
