Overview
A pressure-reducing valve that uses a diaphragm actuator to regulate downstream pressure.
Consider nominal size, pressure class, fluid, temperature, connection and actuation together. Refer to the technical catalogue for suitable materials and operating limits. Share the fluid, operating pressure and temperature, connection size and standard, and required control function. Include Kv/Kvs for control valves, and condensate load and back pressure for steam traps.
