Cla-Val Pacfic's Models 92-01 and 692-01 Combination Pressure Reducing and Pressure Sustaining Valves automatically perform two independent functions. They maintain a constant downstream pressure, regardless of fluctuating demand and sustains the upstream pressure to a pre-determined minimum.
A Combination Pressure Reducing and Pressure Sustaining Valve is typical used to automatically reduce pressure for the downstream distribution network and sustain a minimum pressure in the high pressure main regardless of distribution demand.
