40-25 & 640-25 Combination Rate of Flow and Pressure Sustaining Valve

(40-25 & 640-25)

Cla-Val Pacific 40-25 and 640-25 Rate of Flow and Pressure Sustaining Valves automatically limit the maximum flow rate, regardless of changing line pressure or demand. It also sustains the upstream pressure to a pre-determined minimum.

Install the 40-25 or 640-25 Rate of Flow and Pressure Sustaining Valves where the water supply to a system must be limited to a preset flow to prevent lowering the supply pressure.
