210-09 & 610-09 Combination Altitude and Back Pressure Valve

(210-09 & 610-09)

Cla-Val Pacific Models 210-09 and 610-09 Combination Altitude and Back Pressure Valves control the high water level in reservoirs without the need for floats or other devices.  These valvesmodulate to maintain upstream pressure within close limits to prevent over drawing system supply while filling reservoir.  When the shut-off point of the hydraulic pilot control is reached, the valves close smoothly without surges.  These valves are designed for one-way flow only.  

Typical Applications:
Used on reservoirs where water is withdrawn through a separate line or through a bypass equipped with a check valve.  Valve closes at the desired high water level and reopens for filling when reservoir head lowers below the shut off level.  Valve controls minimum supply pressure to keep from overdrawing supply while filling reservoir.  Water in excess of system pressure flows to reservoir at controlled rate.
