Level Control & Pressure Sustaining Valve
With 3-Way Altitude Pilot
753-80-M5-M5M-M5L
700 Large Size Series
Waterworks
Hydraulically operated, level control and pressure sustaining control valve that controls reservoir filling and reservoir level. During filling the valve sustains minimum upstream pressure regardless of fluctuating flow or reservoir level.
The valve shuts off at a pre-set reservoir high level and fully opens in response to an approximately one meter (3 ft) level drop, as sensed by the 3-Way altitude pilot mounted on the main valve.
