On-Off Float Control Valve with Pressure Sustaining Feature
Series LFF110-18, LFF1110-18 On-Off Float Control Valve with Pressure Sustaining Feature is designed to open fully or close drip-tight as commanded by the Float Control Pilot, and throttles to sustain a minimum upstream pressure during tank filling operations. The Float Pilot may be either valve or remote mounted. The valve closes drip tight when water level reaches the adjustable high-level setpoint, and opens when water level is below the adjustable low-level setpoint, allowing a calculated draw-down of water level to increase tank circulation. High and low levels are separately adjustable by positioning stop collars on the float rod(s) at desired opening and closing setpoints. If desired, the on-off action of the valve can be reversed by modifying the hydraulic connections of the On-Off Float Pilot.
