Modulating Float Control Valve W/ Solenoid(ON-OFF) Feature

Envotec Model E5100-14 Pilot Operated Modulating Float Control Valve with Solenoid ON/OFF Feature designed to maintain water level with modulating float pilot assembly in a reservoir or tank as a primary function and electric solenoid pilot as secondary safety function. Buoyancy of float pilot assembly throttles main valve to open on a lowering water level and throttles to close upon a rising water level. The valve proportionately begins to close upon a rising water level and drip-tight at the maximum level reached. The float pilot assembly is remotely (inside water tank) installed where the main valve installed externally is inter-connected with a sensing tube(field installed) to operate main valve. The additional normally open secondary safety electric solenoid pilot in series with modulating float control pilot will only operate (by signal from electronic level sensing module connected with water level electrodes) in the event of primary modulating float pilot malfunctions or fails and close the main valve by protection of overflow.
