Level control valves are integral components installed with fluid storage tanks in many applications especially water tanks in a wide range of industries. The function of these valves is not only to maintain sufficient water in the tank but also to prevent the overflow of water when the tank is full.
Modulating Float Valve
Modulating float valves are used in maintaining water at a constant level in water tanks. The float valve opens when the float arm is lowered and closes when the float arm is raised. General float valves have incoming water entering on one side, pushing against a rubber disc while the bouyancy of the float acts against the incoming water pressure to keep the valve closed.
The equilibrium float valve type has a hydraulically pressure balanced design which renders it unaffected by changes in the incoming line pressure.
