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.
Pilot Operated Float Valve
Pilot operated float valves maintain water either at a constant level (modulating pilot) or at a set high and low level (high-low pilot) in a water tank. The high-low pilot opens the main valve when water level in the tank is low and closes it when water level is high. It has the flexibility of resetting the high-low level of the water tank by adjusting the two stoppers along the float rod. The pilot float can be installed either on or away from the main valve.
