Hydraulic water level control valve, when the water level in the pool or water tower falls, the float valve is opened to drain, the inlet pipe with pressure water will be the valve piston to hold up, the sealing surface is open, the valve that is open to the water supply, when the water level rises to the control valve, the float valve is closed, the piston moves down to the sealing surface is closed, the valve that is to stop the water supply. Therefore, it is suitable for industrial and mining enterprises, civil buildings in a variety of water tanks (pools), water tower automatic water supply system. Can also be used as atmospheric boiler circulating water supply control valve.

Hydraulic water level control valve is a kind of hydraulic control valve that automatically controls the height of water level in water tank and water tower. When the water level drops over the preset value, the float valve opens, the piston chamber pressure decreases, the piston up and down to form a pressure difference, under the action of this pressure difference, the valve flap opens for water supply operations; when the water level rises to the preset height, the float valve closes, the piston chamber pressure increases continuously, resulting in the valve flap closes to stop the water supply. This is repeated automatically control the liquid level in the set height, to realize the automatic water supply function.

Pressure level control valve features, small float pilot valve operation, hydraulic control of the main valve direct action type, the main valve channel full flow design, head loss is small, the main valve body and the control pilot valve can be combined or installed separately, the control pilot valve is suitable for the main valve body.
