Remote Float Level Control Valve Product Introduction
The diaphragm-type remote float level control valve is a hydraulically operated valve with multiple functions. The remote float level control valve is primarily installed at the water inlet of water tanks or elevated water towers. When the water level reaches the preset height, the main valve is controlled by the float pilot valve to close the water inlet and cease water supply; when the water level decreases, the main valve is controlled by the float pilot valve to open the water inlet and replenish the water tank, achieving automatic water replenishment. The liquid level control is precise and unaffected by water pressure; the remote float level control valve can be installed at any position according to the height of the water tank and the available space. It offers convenient maintenance, adjustment, and inspection, with reliable sealing and a long service life. The diaphragm valve is reliable in performance, high in strength, and flexible in operation. It is suitable for pipes with a diameter of DN450mm or less. For pipes with a diameter of DN500mm or more, it is recommended to use the piston type.
