Remote control float valve
Product model:W811/W831
        Juhan Valve's W811 / W831 remote control float valve is hydraulically driven to maintain the water level in the storage tank. At a relatively stable level, the float control switch is installed at the high level of the storage tank and is connected to the main valve through a pipeline. When rising and exceeding the maximum water level, the float switch is completely closed and the valve is automatically closed.
         When the water level drops to the lowest limit, the float switch is fully opened, and the valve is automatically opened for water replenishment, until the water level in the water tank is controlled within the stable ideal range.
         If the optional non-return feature is added, when the reverse pressure is generated, the returned liquid enters the air chamber to close the valve, preventing the liquid from returning.
 
Product Highlights
         Precise and repeatable water level control, ideal slow opening and slow closing functions, reliable full hydraulic control, reliable airtightness, large flow rate, built-in filter device to prevent piping system from being blocked.
