Principle function of D371X worm wheel wafer butterfly valve:

 The butterfly valve opening and closing part of Shanghai Wafer Butterfly Valve Company is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The advantages of butterfly valves are simple structure, small size, light weight, small installation size, and rapid switching.

D371X Worm Gear Wafer Butterfly Valve Performance Features:

    ①This valve has unique structure, flexible operation, labor saving and convenient;

    ②The butterfly plate adopts a frame structure, with high strength, large flow area and small flow resistance;

    ③Stainless steel and nitrile oil-resistant rubber are selected for the sealing pair, which has a long service life;

    ④This valve adopts a double eccentric structure, which has a tighter and tighter sealing function and reliable sealing performance;

    ⑤The overall baking varnish can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is replaced;

    ⑥The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to media with different characteristics for users to choose;

    ⑦The valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation, and is not affected by the spatial position. It can be installed in any direction.
