IID371XCharacteristics of worm gear butterfly valve

1This valve adopts a double eccentric structure, which has a sealing function that becomes tighter as it is closed, and the sealing performance is reliable.

2The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber, which has a long service life.

3The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from.

4The butterfly plate adopts a frame structure, with high strength, large flow area, and low flow resistance.

5The overall baking paint can effectively prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced.

6This valve has a bidirectional sealing function and is not controlled by the flow direction of the medium or the spatial position during installation. It can be installed in any direction.

7The structure of this valve is flexible, labor-saving, and convenient to operate.
