Worm Wafer Type Butterfly Valve
Introduction:
The worm wafer type butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. And it only needs to rotate 90° to open and close quickly, the operation is simple, and the valve has good fluid control characteristics.
Features:
1. The valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation, nor is it affected by the spatial position. It can be installed in any direction.
2. The butterfly plate adopts frame structure, which has high strength, large flow area and small flow resistance.
3. The valve adopts double eccentric structure, which has the sealing function of tighter and tighter, and the sealing performance is reliable. 4. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be applied to media with different characteristics for users to choose.
5. The sealing material is made of stainless steel and nitrile oil-resistant rubber, which has a long service life.
6. The overall paint can effectively prevent corrosion and can be used for different media as long as the sealing material of the sealing valve seat is replaced.
