Flanged hard seal butterfly valve has the following characteristics:

1. Butterfly plate sealing ring is a laminated metal sheet with soft and hard layers. It has the dual advantages of metal hard sealing and elastic sealing, and has excellent sealing performance regardless of low temperature and high temperature.

2. the use of three-dimensional eccentric structure, seat and butterfly plate almost no friction, with more close more tight sealing function.

3.valve body sealing surface, using surfacing stainless steel, cobalt-based hard alloy, sealing surface wear resistance, long service life.

4.unique structure, flexible operation, labor-saving, convenient, not affected by high and low medium pressure, reliable sealing performance.

Structure features of wafer butterfly valve

1. The unique design of three-way eccentric drives the sealing face without friction and prolongs the service life of the valve.

2. Elastic seal produced by torque.

3. the ingenious wedge design makes the valve more and more tightly closed automatic sealing function, with compensatory, zero leakage between sealing surfaces.

4.small size, light weight, light operation, easy to install.

5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

6. replacement parts material can be suitable for all kinds of media, and can be lined with anti-corrosion (lining F46, GXPP, PO, etc.).

7. continuous structure diversification: clamp, flange, butt welding.
