Three eccentric hard-seal butterfly valve

1. This butterfly compact structure, small size, light weight, flexible operation, easy maintenance.
2. Designed with three principles of eccentric seal, sealing and reliable performance.
3. Sealing selection of stainless steel material, and in the manufacturing process for a special craft processing, high temperature, corrosion resistance, long service life characteristics.
4. Over-current area, flow resistance coefficient is small, large flow capacity.
5. Anti-aging, engaged in radiation, durable.
