wafer metal-seal butterfly valve

PERFORMANCES AND CHARACTERISTICS

1. Compact configuration, small bulk, light, free operation and convenient maintenance.

 2. 3D eccentric seal principle is adopted in desing,so that full seal can be reached and air pressure test leakage is zero.

3. Stainless steel material is used foe seal,and special process treatment is adopted during manufacture.so that it has characteristics of high temperature and corrosion resistant and long service life.

4. it has a large area of flow,with a small flow resistance index and large flow capacity.
