The centric butterfly can be made of cast steel, stainless steel or alloy steel. It is widely used in pharmaceutical, chemical, petroleum, textile, papermaking and other industries, the working environment is generally between 80 to 120 degrees, following a brief introduction to the midline of the folder type butterfly valve features:
(1) the seat can be replaced, reliable sealing performance to achieve two-way seal zero leakage; (2) special seal structure under high temperature and cold working conditions, sealing without stress and deformation, can achieve zero leakage;
(3) adopt axial positioning device, solve the difficult problem of leakage at the axial seal and the sealing surface easy wearing, drive actuator can be install at any direction.
