Possible issues during the use of clamp type fluorine lined butterfly valves

clamp-on Fluorine-lined Butterfly Valve What problems may exist during use?
1 Clamp type fluorine lined butterfly valve The sealing ring is fixed on the valve body in a multi-layer soft hard stacking form, so when the valve body is in a normally open state, the medium flows in and flushes the sealing surface on the front side. If used for a long time, the sealing performance will be more or less affected;
2、 Due to the structural limitations of the clamp type fluorine lined butterfly valve itself, it is not possible to manufacture valves smaller than eight inches. The main reason is that the valve plate of the clamp type fluorine lined butterfly valve requires a large thickness and high fluid resistance.
3、 Due to the principle of the clamp type fluorine lined butterfly valve, the valve plate is pressed against the valve seat by the torque transmitted by the transmission rotor to achieve sealing. In the positive flow state, the higher the medium pressure, the tighter the seal. However, if the medium pressure is greater than the pressure between the valve body and the valve seat in the reverse flow state, the sealing performance begins to deteriorate.
