Ceramic Full Lined Valve Sunyeh

Sun Yeh Plastic-lined Ceramic Control Ball Valve with F46 and PFA two kinds of materials. It adopts two-piece type floating ball structure with O-port and various degrees of V-port.

PFA, similar to PTFE in thermal properties, can withstand ultra-low temperature and high temperature (maximum continuous working temperature is 260C), and has the characteristics of transparency and processability under high temperature environment. Heating PFA to the same temperature as general thermosetting plastics, besides being applied in extrusion moulding, it also has great working performance.

PFA lined achieves corrosion resistance and penetration resistance; the outer surface can be electropolished to prevent entrainment of pollutants; PFA and metal have good tightness and no gap.

The lining material fully encapsulates the ball and acts as a pressure vessel when fitted with the seat. It ensures that corrosive medium do not touch any external metal components.

Adopting special moulding and injection technology, PFA is lined on the inner wall of valve shell, and spherical surface is combined with precise ceramic seat veneer, which has good sealing performance and realizes zero leakage.

T-groove is embedded in the valve, the lining material is integrated with the shell closely, and there will be no defects such as separation, deformation and ectopic etc; resin is extremely stable; having good chemical resistance and good heat-resistant, does not contain harmful additives and pigments, and the dissolution of organic substance and metal ions situation will not occur; under the condition of high temperature, it also has stretchability, elasticity and good mechanical properties.
