Metall zu Metall Dichtungsschmetterlingsventil

GYPYD363H hard impact hard welding butterfly valve isoptimized by our technical personnel after absorbing thestructure and characteristics of foreign similar products andovercoming the defects existing in the use of the originaproducts, making its service life more durable and sealing morereliable. The butterfly valve adopts the three-dimensionaeccentric design principle, and the sealing pair is composed ottwo overlapping cone inclined sections. After the eccentric valueof the valve body and valve seat, the buterly plate rotation center can reaize the instantaneous contact and separation of opening and closing. Thelabyrinth seal is reaized by the aminated structure of buterly plate seaing ring metal and graphite, which can not only reduce the switching torgue oithe valve, but also ensure the sealing performance of the buterly valve Pressure buterly valve adopts reducing eccentricity value and enhancingstrength of butterfly plate, valve shaft and actuator to realize zero leakage of inlet and outlet bidirectional seal of butterfly valve.

Structural characteristics

1. Compact structure, small size, light weight, flexible operation, easy to use;

2. The three-dimensional eccentric multi-layer hard sealing structure is adopted, and its sealing performance is reliable and reaches zero leakage；

3. The valve has no flange, which brings great convenience and beauty to the insulation and wrapping of pipeline; 4. lt has the characteristics of hiah temperature, hiah pressure, corrosion resistance and wear resistance.
