Metall Sitz Schmetterlingsventil

GYPYD363H hard impact hard welding butterfly valve is optimized by ourtechnical personnel after absorbing the structure and characteristics offoreian similar products and overcoming the defects existinag in the use of theoriginal products, making its service life more durable and sealing morereliable. The butterfly valve adopts the three-dimensional eccentric designprinciple, and the sealing pair is composed of two overlapping cone inclinecsections, After the eccentric value of the valve body and valve seat, thebutterfly plate rotation center can realize the instantaneous contact andseparation of opening and closing. The labyrinth seal is reaized by the laminated structure of butterly plate sealing ring metal and graphite, which can not onyreduce the switching torque of the valve, but also ensure the seaing performance of the buterly valve Presure butterly valwe adopts reducing ecentricity valueand enhancing strength of butterfily plate, valve shaft and actuator to reaize 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 seaing structure is adopted, and its seaing 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 high temperature, high pressure, corrosion resistance and wear resistance
