Triple Eccentric hard sealing butterfly valve


Tri-eccentric hard sealing butterfly valve is new product, which product by this company with log service life and energy saving. The product measures up national standard of JB/T8527-1997(metallic sealed butterfly valve) or API609-2004 Butterfly valves, double flange, lug-and water-type, GB/T 13927-1992(general valve pressure test) and regulations about other relative standard of valve.

This product is composed of body, disc, gasket, operating device etc. The structure design according to principle of three dimensional eccentricity, new processing technology of flexible seal and hard & soft multiple layers seal, when the butterfly valve operation, it can reduce the twisting force, reach to the function of saving labor and energy. Thereby ensure holistically antisepsis, high temperature-resistant, wearable reliability of valve. The main characteristic such as:

1Particular structure, small bulk, operation skillfully, laborsaving, conveniently ;
2Seal reliably, it can reach to gas seal with no leakage;
3Flux capability to direct line and best adjusting capability;
4It adopts the principle of three-dimensional eccentricity, and facing near zero wearing, prolong service life of valve;
5Appropriate differ temperature and thereinafter of
6.4Mpa pressure class, resistant wearable medium tube and so on;
6Wide applied range, it can use medium such as: water steam oil air gas etc.
