Product Structure

This company has produced new product of multiple layers hard sealing butterfly valve with long service life,energy saving.The configuration adopt threedimensional eccentric principle to be designed,seat use hard&soft hermetical multiple configuration,exquisite process,advanced technology.and this product is complsed of body.discseat with multple layerstem.operative mechanical etc.

Characteristic

Because this butterfy valve adopt three-dimensional eccentric principle to design,makes the movement track on facing space reach to idealization, and there are no attrition and no intrtvene between hermerical components,furthermore,the hermetical material has bern selected reasomably,thereny it ensure hermetic,10.antisepsis,wearable capability of valve.The main characterstic as below.

1.Tiny moment for starting,flexible and convenient,save labor and energy.

2.Three-dimensional essentric configuration forces disc close tighter and tighter.and reach to reliable hermetic capability and with no leakage.

3.It has charactenistic of high temperature resistanthigh presure resistantmantisepsis,wearable,long service life etc.
