Under the action of the fluid pressure flowing in one direction, the valve disc opens, when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve disc act on the valve seat, thereby cutting off the flow.Among them, the swing check valve belongs to

The difference between rising stem gate valve and non-rising stem gate valve:1. The rising stem gate valve can see the screw rod, but the non-rising stem gate valve cannot see the screw rod.2. The rising stem gate valve raises or lowers the valve clack through the threaded transmission of the valve

Features of Electric Flange Gate Valve:1.The valve adopts pressure self-tightening seal or valve body and bonnet gasket seal structure, which is safe and reliable to use.2. The valve disc adopts the structure of double rams with universal top in the middle, which can automatically adjust the c

Features of Chain Drive:1.Chain transmission is a widely used mechanical transmission, which relies on the meshing of sprocket teeth and chain links to transmit movement and power.2.Compared with belt transmission, chain transmission can maintain an accurate average transmission ratio, high transmis

The characteristics of the resilient seated gate valve non-rising stem:1. The gate adopts a whole encapsulation, and its good covering performance and precise geometric dimensions ensure reliable sealing and longevity.2. Light weight: the valve body is made of ductile iron, which is light in weight
