                               GV-DS021  DIN  WCB PN25  gate valve                                      

 

Description of PN25 gate valve       :

 

PN25 gate valve   opening and closing of a ram, ram movement direction perpendicular to the direction of flow, gate valve can only be fully open and close, not to adjust and throttling.Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, when the medium temperature is not high for 2 ° 52 '.Wedge gate valve of the damper can be made into a whole body, is called a rigid disc;Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc.
