Features of Butt Welded Slab Gate Valves and Flanged Slab Gate Valves The slab gate valve is a sliding valve whose closing part is a parallel wedge. The closing
The check valve refers to the valve whose valve disc automatically opens and closes depending on the flow of the medium. The check valve belongs to an automatic
In chemical production equipment, some media are highly toxic, flammable, explosive and corrosive, and the working conditions are complex and harsh. When the op
Failures caused by plastic fracture refer to obvious plastic deformation that occurs at the fractured part before the valve parts fracture. Guoyong Liu observed
Failures caused by wear are when the valve part is in contact with the fluid over and over again, and the surface of the part is changed due to wear; the origin
Abstract: Two-way sealed manual and electric butterfly valves with super-large diameters are suitable for water diversion and distribution projects with a water
1. Valve bodies The valve body is of low-alloy structural steel plate Q345C and 25 forged steel welded structure. The fracture surface of the valve body is a do

1. Controlling deformation of super large weldments One of the difficulties in the manufacture of super-large welded butterfly valves is the control of the weld
A stainless steel gate valve is a device used in a fluid system to cut off fluid and has the function of opening and closing. A stainless steel gate valve is co
Actuated valves, though relatively small components they are, have a tremendous market that is expected to reach $125 billion by 2022, according to experts. M
Butterfly valves are mainly used for regulating and switching control of various types of pipelines. In addition, butterfly valves have the advantages of no m
