Description
A ball valve is a valve whose opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control, among which the hard sealed V-shaped ball valve has a strong shear force between its V-shaped core and the metal valve seat welded with hard alloy, especially suitable for media containing fibers, small solid particles, etc. The multi way ball valve can not only flexibly control the convergence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to their driving methods.

Features
Dayang forged steel gate valve has three types of body cover connection design:
The body cover bolt connection, according to this connection form design of the valve, the valve body and the valve cover with bolt connection, winding gasket seal, the advantage is easy to repair.
The body cover is welded and connected. For valves designed according to this connection form, the valve body and valve seat are fully welded and sealed. The advantage is that there is no external leakage.
Pressure self-tightening valve cover, according to this connection form design of the valve, the valve body and valve cover with threaded connection, internal pressure self-sealing ring seal.
The advantage is that the greater the internal pressure, the better the sealing performance.
You can choose our valves reasonably according to the actual situation.
