Introduction Of Installation Steps Of Stainless Steel Flanged Ball ValveWhen the valve is hoisted, the rope should not be tied to the handwheel or valve stem, so as not to damage these parts.
There are many types of gate valves, and knife gate valve is one of them, also called knife style gate valve. Depending on the type of structure, gate valves can be divided into flat gate valves.
Electric control valve is an important execution unit instrument in industrial automation process control. The structure is composed of an electric actuator and a regulating valve.
The plug valve uses a plug with a through hole as a valve for the opening and closing parts. The cock rotates with the valve stem to realize the opening and closing action.
The opening and closing part of the ball valve is a sphere with a circular channel, which rotates around an axis perpendicular to the channel, and the sphere rotates with the valve stem.
