American Standard Welding Plug Valve Brief Description:
The plug valve has a simple structure, a quick switch, a small fluid resistance, and a fast angular stroke operation. In an emergency such as an accident, the pipeline can be quickly connected or disconnected. Compared with gate valves and globe valves, the operation is more flexible and the switch is faster. The plug valve uses a plug body with a through hole as the opening and closing member, and the plug body rotates with the valve stem to realize the opening and closing action.
American standard welded plug valve application range:
American standard socket welding ferrule valve is suitable for pipelines of nominal pressure CLASS150～CLASS600LB, working temperature of -29°C～180°C for petroleum, chemical, pharmaceutical, fertilizer, electric power industry, etc. Pipeline media.
American standard welded plug valve structure features:
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2, the sealing of the socket welding plug valve is achieved by the sealing surface around the ferrule. Unique 360° metal lip protection ferrule.
3. The valve has no cavity to accumulate the medium.
4, the metal lip provides self-cleaning effect when the cock is turned, suitable for viscous and easy scaling.
5, two-way flow, easy to use and install.
6. The material and flange size of the parts can be reasonably matched according to the actual working conditions or user requirements to meet various engineering needs.
