The American standard lifting hard sealing plug valve is suitable for oil, chemical, pharmaceutical, chemical fertilizer, power industry and other working conditions of the pipeline, cutting or connecting the pipeline media.The valve body and sealing surface of the plug valve are provided with oil groove, which can be used to inject sealing grease into the valve seat at any time to increase the sealing performance.The material and flange dimensions of the parts can be selected according to the actual working conditions or users' requirements, and meet all kinds of engineering needs.
Product structure features:
American standard lift hard seal cock valve used in nominal pressure CLASS 150-600 LB, working temperature -29 - 550℃ in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as the pipeline under various working conditions, cut off or connect pipe medium.
Its main features:
1. Reasonable product structure, reliable sealing, excellent performance and beautiful appearance.
2. The opening and closing process of the valve is carried out in the state of the sealing surface, which will not cause the wear of the sealing surface.
3. Two-way flow, easier to install and use.
4. The material and flange dimensions of the parts can be selected according to the actual working conditions and users' requirements, so as to meet various engineering needs.
Principle of valve opening and closing:
The valve opening and closing process: open valve, rotating the handwheel, make plug up, away from the sealing surface and in the 90°rotating the handle, the plug of the channel and the body is linked together, thus attaining the goal of open.And the process of opening and closing is 90°rotating the handle first, make the plug of the channel and the body vertical, then rotate the hand wheel, make plug drops, a seal.
