American Standard Plug Valve structural features: American Standard Plug Valve for nominal pressure CLASS150-1500LBS, operating temperature -29 ~ 550 ℃ in the petroleum, chemical, pharmaceutical, fertilizer, power industry and other conditions on the pipeline , Cut off or connect the pipeline medium. The main structural features of American Standard Plug Valve: 1, the product structure is reasonable, reliable sealing, excellent performance, handsome in appearance; 2, the valve opening and closing process is in the state of the sealing surface from the state, will not cause the sealing surface Wear and tear 3, two-way flow, installation and use more convenient. 4, parts material and flange size according to the actual conditions or user requirements reasonable matching, to meet the needs of various projects. American Standard Plug Valve works: Opening and closing the valve process: open the valve, you must first rotate the hand wheel, so that the plug rises, the sealing surface detachment, and then turn the handle 90 °, so that the plug passage and the valve body channel Connected to achieve the purpose of opening. The process of closing the valve is to rotate the handle first 90 ° so that the passage of the plug and the passage of the valve body are vertical, and then the hand wheel is rotated to lower the plug to seal.
