Structural characteristics of imported hard sealing plug valve
Flange connection American standard enhanced sealing plug valve for nominal pressure CLASS150-1500LBS, operating temperature -29 ~ 550 ℃ in petroleum, chemical, pharmaceutical, fertilizer, power industry and other conditions of the pipeline, cut off or connected Pipeline media. ◆ imported hard sealing plug valve its main structural features 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 sealing surface detachment, will not cause the sealing surface of the 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. ◆ Opening and closing the valve working principle Opening and closing the valve process: open the valve, the first hand wheel rotation, so that the plug rises, the sealing surface detachment, and then rotate the handle 90 °, so that the plug passage and the body of the channel connected to reach Open the purpose. 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.
