Electric resilient seated gate valve resilient seated gate valve advantage globe valve, sealing surface can only rely on the closed media pressure to seal, that is, only rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the sealing surface seal, which is self-sealing. Most pneumatic valve is sealed by force, that is when the valve is closed to rely on external pressure to force the gate valve shut-off valve parameters to ensure the tightness of the sealing surface. When you turn electric valve, when the gate valve lift height equal to diameter of 1: 1 times, the fluid channel is completely smooth, but at run time shutoff valve market price, this position can not be monitored. Actual use, is the apex of stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as a fully open valve position. Therefore, the cut-off valve gate fully open position how to sell, according to damper position (ie, travel "to determine the sealing surface wear, affecting life when opening and closing, the friction between the sliding gate and seat sealing surfaces, Under media pressure prone to abrasion and wear, affect the sealing performance and shorten life. Overview of electric power shut-off valve shut-off valve and flange valve belong to the same type of valve, the electric actuator or pneumatic actuator and shut-off valves in two parts composition, the difference in its closure member is a valve, the valve body around the center line rotation to achieve open, and close a valve gate valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow. two-piece ball valve, three-valve, is a new valve has been widely used in recent years. How much is the cut-off valve, Tianchang instrument linked instruments (certification), the cut-off valve provided by the United Instrument Sales Co., Ltd. Tianchang instrument. Tianchang Union City Instrument Instrument Sales Co., Ltd. (www.ylybxs.com) (www.ylybxs.com) is Chuzhou, temperature instrumentation leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs in Tianchang instrument linked instruments leadership with the staff warmly welcome all inquiries negotiations to create Tianchang instrument linked instruments better future.
