Flanged steel gate valve high pressure large domestic and international standards in line with the requirements of advanced, reliable sealing, excellent performance, attractive appearance. Gate and seat sealing surface with iron based alloy or Stellite (stellite) cobalt-based alloy, wear resistance, high temperature valves numbers Foshan, corrosion resistance, good anti-abrasion performance, service life long. Large high pressure flange valve stem quenched and the nitrogen treatment, with good corrosion resistance and scratch resistance out. M cover flexible wedge gate valve structure, medium and large caliber set rolling friction is small, open and close easily. Can be a variety of standard pipe flanges and flange sealing surface types to meet various project needs and user requirements. High-voltage large flange steel gate for nominal pressure PN10.0 ~ 25.0Mpa, petroleum pipeline, chemical, fire station and other conditions of the working temperature of -29 ℃ ~ 600 ℃, or turn off the media. Large Flanged steel high pressure valve Suitable medium: water, oil, steam and so on. Operating modes: manual, gear transmission, electric and so on. 1. small fluid resistance, the resistance coefficient equal to the same length of pipe. 2. Simple structure, small size, light weight. 3. Close and reliable valve sealing surface material widely used plastic, sealing, and has also been widely used in the vacuum system. 4. Easy to operate, the valve opening and closing rapidly, from fully open to fully closed as long as the rotation 90 °, to facilitate remote control. 5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient. 6. In the fully open or fully closed, sealing surface and the dielectric isolation ball and seat valve supply Foshan, Foshan valve manufacturer, does not cause erosion of the valve sealing surface through the media. 7. wide scope of application, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, in the import and export of office should be fully rendered sphere, thus cutting off the flow. Foshan professional sales valves, electromechanical England (certified), the valve is provided by City Electrical Equipment Co., Ltd. of England. England City Electrical Equipment Co., Ltd. (www.gdyinglun.com) is a leader in Dongguan, Guangdong, hydraulic machinery and parts, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
