First, the electric flange valve Product Overview Sichuan Shanghai company's electric flange valve is a multi-turn actuator and valve flange, which mainly used to connect or disconnect the line of media, not for regulating media flow, Electric flange valve applies pressure, temperature and diameter range is large, especially for the pipe, large diameter. The main advantage of electric flange valve as follows: small (1) fluid resistance, gate valve body within the media channel is straight through, without changing its flow direction when the medium flows through the valve, thus a smaller flow resistance. (2) open and close more effort when opening and closing the gate movement direction perpendicular to the flow direction of the medium, compared with globe valves, gate valves open and close more effort. (3) The general direction of medium flow unrestricted. Medium can flow through the valve in any direction on both sides, can connect or disconnect the purpose of. Ease of installation, the pipeline flow direction is likely to change in the medium. Z941H electric flange valve Second, the electric flange valve Features 1, selected materials, in line with domestic and international standards, high overall quality of the material. 2, in line with the requirements of domestic and foreign advanced standards, reliable sealing, excellent performance and attractive appearance. 3. Sealing pair advanced and reasonable, gate and seat sealing surface with different hardness Stellite (Stellite) cobalt-based alloy cladding made, reliable sealing, high hardness, wear resistance, high temperature, corrosion good anti-abrasion performance, long life. 4, stem quenched and the nitrogen treatment, good corrosion resistance, scratch resistance and abrasion resistance. 5, flexible wedge gate structure, medium and large caliber set thrust bearings, friction force is small, and with a striking manually open and close with ease. 6, can be a variety of standard pipe flanges and flange sealing surface forms to meet various project needs and user requirements.
