Electric flange straight-through globe valves
Structural features
The main structural characteristics of J941 series electric flange straight-throguh globe valve are: 1, exquisite selection, in line with domestic and foreign standards, with reasonable structure, and beautiful shape. 2, the disc and seat sealing surface adopt iron-based alloy or Stellite cobalt-based hard alloy build up welding, with wear-resistance, high temperature resistance, corrosive resistance, good anti-abrasion performance, long service life. 3, after tempering and surface nitriding treatment, the stem has a good anti-corrosion and scratch resistance. 4, it can adopt a variety of pipe flange standards and flange sealing surface pattern, to meet the various project needs and user requirements. 5, full range of body materials, packing, gasket can be selected and matched reasonably according to the actual working conditions or the users’ requests, and it can be applied to all kinds of pressure, temperature and medium conditions. 6, inverted sealing adopts Screw connection sealing seat or body austenitic stainless steel welding, with reliable sealing, and the replacement of packing can be processed in non-stop, convenient and not affect system operation. 7, matching DZW Multi-return electric devices, with a small shell, light weight, comprehensive functions, and can be used with the remote computer accessory, and also can match the electric device according to customers’ requirements. The valve is applied to the pipes of the petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions that the nominal pressure is PN1.6 ~ 16MPa, and working temperature is -29 ~ 550 °C, works for cutting off or connecting the pipe medium. Driving modes are manual, gear transmission, electric, pneumatic and so on.
