Power station valve product introduction:
Power station valve also known as special cut-off valve, power station valve compared with other valve products is characterized by high temperature and high pressure, special since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products. Manufacturing acceptance conditions according to the provisions of the Japanese power valve standard E101. Class structure of the power station valve length according to E101 rules. The valve body welding groove according to the provisions of the ANSI B16.25 or according to the size of provided by the user. Try reasonable cover packing box, packing and corrosion inhibitor, reliable sealing, smooth switch. Valve on the sealing structure, which can guarantee the open run-time stem not valve leakage.
Power station valve application:
Power station valve suitable for Class1500-29 ~ ~ 3500 lb, working temperature 570 centigrade degree under various working conditions such as petroleum, chemical industry, power plant piping cut off or connect medium. Applicable medium: water, oil, steam and other corrosive medium.
Power station valve structure features:
- The product design and manufacture according to ASME B16.34, standard E101, can be used with imported equipment equipped with.
- The valve lumen self-tightening seal structure is adopted, and the inner cavity pressure, the higher the sealing performance, the better.
(3) for butt welding on both ends of the branch pipe, different to meet the demand of the takeover. - The disc and seat sealing surface using stellite department too vertical cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good abrasion resistance, long service life.
- Try reasonable cover packing box, packing and corrosion inhibitor, reliable sealing, smooth switch.
- The valve on the sealing structure, which can guarantee the open run-time stem not valve leakage.
- Electric cut-off valve opening and closing control by electric actuator, electric actuator, respectively, with special motor, reducer, torque control, site operation, manual, electric switching mechanism. In addition to on-site operation, remote operation can be performed.
