Globe Valve Flanged Wear, High Temperature, Corrosion Resistance
Oct 22, 2017
Globe Valve Flanged structure is reasonable, excellent performance, handsome in appearance, the application of a wide range of pressure, mainly used to connect or cut off the pipeline in the medium, with wear resistance, high temperature, anti-scratch performance, long life and other advantages.
Flange shut-off valve opening and closing parts are plug-shaped discs, sealing surface was flat or conical surface, the valve flap along the center line of the fluid for linear motion, flange valve body structure in the form of straight-through, Right angle.
Globe Valve Flanged works:
Globe Valve Flanged is forced to seal the valve, so the valve is closed, the pressure must be applied to the valve to force the sealing surface does not leak. When the medium from the bottom of the valve into the valve six, the operating force to overcome the resistance is the stem and packing friction and pressure generated by the medium thrust, off the valve force than the valve, so the valve Rod diameter to be large, otherwise there will be stem stem bending failure.
Globe Valve Flanged structural features:
1, Globe Valve Flanged compact structure, handsome in appearance, excellent performance. Valve and stem with active connection structure, open and close flexible, stem design of the inverted seal to improve the valve life and sealing performance.
2, flange sealing valve sealing material matching reasonable, the valve flap in the operation and the seat of the friction is very small, long service life.
3, Globe Valve Flanged stem surface by nitriding treatment, has good corrosion resistance, anti-friction. Filler with PTFE material, sealed and reliable, flexible operation, opening and closing torque is small.
4, flange valve can choose a variety of piping flange and flange sealing surface type, but also optional manual, worm gear, electric, pneumatic, hydraulic and other drive to meet the different needs of users.
Globe Valve Flanged use:
Globe Valve Flanged for the nominal pressure PN1.6 ~ 16.0Mpa, the working temperature -29 ~ 550 ℃ of oil, chemical, pharmaceutical, fertilizer, power industry and other conditions on the pipeline, cut off or connected to the media. Applicable medium: water, oil, steam, acidic media. Operation methods are: manual, gear drive, electric, pneumatic.
High-pressure GB cast steel gate valve for nominal pressure 4.0 MPa ~ 10.0 MPa slope conversion (1 MPa = 10 kg), the working temperature of twenty to nine to six hundred degrees Celsius oil, chemical, pharmaceutical, fertilizer, electricity Industry and other conditions of the pipeline, cut off or connected to the pipeline medium, can not be adjusted and throttling. Applicable medium: water, oil, steam, acid media and so on.
