Globe Valve Flanged Wear, High Temperature, Corrosion Resistance
Jun 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 The

Globe Valve Flanged structural features

1, flange valve selection of sophisticated, in line with domestic and foreign standards, reasonable structure, handsome in appearance.

2, Globe Valve Flanged valve, valve seat sealing surface with iron-based alloy surfacing or Stellite (Stellite) cobalt base.

3, hard alloy surfacing, wear, high temperature, corrosion resistance, anti-scratch performance, long service life.

4, flange valve stem quenched and tempered and surface nitriding treatment, a good corrosion resistance and scratch resistance.

5, flange valve can be used with a variety of piping flange and flange sealing surface type to meet the needs of various projects and user requirements.

6, flange cut-off valve body material variety, packing, gasket can be based on actual conditions or user requirements reasonable matching, can be applied to a variety of pressure, temperature and media conditions.

7, flange cut valve sealed with a threaded connection seal or body welded austenitic stainless steel, sealed and reliable, replace the filler can be carried out in the case of non-stop, convenient and quick, does not affect the system operation.

8, easy maintenance, gate valve structure is simple, the seals are generally active, demolition and replacement are more convenient.

9, in full open or fully closed, the ball and the valve seat sealing surface and the media isolation, the media through, will not cause the valve sealing surface erosion.

10, for a wide range of diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.

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.

Applications:

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.
