J44N-40 Angle LPG Globe Valve product introduction:

The opening and closing parts of the J44N-40 Angle LPG Globe Valve produced and sold by Baigang Valve Group are plug shaped disc, the sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid.Angle globe valve, also known as Angle valve, stem movement form, there are lifting rod type (stem lifting, hand wheel not lifting), there are also lifting rotary rod type (hand wheel and stem together rotating lifting, nut in the valve body).

Angle globe valve is only suitable for full opening and full closing, not allowed to adjust and throttle.Globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface of the globe valve not to leak.When the medium from the lower part of the disc into the valve, the operation force to overcome the resistance, is the friction force of the stem and packing and the thrust produced by the pressure of the medium, close the "Angle globe valve" force than open the "Angle globe valve" force, so the diameter of the stem to be large, otherwise the stem top bending fault will occur.

J44N-40 Angle LPG Globe Valve Scope of application:
Angle globe valve is a commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, generally not used to adjust the flow.Globe valve products are suitable for a wide range of pressure and temperature, but generally used in medium and small caliber pipelines, suitable for steam, oil, water and other media ≤425℃.
