J44H/J44Y stainless steel angle globe valve opening and closing parts are plug-shaped valve flap, the sealing surface is flat or conical, the valve flap along the center line of the fluid for linear movement. Angle globe valve, also known as angle valve, the form of movement of the valve stem, there is a lifting stem type (stem lifting, handwheel does not lift), there is also lifting the rotating stem type (handwheel and stem together with rotating and lifting, the nut is located on the valve body). Angle globe valve is only suitable for full open and full closed, not allowed for regulation and throttling. The globe valve belongs to the forced sealing type valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface of the globe valve not to leak. When the medium from below the valve flap into the valve, the operating force to overcome the resistance, is the stem and packing friction and the pressure generated by the medium of the thrust, off the “Angle globe valve” force than open the “Angle globe valve” force, so the diameter of the valve stem to be large, otherwise, the stem will be bent. Otherwise, the valve stem will occur top bend failure.

Scope of application

Angle globe valve is a commonly used disconnecting valve, mainly used to connect or disconnect the medium in the pipeline, generally not used to regulate the flow. The applicable pressure and temperature range of globe valve products is very large, but generally used in medium and small diameter pipeline, suitable for ≤ 425 ℃ steam, oil, water and other media.
