Introduction
Angle globe valve is a type of globe valve with an inlet and outlet angle of 90 ° C. In addition to the advantages and usage requirements of general flange globe valves, the biggest feature of this valve is that it is easy to install at the corners of pipeline systems, saving 90 ° C elbows and facilitating opening and closing operations. The flange angle globe valve is widely used in the synthetic ammonia system and refrigeration system of fertilizer plants.
Angle globe valves J44H, J44Y, and J44W are only suitable for fully open and fully closed, and are not allowed to be adjusted or throttled. Globe valves are forced sealed valves, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve below, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than that required to open it, so the diameter of the valve stem should be larger, otherwise the failure of the valve stem bending may occur.
