Globe Valve Precision Casting Properties

Globe valve precision casting is one of our main precision casting products. The opening and closing member of globe valve is a plug-shaped flap closing member, the sealing surface is flat or tapered, and the valve flap moves linearly along the center line of the fluid. According to this form of movement of the valve flap of the stop valve casting, the change in the valve seat opening is proportional to the valve stroke. Due to the relatively short opening or closing stroke of the valve stem of this type of valve, and the very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve flap, it is very suitable for the adjustment of the flow rate. Therefore, this type of cut-off valve is well suited for shut-off or adjustment and throttling.
The globe valve is the most widely used type of valve. It is popular because of the small friction between the sealing surfaces during the opening and closing process. It is relatively durable and has a low opening height. The cast steel globe valve castings are easy to manufacture and easy to maintain. Not only for medium and low pressure, but also for high pressure.
Globe Valve Precision Casting Properties
The riser of globe valve precision casting is arranged reasonably, and all the isolated hot sections can be supplemented. The disadvantage is that the riser is not easy to cut. The surface shape of the globe valve casting is ensured by a large amount of gouging and grinding, and cracks are easily generated. Excessive riser, resulting in uneven thickness of the casting structure, large shrinkage stress, and easy to produce crack defects.
