Easy maintenance | Globe valve | Reliable performance

This type of shut-off valve is a modification of the conventional shut-off valve. In this valve, the disc and valve seat are usually designed based on the plunger principle. The valve clack is polished so that the plunger is connected to the valve stem, and the sealing is achieved by two elastic sealing rings sleeved on the plunger. The two elastic sealing rings are separated by a collar, and the sealing ring around the plunger is pressed firmly by the load exerted on the bonnet by the bonnet nut. The elastic sealing ring can be replaced and can be made of various materials. The valve is mainly used for "open" or "close", but it is equipped with a special form of plunger or a special collar, which can also be used to adjust the flow rate .

In terms of service life, the sealing surface of the globe valve is not easy to wear and scratch. During the opening and closing process of the valve, there is no relative sliding between the valve disc and the sealing surface of the valve seat, so the wear and abrasion of the sealing surface are small, so the sealing is improved. During the full closing process of the auxiliary service life cut-off valve, the disc stroke is small, and its height is smaller than that of the alarm valve.

The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located. The valve clack exerts pressure to make the sealing surface of the valve clack closely fit the sealing surface of the valve seat, and prevent the medium from leaking along the gap between the sealing surfaces.
