Product introduction:

Globe valve is closed. (disc) along the valve seat centerline mobile.According to this mobile form of disc, seat and disc change in his itinerary directly proportional relationship.

Due to open or close the valve stem travel relatively short, and very reliable cutting function, and due to the change of his seat and disc stroke proportional relationship, is very suitable for the traffic regulation.Therefore, this type of valve is well suited for use as cut off or adjust and throttling.

Selection principle:

1, high temperature and high pressure medium or device appropriate chooses cut-off valve.Such as power plants, nuclear power stations, petrochemical system of high temperature and high pressure piping.

2, convection resistance is relaxed on the pipeline on the pipeline.Thinking about small place of pressure loss. 

3, small valve can choose needle valve, instrument valve, the sampling valve, pressure gauge valve, etc.

4, there is flow control or pressure adjustment, but the adjustment accuracy is not high, and pipe diameter and the relatively small, such as nominal drift diameter of 50 mm or less piping, appropriate chooses.
