J41H forged steel flange globe valve refers to a valve where the closing part (disc) moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the valve disc stroke. Due to the relatively short opening or closing stroke of the valve stem and the highly reliable cut-off function, as well as the proportional relationship between the change of the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow. Therefore, this type of valve is very suitable for use as a cut-off or regulating and throttling device.

Practical Selection
1. Globe valves should be selected on pipelines or devices with high temperature and high pressure media. Such as thermal power plants, nuclear power plants, and high-temperature and high-pressure pipelines in petrochemical systems.
2. On pipelines with less strict requirements for flow resistance. That is, places where pressure loss is not considered much.
3. Small valves can choose needle valves, instrument valves, sampling valves, pressure gauge valves, etc.
4. There is flow regulation or pressure regulation, but there is not a high requirement for regulation accuracy, and the pipeline diameter is relatively small. For example, on pipelines with a nominal diameter of ≤ 50mm, it is recommended to choose.
5. Small and large fertilizers in synthetic industrial production should use high-pressure angle globe valves or high-pressure angle throttle valves with a nominal pressure of PN160 and a nominal pressure of 16MPa or PN320 and a nominal pressure of 32MPa.
6. In the production of alumina by Bayer process, in the desilication workshop and on pipelines prone to coking, it is easy to choose DC globe valves or DC throttle valves with separate valve bodies, removable valve seats, and hard alloy sealing pairs.
7. In the water supply and heating engineering of urban construction, for pipelines with smaller nominal diameter, cut-off, balance valves or plunger valves can be selected, such as on pipelines with a nominal diameter less than 150mm.
