Foreged Steel Butt Welding Globe Valve 800lb

The valve body of the forged steel Globe Valve is made of forged steel. It is often used in high temperature and high pressure work scenarios such as power stations. Because the casting material may have blisters and there are safety hazards in the case of high temperature and high pressure, forged steel is used as a suitable material for valve production.

The selection principle is as follows: 1. Globe valve should be selected on the pipeline or device of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high temperature and high pressure pipelines of petrochemical systems. 2. On pipelines where the requirements for convection resistance are not strict. That is, where the pressure loss is not considered. 3. Small valves can choose needle valve, instrument valve, sampling valve, pressure gauge valve, etc. 4. There is flow adjustment or pressure adjustment, but the requirements for adjustment accuracy are not high, and the diameter of the pipeline is relatively small. For example, it should be selected on pipelines with a nominal diameter of ≤50mm. 5. Small fertilizers and large fertilizers in synthetic industrial production should choose high pressure angle globe valve or high pressure angle throttle valve with nominal pressure of PN160 and nominal pressure of 16MPa or PN320 and nominal pressure of 32MPa. 6. In the desiliconization workshop and the pipelines that are prone to coking in the production of alumina Bayer method, it is easy to choose a direct-flow globe valve or a direct-flow throttle valve with a separate valve body, a removable valve seat, and a cemented carbide sealing pair. 7. In the water supply and heating projects in urban construction, the nominal passage is smaller, and the cut-off valve, balance valve or plunger valve can be selected. For example, the nominal passage is less than 150mm.
