What kind of valve is this? Internal structure diagram
Thread Content
What kind of valve is this? It is used in pilot hydrogenation units and high-pressure units.
Where is the picture? In this case, well-known imported brands are generally chosen. For regulating valves and angle valves, Fisher, Masoneilan, Summerson, Flowserve, Tooling, etc. are generally available. Optional brands for cut-off gate valves include Hopkinson, Tooling, etc.
Masoneilan 78000 series angle valves are used in the hydrogenation unit. They are candied haws-type valves with a maximum pressure difference of 200 kg. They are mainly used to resist cavitation. Fisher also has this valve, but Fisher can make ordinary valves. For this kind of high pressure difference, Masoneilan is more reliable and has a lot of performance. For working conditions involving hot high-percentage oil, the 77000 series high-temperature-resistant Christmas tree valve may even be used.
A set of Masoneilan valve cores costs tens of thousands, can it be made in China?
For domestically produced hydrogenation unit regulating valves, you can consult Wuxi Yadi. They made the first domestically produced set in 2007, and they should have a lot of performance now.
