Masoneilan* 73000 Series Sweep Angle Valve


The Masoneilan 73000 Series features a sweep angle configuration for throttling in the erosive applications commonly found in gasification processes. Basic construction includes a contoured body and specialty trim materials, making it well-suited for black water handling systems used in the gasification of coal, petroleum coke, oil or other feed-stocks. The sweep angle body of the 73000 Series offers a high level of resistance to potentially damaging erosion effects in these types of severe applications.  




Features & Benefits

• Extremely high level of resistance in erosive-type applications for maintaining process uptime under these severe conditions
•Heavy guiding and contoured plug design offer accurate and efficient process control for slurry services and two-phase flow applications
• Special seat designs support direct mounting to different vessel configurations
Application :

The Masoneilan 73000 Series valve offers erosion resistance for black water handling systems and applications such as:



•Coal slurry

•Ash handling

•Hydrocarbon bottoms

•Petroleum coke

• Oil

• Other feed stock

Control valve applications with high levels of flashing are often directly mounted to a large volume flash tank. The 73000 Series control valve features a body and trim design that can be directly flanged to a flash tank. The sweep angle body and specialty materials resist erosion on critical valve services. The 73000 Series design also includes an integrated body and bonnet design and heavy stem guiding.
