73000 Series Sweep Angle Valve

Erosive Service Solutions for Gasification Processes

The 73000 Series is designed for erosive applications commonly found in gasification processes. Basic construction includes a contoured body and specialty trim materials, making it ideal 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 provides the highest level of resistance to potentially damaging erosion effects in these types of severe applications.

Key Features

The 73000 Series is designed for severely erosive applications using a sweep angle body design along with specialty materials to provide high hardness for improved resistance on critical valve surfaces. Trim components are available in a wide variety of special materials including stellite, tungsten carbide and ceramics. The 73000 Series design also includes an integrated body and bonnet design and heavy stem guiding.

Benefits

The 73000 Series provides an extremely high level of resistance in erosive-type applications thus providing a highly reliable solution for maintaining process uptime under these severe conditions. It is an excellent solution for slurry services and two-phase flow applications, providing accurate and efficient process control using the heavy guiding and contoured plug design. Special seat designs provide flexibility for direct mounting to different vessel configurations.

Selection Criteria

Control valve applications with high levels of flashing are often installed directly mounted to a large volume flash tank. The 73000 Series control valve is specifically designed for such applications with a body and trim designed to be directly flanged to a flash tank. The 73000 Series can also feature an extended seat venturi to provide a safer way to direct the high velocity flashing fluid into the tank and minimize direct impingement on the tank walls.
