74000 Series Heavy Oil Process Valve

Heavy Oil Process Solutions

The Dresser Masoneilan 74000 Series control valve is designed to effectively handle the difficult services associated with heavy oil applications. Typical conditions for these types of harsh applications, include high temperatures, high pressures, erosive particulates in the fluid and multi-phase flow. The 74000 Series is designed as an optimized solution for process control under these combined conditions.

More Information

Selection Criteria

The 74000 Series is designed for severely erosive applications using 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 74000 Series is ideally suited to handle heavy oil processes typically found in resid-hydroprocessing and extremely erosive hydrocarbon process applications.

Key Features

The 74000 Series control valve features a rugged dual guiding system, ceramic or tungsten carbide trim, a fluted plug design and a flushing connection to prevent coking. This results in a highly stable operating control valve even under harsh service conditions, including high pressure, high temperature and erosive fluids.

Benefits

The 74000 Series control valve is designed with rugged top guiding to resist vibration associated with high pressure letdown or multi-phase service. The design features Masoneilan’s axial flow plug, which provides additional guiding for added stability and vibration resistance. High thrust and stiffness actuation further extends life in difficult applications.
