74000 Series Key Features and Benefits

The base level 74000 series valve is characterized by a single stage trim, packaged in an angle style valve body, and having relatively simple flow geometry, for both the valve body and trim. This simplicity of flow path has proven successful in targeted heavy oil applications where high-velocity erosive jets are destroying more complex valve trims. This product has been uniquely successful in tough refining applications where entrained solids are the primary concern, and where other conventional severe service trims have failed catastrophically. The 74000 has industry-wide endorsements for success under the toughest of conditions, and is frequently specified by name with experienced users. When seeking products that are differentiated in the market, the 74000 stands out as unique in both design and performance.

The Masoneilan 74000 series valves serve a unique role in advanced oil refining operations:

  • Unique Severe Service Design  
  • Concentration of Entrained Solids and Process Catalysts
  • High Pressure Drop
  • High Velocity Erosive Flow
  • Process Outgassing
  • Longer Intervals Between Maintenance
