  Description

  The 80000 Series is a heavy duty three-way control valve designed for either combining or diverting service. Standard features include:

  Heavy Guiding

  Construction of the Masoneilan 80000 Series includes top guiding in the plug, as well as guiding within the seat ring locations providing an extremely well supported and stable design.

  High Capacity

  Large flow galleries in the 80000 Series provide high capacity designs with low pressure recoveries. High critical flow factors are attained in both combining and diverting configurations.

  Flow Stability

  The 80000 Series is a dual seated design with flow tending to open the valve at both ports. This provides inherent dynamic stable resulting in excellent throttling control performance.

  Wide Operating Range

  Designs are available in various sizes and can be configured to operate within an extremely wide temperature range. This is accomplished through use of high performance materials and design configurations.

  Reduced Emissions

  The 80000 Series can be supplied with the Masoneilan LE Packing design to provide low emissions performance meeting various environmental regulations worldwide.

  NACE Compliance

  Construction for Sour Service Applications in accordance with NACE standard MR 0103 is readily available. Applications requiring compliance to MR 0175, 2003 Rev or ISO 15156 can also be provided.

  • Large flow paths offer effective dirty service capabilities and high flow capacities. Heavy valve plug and stem guiding provides dynamic stability resulting in excellent process control and improved process yields. 
  • Top and bottom entry access to the valve internal components results in easy in-line access for maintenance and repair.
  • Extremely rugged design for reliable operation in demanding plant environments and process control applications.
