Masoneilan™ 80000 Series 3-Way Control Valve from VSI

Three-Way Control Valves Combining and Diverting Service

Masoneilan™ 80000 Series Features:

Heavy Guiding

• Construction of the Masoneilan 80000 Series includes top guiding in the plug and 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 stability 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 the 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 with 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 provide dynamic stability resulting in excellent process control and improved process yields. 
• Top and bottom entry access to the valve's 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.
