Masoneilan 80000 Series

3-way control Valve

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 meets NACE MR‑0103 (sour‑service), with MR‑0175/ISO 15156 options. Large flow paths handle dirty‑service with high capacity; heavy guides ensure precise control. Top/bottom entry eases maintenance. Rugged design guarantees reliability in harsh environments.
