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.

1) .75” & 1” (20 & 25mm) sizes are not available in the 80386 diverting configuration.
Utilize combining version 80385 and consult factory for details.
2) Maximum temperature shown is with PTFE and LE packing. Extended max. operating temperature of 800°F (427°C)
allowable with Graphite packing.
3) Class II shutoff is standard leakage rating. Class III and IV can be provided depending on application service conditions.
Consult with factory on Class III and IV applications and requirements.
4) LE Packing for low emissions applications is limited to maximum pressure and temperature as shown in chart below.
1) Use spring-diaphragm actuator Model 37/38 for 12” (300 mm) valve size.
