THREE-WAY SEATED GLOBE CONTROL VALVE - SERIES 30,31&32
THREE-WAY SEATED GLOBE CONTROL VALVE
SERIES 30, 31 & 32
Our Series 30, 31 and 32 range of three-way mixing and diverting valves allow for accurate controlled splitting or mixing of flows even at high flow capacity. They are based on the body design of our Series 10 range and are primarily used for blending of flows. When used in reverse they can also be used to split flows. They come in sizes 1.5” to 12” (40mm to 300mm) and an ASME rating of 150-600.
TECHNICAL SPECIFICATION
SIZES: 1.5” to 12” (40mm to 300mm)
RATINGS: ASME 150-600
TRIM OPTIONS
SERIES 30A
MIXING (BLENDING)
When used for mixing, the Series 30 valves have two separate inlets and one common outlet. Flows are proportionally blended into one stream by control of the valve plug position. The standard plug – a linear ‘V’ port – provides a high flow capacity and high rangeability.
SERIES 30B
SPLITTING (DIVERTING)
When flowed in reverse the Series 30 valves can be used for splitting flows. Here, the valve has one common inlet and the flow is split proportionally between two outlets. The total outlet capacity is constant, irrespective of the plug position.
SERIES 31
SPLITTING (DIVERTING)
Based on the Series 20 design, the Series 31 has an additional body rib inserted to separate flows. The under/over flow regime means the plug is inherently balanced, so that the valve requires a smaller actuator than an equivalent Series 30.
SERIES 32
SPLITTING (DIVERTING)
Based on the Series 10 body casting, the Series 32 has a bottom flange fitted to the base of the body as an inlet connection. The trim is cage guided with a balanced plug. Depending on the plug position, flow is proportionally directed to the left or right-hand outlet.
OTHER FEATURES
FULL RANGE
OTHER FEATURES OF OUR THREE-WAY SEATED GLOBE CONTROL VALVE:
- Offers proportional splitting or mixing of flows.
- Balanced trim construction allows for high flow rates while minimising actuator size.
- Minimum differential plug areas reduce actuator force requirements (Series 31 & 32).
- Excellent flow control rangeability.
