Three-way ButterflyValve Sizing

Catalog 12Fisher, Fishtail, and Fisher-Rosemount are marks owned by Fisher Con-trols International, Inc. or Fisher-Rosemount Systems, Inc. All other marksare the property of their respective owners.

A three-way butterfly valve consists of two standard butter-fly valves mounted on a pipe tee. The valves are operatedby a single actuator through a tandem linkage. The linkageis normally arranged so that one of the valves is openingwhile the other is closing. For additional three-way butterflyvalve information, refer to Bulletin 51.4:020.

When sizing a three-way butterfly valve, the relationshipbetween valve disc rotation and flow must be kept in mind.With butterfly valves, this relationship is equal percentageand not linear. Due to this relationship, at mid--travel of thevalve disc, flow capacity is less than one-half total valve ca-pacity. With a three-way butterfly valve, one valve is open-ing while the other valve is closing, and both valves aremidway through total disc rotation of 60 or 90 degreeswhen the actuator is at mid-travel. The combined capacityof the two valves at mid-travel is less than wide-open ca-pacity of one valve.

Figure 1. Three-Way Valve Capacity with SingleActuator60-Degree Maximum Valve Disc Rotation

A1884-1

If each valve is sized to handle maximum pipe tee flow atfull disc rotation, combined capacity of the two valves atmid-travel will be lower than the flow capacity of the tee. Al-though this reduction is present at all points of travel, it ismost significant at mid-travel. This is illustrated in figures1 and 2 for conventional discs. For FishtailR discs, one-half of total valve capacity is reached at an even largerangle of disc rotation, and the reduction in combined ca-pacity at mid-travel is greater than it is with conventionaldiscs.

For flow-switching (on/off) applications, this is not serioussince the valves will be at mid-travel only momentarilywhile the valves are being stroked open and closed.

For throttling applications, it is possible that the valves willremain at mid-travel for significant periods of time. In theseapplications, the capacity reduction could cause system

problems such as compressor surging. To avoid theseproblems, size each valve to carry one-half of the maxi-mum pipe tee flow at mid-travel. Then, the combined flowcapacity of the two valvesatmid-travelwill equalmaximumflow.

If it is not desirable to do this, operate each valve with aseparate actuator and valve positioner. Use onedirect-act-ing and one reverse-acting positioner and adjust the posi-tioners for split-range operation. With this arrangement, asingle input signal will open onevalvewhile closing theoth-er. Since split-range operation is being used, the position-ers can be adjusted such that the mid-travel position of thedisc is reached before the input signal reaches mid-range.Then at mid-range of the input signal, each valve can be atone-half of total capacity, rather than at one-half of totaldisc rotation. A typical example is shown in figure 3. Al-though figure 3 illustrates the use of piston actuators withType 3570 positioners, a similar arrangement can bemadewith any actuator and positioner type. Contact the Fisherrepresentative for sizing assistance if dual actuation withsplit-range positioners is desired.
