Operation 2-Way Figure 3 shows the zone valve in the open or full flow position. The valve spring provides the necessary force to hold the stem in the raised or NO position. In the event of power failure, the actuator returns to its normal position; the actuator determines whether the valve will fail open or closed. See the actuator Technical Instructions for additional information. Figure 3. 3-Way Diverting As the valve stem moves downward, the flow through the NO port (AB-A) decreases and the flow through the NC port (AB-B) increases. As the valve stem moves upward, the flow through the NO port (AB-A) increases and the flow through the NC (AB-B) port decreases. In the event of power failure, the actuator returns the valve to its normal position; the actuator determines whether the valve fails with flow to port A or port B. See the actuator Technical Instructions for additional information. Figure 4. Mixing The 3-way zone valves are diverting valves. However, they may be used as mixing valves under the conditions shown in Figures 5 and 6. Figure 5.

Allowable Differential Pressure in Relation to the System Pressure. Sizing The sizing of a valve is important for correct system operation. An undersized valve will not have sufficient capacity at maximum load. An oversized valve can initiate cycling and can damage the seat and throttling plug because of the restricted opening. Correct sizing of the control valve for actual expected conditions is considered essential for good control. The following variables must be determined: • The medium to be controlled: hot or chilled water. • The maximum inlet temperature and pressure of the medium at the valve. • The pressure differential that will exist across the valve under maximum load demand. • The maximum capacity the valve must deliver. • The maximum line pressure differential the valve actuator must close against. See Control Valve Selection and Sizing Application Bulletin (140-0038) for further recommendations. See Table 3 and Table 4 for valve capacities. Mounting and Installation Install the valve so that the flow follows the direction of the arrow indicated on the valve body. For best performance, install the valve assembly with the actuator above the valve body. The valve and actuator can be installed in any position between vertical and horizontal. NOTE: It is not recommended to install the valve assembly so that the actuator is below horizontal or upside down. Allow sufficient space for servicing the valve and actuator. See Table 5 for valve body dimensions. NOTE: Instructions for field mounting an actuator, wiring diagrams, and start-up are covered in the Technical Instructions for each actuator.
