Page 7 Operation Figure 3 shows the normally open valve in the open or full flow position and the normally closed valve in the closed or zero flow position. The valve spring provides the necessary force to hold the stem in the raised or normal position. In the event of power failure, a fail-safe actuator returns the valve to its normal position. Fail-in-place actuators will hold the last commanded position. See the Technical Instructions of the various actuators for additional information. Figure 3. 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 the seat and throttling plug can be damaged 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: water, etc. • 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 Application Bulletin (AB)-1 Control Valve Selection and Sizing (155-285) for further recommendations. See Tables 3 through 6 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. It is not recommended to install the valve assembly so that the actuator is below horizontal or upside down. Technical Instructions Powermite 599 Series MZ Series Zone Control Two-way Valves Document No. 155-198P25 December 29, 2009 Page 8 Siemens Industry, Inc. Mounting and Installation, Continued Allow sufficient space for servicing the valve and actuator. See Table 8 for valve body dimensions. See Figure 4 and Table 9 for dimensions of the service envelope recommended around the actuator. NOTE: Instructions for field mounting an actuator, wiring diagrams, and start-up are covered in the Technical Instructions and Installation Instructions for each actuator. Service Replace the valve if inoperable. Dimensions See Table 8 for valve body dimensions. The letters in Figure 4 refer to the valve centerline to top of the actuator, the width of the actuator, and service envelope dimensions in Table 9.
