Powermite 599 Series Technical Bulletin Document No. 155-307P25 TB 252 February 9, 2018 MZ Series Zone Control Valve and Actuator Assembly Selection Siemens Industry, Inc. Description This Technical Bulletin will aid in selecting a Powermite 599 MZ Series zone control valve and actuator assembly. Begin with the graph of water capacity and the chart of close-off pressures to select a valve and actuator according to specifications. Use Table 1 to identify product numbers. Table 1 shows all the possible combinations of the Powermite 599 Series valves and compatible actuators that can be ordered as complete valve assemblies from the factory. The dimensions of all valves and the service envelope required for each actuator are included in Tables 2 through 4. How To Use The Selection Graphs Use Figure 1, the water capacity graph, to select a valve. Locate the specified flow rate on the vertical axis. Follow across on the horizontal line to the point of intersection with the specified pressure drop. Chose the valve size from the heavy diagonal lines across the graph. Use Figure 2, the close-off pressure graphs, to select an actuator. First locate the graph for the valve action specified. Locate the bar that represents the valve line size. The top of the bar indicates the maximum close-off pressure for tight close-off. How To Use The Valve Tables Table 1 has been organized to help select a valve and actuator combination using additional specifications. Moving from left to right, identify the valve assembly needed. Continue to the right to match the valve to a desired actuator. A valve and actuator assembly part number is determined by combining the actuator prefix code with the suffix of the valve product number. No valve will combine with all actuators. The symbol “—” indicates a combination that is a special order. A shaded space indicates an inappropriate combination. Selection Example Select a two-way, normally closed, female by female NPT threaded valve and actuator assembly for an ANSI 250 piping system that will deliver 20 gpm (4.5 m 3 / h) chilled water with no more than 5 psi (35 kPa) pressure drop across the fully open valve. Specification The valve shall be operated by a 24 Vac powered, three-position control signal, fail-in- place electronic actuator, and must close off tightly against a pump head pressure of 15 psi (1 bar).Technical Bulletin Document No. 155-307P25 February 9, 2018 Page 2Siemens Industry, Inc. Valve Sizing Use Figure 1, the water capacity graph, to begin valve sizing. 1. Locate 20 gpm (4.5 m 3 /h) on the vertical axis to find the required flow. 2. Read across the horizontal axis to find 5 psi (35 kPa), the maximum allowable pressure drop across the open valve. Select a 1-inch (25 mm) 10 Cv (8.5 Kvs) line size valve because the point of intersection falls close to the 1-inch line. Actuator Selection Use Figure 2, the close-off pressure graph for actuators on two way valves, to choose an actuator. 1. Locate the graph for the actuator on a two-way, NC valve in the upper left of the figure. 2. Locate the bar for 3/4 to 1-inch valves. Notice that SSB… has the sufficient force to provide tight close-off against more than 15 psi (1 bar) differential. Product Number Selection Use Table 1. Begin at the left and select the specifications necessary. 1. Select a two-way, normally closed, and FxF for female by female NPT threads, according to the specifications. 2. Select the 1-inch line size determined from the sizing example above. 3. The valve part number is 599-01114. 4. Read across the top of the table to Electronic-mechanical, 24 Vac, 3P control signal. 5. The actuator part number is SSB81U. 6. The actuator code number is 254. 7. Read down the column to determine the valve and actuator assembly product number is 254-01114. NOTE:The valve and actuator can be ordered separately by using the part numbers from steps 2 and 3. Disposal The actuators are considered electrical and electronic equipment for disposal in terms of the applicable European Directive and may not be disposed of as domestic garbage. • Dispose of the actuators through channels provided for this purpose. • Comply with all local and currently applicable laws and regulations. Do not dispose of valves as household waste. • Special handling of individual components may be mandated by law or make ecological sense. • Observe all local and currently applicable laws and regulations.Powermite 599 MZ Series Zone Control Valve and Actuator Assembly SelectionTechnical Bulletin 155-307P25 February 9, 2018 Siemens Industry, Inc.Page 3 Figure 1.
