Powermite 599 Technical Bulletin Document No. 155-306P25 TB 251 October 27, 2015 MT Series Terminal Unit Valve and Actuator Assembly Selection Siemens Industry, Inc. Description This Technical Bulletin aids in selecting a Powermite 599 Series MT Series terminal unit valve and actuator assembly. Figure 1 provides a graph of water capacity for selecting the proper valve size. Figures 2 through 5 show close-off pressures for selecting an actuator according to specifications. Tables 2 through 10 identify the product numbers. Table 1 provides a guide to these tables. The tables show all possible combinations of Powermite 599 Series valves and compatible actuators that can be ordered as complete valve assemblies from the factory. Tables 11 through 13 provide the dimensions of all valves and the service envelope required for each actuator. Using the Valve and Actuator Selection Graphs Use Figure 1, the water capacity graph, to select a valve size as follows: 1. Locate the specified flow rate on the vertical axis. 2. Follow across on the horizontal axis to the point of intersection with the specified pressure drop. 3. Choose the valve size from the heavy diagonal lines across the graph. Use Figures 2 through 5, the close-off pressure graphs, to select an actuator as follows: 1. Choose the graph for the valve action (normally open or closed) and actuator power source (electronic or pneumatic) specified. 2. Locate the bar that represents the valve size. The top of the bar indicates the maximum close-off pressure for tight close off. Use the legend at the bottom of the graph to identify the actuator. Using the Valve and Actuator Assembly Tables Use Tables 2 through 10 to select a valve and actuator assembly as follows: 1. Locate the appropriate table based on the required valve type, valve action, and actuator type per Table 1. 2. Read Tables 2 through 10 from left to right and select the appropriate valve specifications to identify the row with the required valve body. 3. Read across the top of the table and select the appropriate actuator specifications to identify the column with the required actuator. 4. Read down the actuator column and read across the valve body row. The column/row intersection determines the appropriate valve and actuator assembly. The valve and actuator assembly product number is the actuator prefix code added to the valve body suffix. Technical Bulletin MT Series Terminal Unit Valve and Actuator Assembly Selection Document Number 155-306P25 October 27, 2015 Page 2 Siemens Industry, Inc. Selection Example Specifications In an ANSI 250 piping system, a two-way, normally closed (NC), female-by-female (F×F) NPT threaded valve is to 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. The actuator is to receive 24 Vac power, supply a floating control signal, and provide spring return (SR) operation. The actuator is to close off tightly against a pump head pressure of 15 psi (103 kPa, 1 bar). Valve Sizing Use Figure 1, the water capacity graph, to select the valve size as follows: 1. Locate the required flow rate by finding 20 gpm (4.5 m3/h) on the vertical axis. 2. Follow across the horizontal axis to find the 5 psi (35 kPa) maximum allowable pressure drop across the open valve. 3. Since the point of intersection is near a 1-inch (25-mm), 10 Cv (8.5 Kvs) valve size, select that valve size to ensure proper flow. Actuator Selection Use Figure 2, the maximum close-off pressure graph for actuators on two-way valves, to select an actuator as follows: 1. For NC valves with electronic actuators, choose the upper left graph. 2. Locate the 3/4-inch to 1-inch bar to correspond to the 1-inch (25-mm) valve size. Note that the top of the bar or the maximum close-off pressure is 40 psi (276 kPa). 3. The 40 psi (276 kPa) close-off rating of the SAS Series actuator will close-off tightly against a pump head pressure of 15 psi (103 kPa, 1 bar). Assembly (Product Number) Selection Use Table 3, two-way normally-closed valve assemblies, to select a valve and actuator assembly as follows: 1. Read the table from left to right and select bronze trim for the low pressure, chilled water application; and F×F for NPT valve threads. Select a 10 Cv (8.5 Kvs), 1-inch (25-mm) valve size, determined from the preceding valve sizing example. The valve body part number is 599-02014. 2. Read across the top of the table and select a 24 Vac actuator with floating control signal and spring return (SR) operation. The actuator part number is SAS81.33U. The actuator prefix code number is 366. 3. Read down the SAS81.33U actuator column and across the 599-02014 valve body row. The column/row intersection determines the appropriate valve and actuator assembly, which is 366-02014. The valve and actuator can be ordered separately by using the part numbers from steps 2 and 3.
