Document No. 155-36P25 TB 251 August 9, 212 Powermite 599 MT Series Terminal Unit and Actuator Assembly Selection 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 1 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 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 and Actuator Assembly Tables Use Tables 2 through 1 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 1 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.
Document Number 155-36P25 August 9, 212 MT Series Terminal Unit and Actuator Assembly Selection Selection Example Specifications In an ANSI 25 piping system, a two-way, normally closed (NC), female-by-female (F F) NPT threaded valve is to deliver 2 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 non-spring return (NSR) operation. The actuator is to close off tightly against a pump head pressure of 15 psi (13 kpa, 1 bar). Sizing Actuator Selection Assembly (Product Number) Selection Use Figure 1, the water capacity graph, to select the valve size as follows: 1. Locate the required flow rate by finding 2 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), 1 Cv (8.5 Kvs) valve size, select that valve size to ensure proper flow. 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 4 psi ( kpa). 3. The 4 psi ( kpa) close-off rating of the SQS series actuator will close-off tightly against a pump head pressure of 15 psi (13 kpa, 1 bar). 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 1 Cv (8.5 Kvs), 1-inch (25-mm) valve size, determined from the preceding valve sizing example. The valve body part number is 599-214. 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 SQS85.53U. The actuator prefix code number is 266. 3. Read down the SQS85.53U actuator column and across the 599-214 valve body row. The column/row intersection determines the appropriate valve and actuator assembly, which is 266-214. The valve and actuator can be ordered separately by using the part numbers from steps 2 and 3.
