Determine the valves required output torque in Nm. 2. Select the appropriate Input/Output table to use. This will be determined by the application. Normal Industrial: Allows for higher input torques/rim pull efforts. Severe Industrial/Public Authority: Is typically for municipal use where there is a maximum limit of 60 Nm input torque or 135 N rim pull effort. 3. Search through the table and find a torque value equal to, or greater than the valves required output torque. 4. Following that column vertical upwards gives the Input Torque, Rim pull Effort and Handwheel Diameter. 5. Ensure that these are within the required sizing parameters. 6. Following horizontally across from the torque value, to find which gear operator to use. 7. Check the shaft size is suitable for the unit. Selection procedure Should you need to select an actuator outside the parameters of the selection guide shown overleaf, use one of the following methods: Based on allowable input torque: 1. Determine the valves required output torque. 2. Select an actuator from the technical data s maximum torque output column. 3. Check the shaft size is suitable for the unit. 4. Divide the output torque by the selected actuator s mechanical advantage to give the actual input torque. Example: DN 300 F631 DIHI AS 2129 F Operating pressure 2100 kpa Required output torque: = 1075 Nm Maximum allowable input torque: = 60 Nm Shaft size: = 11 8 Select K26S3 rated at 3300 Nm. Check shaft size 21 4 is standard bore diameter therfore O.K. Calculate actual input torque = 1075 27.5 Actual input torque = 39 Nm < 60 Nm therfore O.K. Based on allowable rimpull effort: 1. Determine the valves require output torque. 2. Select the actuator from the technical data s maximum torque output column. 3. Check the shaft size is suitable. 4. Choose a handwheel diameter from the standard available diameters. 5. Calculate the desired mechanical advantage by dividing the output torque by the selected unit s rim pull and multiply by the handwheel radius. 6. From the technical data, select the unit that has the nearest mechanical advantage. 7. Using the selected units mechanical advantage, calculate the actual rim pull effort. Example: DN 600 F631 DIH1 AS 2129 F Operating pressure 2100 kpa Output torque: = 3680 Nm Maximum allowable rimpull effort: = 400 N Shaft size: = 21 4 Select K40S3 rated at 5500 Nm. Check shaft size 21 4 is standard bore diameter therefore O.K. Choose a handwheel diameter of 450mm. Calculate desired mechanical advantage. = 3680 400 x 0.225 MA = 40.8 F427 K40S3 450 mechanical advantage = 45.8 > 40.8 O.K. Calculate the actual rimpull effort = 3680 45.8 x 0.225 Actual rimpull effort = 357 N < 400 Selected actuator is F427 K40S3 450. Selected actuator is F427 K26S3. 4

Waterworks valves actuator sizing is based on 2100 kpa working pressure and an input torque of 60 Nm or 135 N rim pull. The K-LOK (F360/F362) valve sizing is based on RTFE seated valves only, and at their maximum pressure rating of 5100 kpa. For all other trims refer to the sizing table over page. Select the column of the valve type you want to actuate ie GRW. Look down that column to the valve size required. Follow that line horizontally across to the left for the most suitable actuator to use. Refer to the Adaptability chart literature sheet to establish whether Bosses are required to adapt the valve and actuator. 6
