FlowCon SM DN15-250 (1/2”-10”) 09/2025 Fitting and Re-fitting the Actuator The suitable actuator types are all electrical programmable actuators: • SM.0.0.1.3 (standard) • SM.0.0.1.4 (standard failsafe) • SM.0.0.1.5 (BACnet) • SM.0.0.1.6 (BaCnet failsafe) It is recommended to grease the O-ring on the spindle adaptor with silicone grease before plac- ing the spindle adaptor on the valve spindle. Then place the actuator on the spindle adaptor and place the three actuator “legs” into the three holes in the mounting bracket (figure 2). Make sure that the snap ring is clicked onto the mount- ing bracket, so that the snap ring is locked at the top of the mounting bracket, but still able to rotate. Then finger-turn the snap ring counter clockwise (upside view) approximately 1/6 of a turn until its stop points touch the actuator “legs” and the mounting is locked with a (small) click. Do not use additional tools. Actuator legs Spindle adaptor Snap ring Figure 3 Do not remove cover from actuator. Opening cover will void warranty. Orientation Upside-down installation is allowed along with the standard horizontal and vertical installation (figure 4). 360º Figure 2 In case the actuator will have to be removed, it is recommended to electrically open the valve for easier removal. Hereafter reverse the procedure and turn the snap ring clockwise until the actu- ator is loosened and lift the actuator up. Again, no need for additional tools (figure 3).
