  • Page 2: General Features

    ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 1) GENERAL FEATURES KSB manufacture a wide range of part turn pneumatic actuators for valve remote control. The actuators are available on Double Acting “ACTAIR NG” and Spring Return “DYNACTAIR NG” versions. - The principle of the actuator application is to open and close the connected valve, without the manual operation with lever or hand wheel, by means of an electric-pneumatic connection on remote control.
  • Page 3 ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 f) Cycle time. The cycle time is dependent on different operating and installation factors such as the supply pressure, the flow capacity, the connection pipe size, the solenoid valve performance, the valve torque and characteristics, environmental temperature condition Actuator opening, closing and open/close cycle times (sec.).
  • Page 4 ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 For aggressive atmosphere and severe environmental condition select the required protection from the external finishes please contact KSB. l) Marking and classification All KSB actuators bodies are marked with the Manufacturer name and address, the actuator Type code including the Series and Size, and its range of Pressure and Temperatures working conditions and limits.
  • Page 5 ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 3) OPERATION AND ROTATION DIRECTION Double Acting. The pistons of standard ACTAIR NG actuators are mounted as shown below. This provides the highest torque at the valve start opening for valve clockwise to close. The pistons are then in their outermost position and the end travel stops can be fine adjusted.
  • Page 6 ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 Double Acting operation cycle (ACTAIR NG Type). Simple Acting Spring Return fail to close operation cycle (DYNACTAIR NG Type) Actuator operation functionality remote control should be done by means of direct solenoid valve connection to the actuator standard interface VDE/VDI 3845 NAMUR, or by means of pipes screwed on the ports marked with the numbers 2 and 4 and connected to a separate control cabinet.

  • Page 7: Rotation Direction

    ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 Fig 3.1 – Typical air connection schema A) Rotation direction In accordance with the international standard ISO 5599-2 the actuator air ports connection position, location, orientation and form shall be clearly identified and marked with the numerate 2 and 4. Standard Double Acting and Simple Acting Spring Return actuators shall be Clockwise (CW) direction to valve Close, and Counter Clockwise (CCW) direction to valve Open.

  • Page 8: Installation Instructions

    ACTAIR - NG2 to NG160 INSTRUCTION MANUAL DYNACTAIR – NG1 to NG80 5) INSTALLATION INSTRUCTIONS The principle of the actuator application is to open and close the connected part turn valve installed in a plant, without the manual operation, by remote control by means of an electric-pneumatic connection. The normal sizing of actuators requires a 20%-30% safety margin over the valve breakaway torque to handle valves.
