If other actuator types are required, consult Halton in order to specify the type and manufacturer.
Actuator installation on the site is possible with the help of an actuator bed and extension shaft. This enables installation of a universal actuator type. The actuator bed selected can be of standard type when the ductwork is not insulated or of high type if the ductwork is insulated.

The Halton PTS unit can operate as a shut-off, control or adjustment damper depending on the product model. This damper is available for circular standard duct sizes 100 mm to 500 mm. Damper position is visually indicated below the operating mechanism.
The Halton PTS/A is a shut-off damper of leakage class 4 according to the EN 1751 standard. It includes rubber gaskets to ensure low leakage flow when the damper is in closed position. The PTS/A is available with a handle for manual operation or with an electric actuator for on-off control or for modulating control using a 0…10 VDC control signal.
The Halton PTS/B can be used for airflow control or adjustment of airflow rates in the ductwork. It includes a steel blade without gasket. The PTS/B is available with a handle for manual operation or with an electric actuator for on-off control or for modulating control using a 0…10 VDC control signal.
The Halton PTS/C is an airflow adjustment damper. The damper blade is a perforated blade that is acoustically and operationally designed for balancing of airflow rates.
The electric actuator is normally installed in the factory on the actuator platform with screws. On-site actuator installation is possible with the help of an actuator installation kit. The actuator installation kit, available as an accessory, includes an actuator platform and extension shaft for universal actuator fixing. The actuator platform and actuator can be installed easily using standard hand tools.
Fasten the damper to the ductwork with, e.g., rivets. Ensure that the rivets do not prevent the operation of the damper. The position of each rivet must be at least 10 mm from the duct end.
External duct gaskets ensure an airtight joint when the damper has been mechanically fastened to the duct with rivets or screws.
The electric actuator (where applicable) is to be connected to the power supply and control signal wires according to the wiring diagram. Examples of connections for the standard actuators are shown in a separate diagram.
The electric actuator can also be installed, when necessary, in an on-site procedure with the help of an actuator platform and universal shaft fitting, available as an accessory:
Remove the operating mechanism (1) by opening the locking screw.
Assemble the actuator platform in the location of the operation mechanism (2) and ensure its stability mechanically by bending the legs of the actuator platform with a hand tool.
The universal actuator fitting enables connection of most actuator types to the shaft (3) (4).
Wire connections are to be performed according to the instruction for the actuator installed.
The casing and circular (perforated) blade of the shut-off / adjustment / control damper shall be made of galvanised steel.
The shut-off damper shall meet EN 1751, Class 4 tightness requirements.
External rubber gaskets on the spigot shall provide an airtight connection to circular ductwork.
