SM100 and SM100R

Reversible rotary actuator

Application
The rotary actuator SM100 is best suited for the automation of mixing valves up to DN100 and they fit to valves manufactured by  EXCELSIOR BÜCHE, LANDIS AND GYR, ESBE and CENTRA  and also to other brands.
Mainly, however, the rotary actuator is used for the operation of ball valves in sizes DN15 to DN50 and used also equally for 2-way and 3-way valves, the latter in a horizontal or vertical design.

Function
The rotary drive SM100 is controlled by an electrical signal coming from a thermostat, remote control or manual switch.
Another possibility is the three-point control of an appropriate control device with the following outputs: OPEN – INACTIVE – CLOSE.
The model with relay (SM100R) is suitable to be controlled by an ON-OFF switch.

Optionally, the actuator will also be equipped with additional limit switches each having 2 clean relay contacts.
By default, the rotation angle of the rotary actuators is 90°, but there is also the possibility to enlarge the rotation angle to 180°.

The rotary actuator has a lever mounted on the actuator to allow to set the valve to the desired position without being connected to the power supply.
However, once the actuator is electrically connected he will find by himself the position set by the controller.

The optional model SM103 is equipped with additional electronics in order to be controlled by a variable voltage signal of 0 … 10 VDC.
Through an internal adjustment the input voltage range can be varied from  0 … 7 VDC to 2…19 VDC. Depending of the applied input signal the rotary actuator will be positioned accordingly
See datasheet SM103

Construction
The mechanical internal parts are all made of metal. The gearbox housing is made of aluminum and the gears are machined from steel and heat treated afterwards.
The case bottom and the housing cover are both made of tough self-extinguishing polycarbonate according to UL 94 VO.
Furthermore, on the bottom there are two cable glands PG9 mounded, made from self-extinguishing polyamide.
Optionally, the housing bottom will be equipped with a mounting flange according ISO 5211 F05 with a 11 mm square.
The rotary drive meets the requirements of the following standards:
– CEE 89/336-73/23-93/68
– UE 2002/95/EC
– UE 2002/96/EC (ROHS and WEEE)

Notes
The installation of the rotary actuator must be performed strictly by a qualified electrician according to local regulations. The ground terminal has also to be wired properly.
