Safety notes
!
• The actuator has been designed for use in stationary heating, ventilation and air conditioning
systems and is not allowed to be used outside the specified field of application, especially in
aircraft or in any other airborne means of transport.
• It may only be installed by suitably trained personnel.
Any legal regulations or regulations issued by authorities must be observed during
assembly.
• The device may only be opened at the manufacturer's site. It does not contain any parts that
can be replaced or repaired by the user.
• The device contains electrical and electronic components and is not allowed to be disposed
of as household refuse. All locally valid regulations and requirements must be observed.
• The switch for changing the direction of rotation may only be operated by trained personnel.
The direction of rotation may not be changed with frost protection circuit.

TRY24-SR Rotary actuator AC/DC 24 V, 2 Nm
2 / 2 T5-TRY24-SR • en • v1.1 • 05.2010 • Subject to changes www.belimo.com
Product features
Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the
position dened by the control signal.
Simple direct mounting Straightforward direct mounting on the ball valve with only one screw. The mounting position in
relation to the ball valve can be selected in 90° steps.
Manual override Manual operation with lever possible (the gearing is disengaged for as long as the self-resetting
lever is pressed).
High functional reliability The actuator is overload-proof and automatically stops when the end stop is reached.
The actuator switches off for seven seconds in the case of blocking, then attempts to restart. If
the blocked condition persists, the actuator attempts to restart once every two minutes a total of
15 times and subsequently once every two hours.
Combination valve actuators Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.

• Data sheets for ball valves
• Installation instructions for actuators or ball valves, respectively
• Notes for project planning (hydraulic characteristic curves and circuits, installation regulations,
commissioning, maintenance, etc.)
