IVAR.SERVOPOHON-L actuator for IVAR.TV3-300 boiler modules DN 40 – DN 65 – 24 V DC, 0–10 V, 20 Nm
Code: IVA20317351Related products
Product detailed description
The IVAR.SERVOPOHON-L actuator, code IVA20317351, operates the 3-way mixing valve of IVAR.TV3-300 boiler modules sized DN 40, DN 50 and DN 65 in heating and air-conditioning systems. It is driven by a 24 V DC motor, and the internal electronics set the valve position according to a continuous 0–10 V signal.
Adapting to the system
- input signal 0–10 V DC as factory default, changeable to 2–10 V DC with jumper ST2
- direction of rotation selected with jumper ST1
- rotation angle electronically limited to 90° and adjustable – start point within 0–60°, end point within 60–120°
- potentiometer K changes the actuator characteristic continuously from convex through linear (factory setting) to concave
Data and operation
- 20 Nm torque, 100 mA current draw, IP 54 protection
- operating temperature 2 – 110 °C, ambient temperature 0 – 40 °C
- PC thermoplastic housing, 133 × 146 mm, weight 1.5 kg
If the rated torque is exceeded, the actuator switches itself off. It is maintenance-free and can be moved with the manual lever after pressing the clutch button. Wiring may only be done by a person with electrical qualifications. The 230 V version with 3-point control has the code IVA20317350.

Frequently asked questions
What control signal does the IVAR.SERVOPOHON-L actuator accept?
It is factory-set to a continuous 0–10 V DC signal and can be switched to 2–10 V DC with jumper ST2.
Can the rotation angle be limited?
Yes, the start point is set with potentiometer PL within 0–60° and the end point with potentiometer PR within 60–120°. The nominal 90° angle is set at the factory.
Which boiler modules is the actuator designed for?
For IVAR.TV3-300 boiler modules with a 3-way mixing valve in sizes DN 40, DN 50 and DN 65.
Does the actuator need maintenance?
No, the actuator is maintenance-free. Its electronics protect it against overload by switching it off when the rated torque is exceeded.

Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
