BELIMO RobustLine: actuators for demanding conditions

RobustLine actuators

Corrosion-resistant and completely sealed

Guaranteed enclosure protection rating IP66/67

In locations particularly exposed to external factors, actuators mounted directly on control elements often operate in extremely harsh conditions. Aggressive gases, moisture, heavy dust and dirt, as well as low temperatures and ultraviolet radiation, reduce the device's service life. For this reason, Belimo developed RobustLine actuators. Thanks to their highly durable housing with an IP66/67 protection rating, they meet the highest requirements.

Ideal for extreme environmental conditions

In animal husbandry, as well as in buildings with swimming pools, agriculture, food processing and rooftop installations, Belimo RobustLine actuators remain corrosion-resistant and fully sealed, even in the harshest environmental conditions. Terminals made of stainless and acid-resistant steel or form-fit connectors made of high-grade aluminium guarantee ideal power transmission – for both air dampers and valves. There is also space inside the housing to install additional equipment, such as a relay or controller.

Reliability and long service life

RobustLine actuators are available in versions for dampers and for ball control valves and butterfly valves. In addition to open/close and analogue types, we also offer programmable versions. If required, the actuators can be factory-fitted with a heater and thermostat. This means they can be used at low temperatures down to -40°C. Alternatively, the heating element can be connected to a hygrostat. This solution ensures reliable operation and a long service life when the actuator is exposed to strong temperature fluctuations and very high humidity. Ideal
