Belimo valves and actuators set the global standard for quality and ease of use.  Their simple design finds these products in factories and commercial facilities wordwide.  Since 1975, Belimo has been providing keen energy efficient solutions for the heating, ventilation, and air conditioning markets.

Valve selection should be done in accordance with the flow parameters and system specifications. The actuator is mounted directly to the valve without the need for tools or additional linkage. Damper torque loadings, used in selecting the correct size actuator, should be provided by the damper manufacturer. Belimo actuators should be mounted indoors in a dry, relatively clean environment free from corrosive fumes. If the actuator is to be mounted outdoors, a protective enclosure must be used to shield the actuator. For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting and service of the Belimo actuator on the shaft. 

The actuator/damper installation may be tested without power at the actuator. Refer to the manual positioning section of the instructions. Move the damper to its full non-fail-safe position using the manual crank. Disengage the manual position mechanism and have the damper go to full fail-safe position.
