Retrofit Solutions

Valves and actuators are responsible for ensuring reliable functioning of HVAC systems all over the world. Damaged actuators or valves in a HVAC system used to create a large field issue. Replacing the valve along with the actuator is not always a sensible solution. Taking a system off-line to replace numerous valves is not only laborious, it’s expensive. Facilities can lose thousands of dollars a day during maintenance shut-down.

With Belimo retrofit solutions, these problems simply go away. Valves and actuators can be quickly and conveniently up fitted without any interruption in service.

Belimo Retrofit Linkages

Belimo globe valve actuators and retrofit linkages offer greater power and flexibility. Engineered to suit a broad range of HVAC applications, both the new generation actuators and retrofit linkages are highly adaptable making selection, installation, and long-term service worry-free. New force ranges from 112 lbf to 337 lbf and broader travel ranges from .6" (15 mm) to 2" (50 mm).


Adjustable Belimo FGVL Retrofit Linkage

Belimo's adjustable FGVL retrofit linkage fits on most 2½” to 6” globe valves offering quick and easy installation - conveniently up fitted without any interruption in service.

Belimo Jackshaft Linkage

The ZG-JSL linkage simplifies typical installations and eliminates the difficulties where jackshaft bearings are hard to access. The ZG-JSL linkage has a built-in shaft which allows the direct coupling of Belimo actuators. The anti-rotation plate enables the installed actuator to be rotated 90 degrees for space saving applications. By improving the method of installing actuators onto jackshafts, the installer saves on installation time translating into a cost savings.
