Belimo
The Belimo Linkage ZG-JSL is designed to facilitate the connection of EF spring return actuators to the junction shaft damper. The EF actuator uses rugged elements in a die-cast aluminum housing for added strength and reliability.
This system offers a large torque capacity of 270 (in-lb) and the NEMA 4 option to meet the harsh environmental conditions found in many HVAC applications. The unique design allows the Linkage to hold any part of a measuring junction shaft from 1/2" to 1.05" in diameter.
It simplifies normal installation and eliminates difficulties in the joint shaft bearings, which are so difficult to access. In addition, it has an integrated shaft that allows direct coupling of actuators and the anti-rotation plate allows the installed actuator to rotate 90° for space-saving applications.
