Belimo ZDB-LF Rotation Limiter Drop-in Compatibility: Specifically designed as

Drop-in Compatibility: Specifically designed as the updated technical successor to the legacy DMPR-RS202 model

This process significantly reduces stack temperatures and lowers fuel consumption without requiring a full system overhaul

meaning it re-closes the circuit on its own once temperatures drop

Direct Compatibility: Engineered specifically for the Johnson Controls T-4000 series horizontal thermostats

Belimo ZDB-LF Rotation Limiter Drop-in Compatibility: Specifically designed asThe Belimo ZDB LF Angle of Rotation Limiter is a field installable accessory designed specifically for the LF series spring return actuators. This mechanical stop allows technicians to precisely calibrate the stroke of the actuator when the application requires less than the standard 90 degree rotation. Constructed from durable, corrosion resistant materials, the ZDB LF ensures long term reliability in demanding HVACR environments. It is essential for
