Belimo ZDB-TF Rotation Limiter Designed for larger direct-acting andThe Belimo ZDB TF Rotation Limiter is a critical mechanical accessory for technicians requiring precise field adjustment of the stroke on Belimo TF Series actuators. Engineered for mechanical angle of rotation limiting, this galvanised steel component allows you to restrict the actuator's travel when the full 95 stroke is not required for specific damper or valve applications. By utilizing the built in end stop, contractors can set defined limits
