Description
Belimo B211+LRB24-3 Overview
The Belimo B211+LRB24-3 is a factory-assembled 2-way valve and actuator combination engineered for reliable flow control in commercial HVAC hydronic systems. The assembly pairs the B211 characterized control valve body — featuring a close-off (CCv) flow characteristic, stainless steel trim, and 1/2″ NPT end connections — with the LRB24-3 non-spring-return rotary actuator, delivering a complete, ready-to-install solution.
