Description
The Belimo B318+TFRB24-SR 3/4″ 3-Way Spring Return Characterized Control Valve Actuator is a 24V modulating valve assembly with a 210 VDC control signal, 22 lb-in torque, and a 7.4 Cv flow capacity for accurate hydronic flow regulation. It is installed in HVAC systems to manage the movement of hot or chilled water through coils, air handlers, terminal units and other piping circuits. The mechanism automatically moves the valve to its preset position during power loss, while the actuator continuously adjusts valve position to maintain stable temperature control and efficient system operation.
