while the spring return provides a fail-safe closure in under 25 seconds

Belimo LRB120-SR Actuator Freon the Trane CNT2239 delivers aThe Belimo LRB120 SR is a high performance fail safe proportional actuator designed for the precise control of ball valves in HVACR systems. Operating on a universal 100 to 240 VAC power supply, this non spring return actuator delivers a consistent torque of 45 in lb (5 Nm), ensuring reliable modulation for B2 and B3 series pressure compensated valves. It utilizes a standard 2 to 10 VDC control signal or 4 to 20 mA with an external 500 ? resistor,
