Belimo LRB120-SR Actuator 320819-301 it is recommended to replace

it is recommended to replace the element when the pressure drop reaches 10 psid or at least every 12 months to avoid potential contaminant carryover

Rotation is easily reversed via the lead connections

or clogged ports that can cause erratic burner behavior or failed flame sensing

If the furnace is tripping a pressure switch code but the tubing is clear

Belimo LRB120-SR Actuator 320819-301 it is recommended to replaceThe 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,
