Linear Flow Control LFCLinear Flow Control LFC - DISCONTINUED

  • Replaced by Linear Flow Control model VFC
  • Linear behavior between adjustment angle and flow rate
  • Large control ratio of 25:1
  • Actuators IC 20 or IC 40 can be mounted without an adapter
  • For gas and air
  • Low leakage rates
  • High control accuracy
  • Compatible with MODULINE Series

Description

The linear flow control LFC adjusts volumes of gas and cold air on various systems. It controls ratios up to 1:25, and with the mounted actuator IC 20 or IC 40, it is suitable for regulating flow rates for modulating or stage-controlled combustion processes.

Application for Linear Flow Contrl LFC LFC, lambda control

If the burner is to be operated with different lambda values for process reasons, the linear flow control LFC can be used to correct the lambda value.
Application for Linear Flow Contrl LFC LFC, adjusting the burner output

In pneumatic systems the linear flow control with mounted actuator IC 20..E determines the air volume for the required burner output. The butterfly valve BVA/BVG with manual adjustment is used to adjust the high-fire rate.
Application for Linear Flow Contrl LFC Zone control

After initiating the burner control unit, the gas solenoid valve and the linear flow control LFC open. The burner is ignited by the burner control unit BCU. The gas flow rate can be adjusted continuously using the linear flow control with actuator IC 20. The air flow rate remains constant.
Application for Linear Flow Contrl LFC Excess air burner

After initiating the burner control unit, the linear flow control LFC moves to the ignition position. The burner is ignited by the burner control unit BCU. The gas flow rate can be adjusted continuously using the linear flow control with actuator IC 20. The air flow rate remains constant.
