Single-Station Proportional Flow Control Valve

FC300-SG

Single-Station Proportional Flow Control Valve

The proportional flow control system combines a PM driver controller with an FC proportional flow valve. By receiving 0–10 V, 4–20 mA, or RS485 (Modbus) signals, the motor precisely adjusts the valve opening to achieve stable, linear, and accurate flow control for gases and liquids. Its responsive performance enhances equipment efficiency and precision.


To meet market needs for better protection and easier installation, we developed a new integrated enclosure version that unites the controller and valve body. This design maintains high-precision control while improving dust and splash resistance, making it ideal for long-term and demanding applications.
