The PV02 series proportional valve is a small diameter series in Keyto's proportional valve . With a range of flow paths from 0.15 mm to 1.6 mm. The valve is suitable for precise flow control. The proportional valve controls the gas flow rate proportional to the input current, which can be controlled by adjustable DC current or pulse. The input current can be controlled by adjustable DC current or pulse width modulated current (PWM).
The proportional valve can be controlled in either open-loop or closed-loop mode, with flow or pressure sensors in the gas circuit for closed-loop control. or pressure sensor in the gas circuit for closed-loop control, the best control effect can be achieved.
