Direct-acting and pilot-operated flow proportional control solenoid valve / Japan Asco
Proportional valves are cheaper than control valves and achieve faster response times compared to electric valves!
We offer a compact and high-precision "Direct-Acting Pilot Type Flow Proportional Control Solenoid Valve." When current is applied to the coil, the core is attracted to the coil by electromagnetic force. As the current value changes, the attracting force also changes proportionally. The core displaces based on the balance between this attracting force and the spring load, allowing for flow control. We have a lineup of "proportional valves" and "control units." 【Features of the Proportional Valve】 ■ Flow can be controlled continuously from 0 to 100% using input control signals of 0-10V, 4-20mA, or 0-20mA (when using the control unit). ■ Compact size that does not take up space, similar to a solenoid valve. ■ A wide range of flow options available. ■ Options for gases (air, gas) and liquids (water, oil) are selectable, accommodating various fluids through choices of body material and seal material. *For more details, please download the PDF or feel free to contact us.
basic information
【Features of the Control Unit】 ■ Can be directly assembled onto the coil (depending on the product) ■ Outputs power to the coil by pulse width modulation (PWM) according to the control signal ■ Monitors current values and adjusts for changes in temperature and supply voltage to maintain a constant output *For more details, please download the PDF or feel free to contact us.
