ASCO JAPAN, Japan
ASCO Direct-Acting/Pilot-Acting Two-Way Proportional Control Solenoid Valve Posiflow
Made in Japan
Manufacturer: ASCO JAPAN Co.LTD.
Features
You can adjust the coil current easily through an external analog signal, with options including 0-10V, 4-20mA, or 0-20mA. The core moves to any desired position along the stroke, allowing precise control. By managing the orifice opening, you achieve stepless flow rate control from 0 to 100%. When combined with various sensors and control devices, this setup supports the automatic control of a wide range of equipment.
The electronic control unit for regulating coil current offers a compact, plug-in design, making it simple to integrate. You can select the control input signal from 0-10V (DC), 4-20mA, or 0-20mA. Additionally, the RAMP function smoothly adjusts the core control output current to handle sudden changes in the input signal, ensuring stable and efficient operation.
