ASCO Proportional Control Air Operated Valve
Made in Japan
Manufacturer: ASCO JAPAN Co.LTD.
This is a two-way valve operated by air, capable of controlling the flow rate in proportion to the control signal. It can regulate the flow of air, general fluids, and corrosive liquids. With its compact design and ease of use, the valve is highly convenient. By using dedicated software, users can also perform feedback control and make parameter adjustments seamlessly.
Features
The valve controls flow proportional to the control signal and allows for feedback control when using external sensors. It includes an LED indicator, making it easy to check the valve’s open or close status at a glance. Designed for outdoor use with an IP66 rating, the valve also offers the option of fail-safe operation for added safety. It features a 2-way piston design, normally closed (NC) with under-disk pressure type, and is available in operator diameters ranging from 63mm to 125mm. Additionally, users can choose between cable gland or M12 type wiring connections, depending on their preference.Wiring connection can be selected as cable gland type or M12 type
Application Examples
Adjustment of the flow rate of burner combustion gas
