he ASCO™ 314 Series is a versatile, direct-acting solenoid valve designed for reliable pilot flow control in small control valves and actuators. With a simple internal design featuring just one spring and two moving parts, it is an optimized, foundational 3-way, 2-position (3/2) valve suitable for a wide range of applications. Engineered for durability and efficiency, it operates reliably from zero pressure and offers long service life with minimal power consumption.
This compact and robust valve is ideal for use in analytical and diagnostic equipment, automotive systems, bottling lines, dust collector systems, and life science applications.
Simple & Reliable Design: The optimized 3/2 way design with minimal internal moving parts ensures consistent performance and reduces potential failure points.
True Zero-Pressure Operation: The direct-acting principle allows the valve to function reliably from vacuum conditions up to its maximum pressure rating, requiring no minimum operating pressure to start.
Durable Construction: Available in brass or stainless steel body materials for enhanced longevity and corrosion resistance in various environments.
Low Power & Wide Voltage: Features low power consumption and is available in a wide range of AC and DC voltage options, making it easy to integrate into different control systems.
Versatile Media Compatibility: Suitable for controlling air, inert gases, light oils, and water, providing flexibility for diverse applications.
Global Approvals for Hazardous Areas: The series offers solenoid coils with globally certified explosion-proof protection for use in hazardous locations.
