The ASCO™ 223 Series is a line of robust pilot-operated solenoid valves engineered specifically for high-pressure applications. Designed with a unique stainless steel piston construction, this durable valve is built to handle high-flow pressures of up to 100 bar, ensuring reliable performance in demanding conditions. Its versatile design supports a wide range of media, making it a dependable solution for air, water, light oil, and inert gas control in various industrial and commercial settings.
Multi-Media & Material Versatility: Effectively handles air, inert gas, water, and light oil. Available with brass or stainless steel body options, providing corrosion resistance for different environments.
Compact & Service-Friendly Design: The space-saving design allows for easy integration into tight spaces. Features like a removable coil and accessible internal parts simplify inspection and service, reducing downtime.
Flexible Installation & Control: Can be installed in any position for layout flexibility. Offered in both Normally Closed (NC) and Normally Open (NO) configurations to suit various control logic requirements.
Enhanced Function Options: Multiple variants are available to meet specific needs, including models with water hammer suppression for water lines, designs for oxygen service, and versions certified for use in hazardous areas (ATEX, WRAS). The valves do not require a minimum working pressure differential to operate, ensuring reliable performance from start-up.
Global Standard Compliance: Coils come standard with a DIN plug connection and are available in a wide range of AC and DC voltages to meet international electrical standards.
