ASCO 8214250CSA-24V Solenoid Valve

The ASCO 8214250CSA-24V is a high-performance, 2-way normally closed gas shutoff solenoid valve engineered for critical combustion system safety. Designed for a 1-inch pipe size with flexible NPT or flange connections, this valve manages impressive flow rates of up to 1,132,300 BTU/hr with a 21 Cv flow coefficient. Operating on a 24Vac power supply, it is specifically optimized for low-pressure fuel gas shutoff applications ranging from 0 to 5 PSI. The rugged aluminum body and NBR seals ensure durable performance in demanding commercial and industrial environments, while the NEMA 1 enclosure provides essential protection for the electrical components. This ASCO Series 8214 valve is a trusted solution for managing natural gas or propane lines in boilers, furnaces, and industrial burners where reliable, leak-tight closure is a non-negotiable safety requirement.

Key Benefits

• Redundant Safety: Features a unique double-disc design with overtravel to ensure a leak-tight seal in the closed position.
• High Flow Capacity: Delivers a substantial 1,132,300 BTU/hr capacity, making it suitable for large-scale industrial heating equipment.
• Durable Construction: Built with a die-cast aluminum body and nitrile (NBR) elastomers for maximum resistance to fuel gas chemical profiles.
• Versatile Installation: Supports both NPT threaded and flange mounting options to simplify integration into existing gas trains.
• Low Pressure Optimized: Specifically rated for 0-5 PSI, providing precise control without the need for high minimum operating pressure differentials.

Common Questions

What are the symptoms of a failing solenoid coil in this valve?
Common signs include a buzzing or "chattering" sound, which often indicates low voltage or mechanical obstruction. If the valve fails to open when energized, the coil should be tested for continuity using a multimeter to check for an internal short or burnout.

Can this valve be used for outdoor applications?
The standard 8214250CSA-24V comes with a NEMA 1 enclosure, which is intended for indoor use. For outdoor or washdown environments, a version with a NEMA 3, 4, or 4X rating would typically be required to ensure environmental protection.

Why is my gas valve not closing completely?
Failure to close is often caused by debris or pipe scale trapped between the disc and the seat. Given the double-disc design, regular maintenance and the use of upstream gas strainers are recommended to prevent contaminants from compromising the redundant seal.
