ASCO 821453CSA Solenoid Valve

The ASCO 8214G53CSA (also identified as 821453CSA) is a high-performance 2-way normally open solenoid valve designed specifically for fuel gas vent valve applications. Built with a lightweight and durable aluminum body and high-quality NBR seals, this valve ensures reliable operation in critical gas train systems. Featuring a 1-inch NPT pipe size and a high flow capacity of 21 Cv, it is rated for a heating capacity of up to 1,179,000 BTU/hr. Operating on 120Vac, this ASCO gas solenoid valve is engineered for low-pressure systems, maintaining precise control within a 0-5 PSI range. The NEMA 1 enclosure provides essential protection for indoor industrial settings. Whether you are performing a commercial boiler repair or upgrading a gas train assembly, this valve delivers the technical precision required for modern HVACR gas safety systems and fuel management protocols.

Common Questions

How does a normally open solenoid valve function in a gas vent system?
In a fuel gas vent application, a normally open valve remains open when de-energized, allowing gas to vent safely. When power is applied, the ASCO 8214G53CSA closes to seal the system.

What is the maximum pressure rating for the ASCO 821453CSA?
This specific model is designed for low-pressure gas systems, with a functional operating pressure range of 0 to 5 PSI.

Can this valve be used for liquids or high-temperature steam?
No, the 821453CSA is specifically engineered as a fuel gas solenoid valve for dry gas media and is not intended for liquid or high-temperature steam service.
