Precision Operation: The 1/2" NPT port size ensures that this normally closed valve responds swiftly, opening and closing in less than 1 second. This precise operation, alongside a lifecycle of over a million cycles, provides reliability and efficiency for critical fluid control applications. Optimized for High-Temperature Applications: This valve is specifically designed for high-temperature use and is suitable with gasoline, diesel fuel, kerosene oil, natural gas, air, and similar fluids. It is not intended for use with drinking water or in water-related projects. Duty Cycle Guidance: While built for strong performance, this 12V DC solenoid valve is not designed for continuous operation exceeding 8 hours per cycle. For continuous duty requirements, motorized ball valves are recommended. Extended Service Life: Designed for long-term performance with a tested lifespan of over one million cycles. The seal delivers excellent chemical resistance and is rated for high-temperature environments. Durable Construction: Constructed from industrial-grade brass, this electric solenoid valve offers durability and consistent performance under demanding conditions.
