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 needs. Optimized for High-Temperature Applications: This valve is specifically engineered for high-temperature environments and is suitable for use with gasoline, diesel fuel, kerosene oil, natural gas, air, and similar fluids. Note: It should not be used with drinking water or in water-related applications. Duty Cycle Consideration: While designed for robust performance, this 12V DC solenoid valve is not intended for continuous operation beyond 8 hours in a single cycle. For applications requiring continuous duty, motorized ball valves are recommended. Extended Life Span: Built for longevity with a life cycle exceeding one million cycles, ensuring dependable service when properly maintained. The seal offers excellent chemical resistance and is designed to withstand high temperatures. Durable Construction: This electric solenoid valve is constructed from industrial-grade brass, providing durability and reliable performance.
