Product description
Emerson ASCO's L182D-BIG-NPT solenoid valves are engineered for high-performance fluid control in demanding industrial environments. These 2/2 Normally Closed diaphragm pilot operated valves are available in port sizes of 1 1/4", 1 1/2", and G 2" NPT, offering installation flexibility across a wide range of systems. Their full orifice design ensures maximum flow capacity, minimising pressure drop and enhancing overall system efficiency. Ideal for applications involving both liquid and gaseous media, these valves are commonly used in water treatment, HVAC, and general industrial automation where safe and reliable shutoff is essential.
The L182D-BIG-NPT series supports an operating pressure differential of up to 10 bar, making them suitable for medium-pressure systems where stability and control are critical. Built with durability in mind, these valves feature an IP67-rated enclosure, providing excellent protection against dust and temporary water immersion—ideal for outdoor or washdown environments. In addition to their robust construction and performance, the valves are designed for easy maintenance, helping reduce downtime and increase system uptime. With a combination of flow efficiency, reliability, and environmental resistance, the L182D-BIG-NPT valves deliver long-term value in a variety of industrial fluid control applications.
