The UNi-D (2L)UW-50 Solenoid Valve is a brass, 2-way, normally closed (NC) valve that uses an electrical signal to control the flow of various fluids, including water, air, and light oil. It's a semi-direct diaphragm-operated valve, meaning it can operate even with zero differential pressure, and it features a large 2-inch pipe size for high-flow applications. This robust valve is commonly found in industrial pipeline systems for dispensing, gas shutoff, or tank draining, and offers reliable performance across a wide range of temperatures and pressures. Features of the UNi-D (2L)UW-50 Solenoid Valve for steam use: 2-Way, Normally Closed (NC): Stops fluid flow when de-energized and allows flow when energized. Semi-Direct Diaphragm Operated: Can operate from zero differential pressure, making it versatile for various system conditions. High Flow Capacity: Features a large 2-inch pipe size and orifice, suitable for applications requiring significant fluid throughput. Durable Construction: Valve body is typically made from forged brass, with internal components like the tube and core often made of stainless steel, ensuring longevity. Versatile Fluid Compatibility: Designed to handle a range of media including water, air, and light oil. Standard Seal Options: Commonly uses NBR (Buna) seals for a media temperature range of − 5 ∘ C to 8 0 ∘ C . Viton (FKM) seals are often available as an option for higher temperatures (up to 12 0 ∘ C ). Wide Voltage Range: Available in various standard voltages, including 220 VAC , 110 VAC , 24 VDC , etc. Easy Installation: Designed for ease of installation, typically requiring vertical upright mounting. Certifications: Often holds certifications like ISO9001 and CE. Specifications of the UNi-D (2L)UW-50 Solenoid Valve: Model Series: UW Series Valve Type: 2-Way, 2-Position, Normally Closed (NC) Operation: Semi-Direct Diaphragm Operated, Zero Differential Pressure Start Pipe Size: 2 inch (UW-50, equivalent to G2" or NPT 2") Orifice Size: 50 mm
