UNI-D UW-15 Normally Closed 2/2 Way Solenoid Valve
The UNI-D UW-15 Normally Closed 2/2 Way Solenoid Valve is a high-quality, precision-engineered valve designed by Pro UNI-D Co., Ltd. for reliable fluid control in industrial and commercial applications. Featuring a direct-acting, multiplex diaphragm design, this normally closed (NC) solenoid valve ensures dependable performance for managing the flow of water, air, light oil, gas, and vacuum, making it an essential component for automation systems, irrigation, and process control.
Key Features
Direct-Acting Design: Operates effectively under low or zero pressure, providing reliable performance without requiring a minimum pressure differential.
Normally Closed (NC) Operation: The valve remains closed when de-energized and opens when the coil is powered, ideal for applications where safety and energy efficiency are priorities.
Versatile Fluid Compatibility: Suitable for water, air, light oil (viscosity ≤20 cSt), gas, and vacuum, with customizable seal options including Viton (130°C), Silicone (130°C), or EPDM (130°C, available for UW-20~25).
Durable Construction: Crafted with a brass valve body and NBR oil seal for corrosion resistance and longevity in demanding environments.
Compact and Easy to Install: Features a 1/2" pipe size with BSP, NPT, or BSPT threaded connections for seamless integration into piping systems.
Electrical Specifications: Supports AC110V/220V (50/60Hz) or DC24V, with voltage tolerances of ±10% (AC) and ±1% (DC) for stable operation.
Why Choose the UNI-D UW-15 Solenoid Valve?
The UNI-D UW-15 is designed for professionals seeking a robust and versatile solenoid valve for fluid control. Its direct-acting mechanism ensures reliable operation even in low-pressure conditions, while the brass construction and high-quality seals provide durability and resistance to wear. The valve’s compact design and horizontal installation requirement make it easy to incorporate into various systems, from water treatment to pneumatic automation. With a maximum fluid temperature of 80°C and a pressure range of 0-10 bar (AC) or 0-7 bar (DC), this valve delivers consistent performance across a wide range of applications.
For added longevity, a Y-line filter is recommended to prevent contaminants from affecting valve performance. The valve’s high CV factor (4.5) and 15mm orifice ensure efficient flow rates, making it suitable for both small and medium-scale systems.
