The RSO Series 2-way 2-position miniature solenoid valve is an electromagnetically driven control valve specifically engineered for high-precision fluid pipeline control and space-constrained automation equipment. Featuring an extremely compact profile, this series covers a size spectrum from DN6 to DN8 and fully supports high-precision NPT thread connections, greatly facilitating rapid embedded installation within precision instruments, medical devices, and small-scale piping networks. Utilizing a direct-acting drive structure, the valve achieves zero differential pressure startup and operates stably across the entire 0 to 20 bar pressure range, delivering exceptional responsiveness and rapid open/close cycling. Available in high-quality forged Brass or corrosion-resistant engineering Plastic, the valve bodies are universally compatible with water, general liquids, and gases, making them ideal components for small-flow automated fluid control systems.

Feature
Miniature Footprint & Precision Threads: Custom-tailored for small-bore DN6 and DN8 pipelines with an ultra-compact geometry to optimize layout space. The standard NPT thread connections secure a seamless match with domestic and international high-precision piping layouts.
Zero Differential Pressure Direct Response: Powered by a precision direct-acting mechanism, the valve requires no minimum operating pressure differential and executes instantaneous opening or closing strokes smoothly within a wide pressure span of 0 to 20 bar.
Material Diversity for Varied Workloads: Forged Brass variants offer outstanding mechanical strength for general water and air loops, while engineering Plastic models are lightweight and provide enhanced corrosion resistance, successfully broadening medium compatibility.
All-Weather Freeze Resilience: With an operational temperature range from -20 to 65 ℃, the elastomeric seals and valve body resist hardening and cracking in freezing outdoor winter environments, guaranteeing long-term leak-proof gas-tight integrity.
