- Product Details
1. First in the Market – Direct 220V Plug-in Design
The World’s First Household Gas Solenoid Valve That Connects Directly to 220V AC Without a Transformer.
Unlike traditional valves that require a voltage converter or low-voltage input,
the SR-512(1/2‘’)is designed to be directly connected to standard household 220V power supply,
simplifying installation and improving energy efficiency.
2. Industrial-Grade Reliability – Zero Gas Leakage
Engineered with Industrial Standards for Ultimate Safety – Zero Leakage Guaranteed.
While most household gas valves may have minor seepage over time, the SR-512(1/2‘’) adopts an industrial-level sealing mechanism,
ensuring NO gas leakage, making it the safest choice for your customers' homes.
3. Unique & Intelligent Design – Dual Steel Ball Sealing Mechanism
How Do We Achieve “Zero Leakage”? – Patented Steel Ball Sealing Technology.
The secret lies in its ingenious internal structure, which utilizes two precisely positioned small steel balls that seal
the gas passage perfectly when the valve is closed.
This mechanical design ensures a fail-safe, tight seal, far surpassing
traditional rubber or diaphragm-based valves in reliability and leak prevention.
4. High-End Product – No Domestic Sales, Premium Pricing Available
Exclusive B2B Model – Not Available for Domestic Retail.
The SR-512(1/2‘’) is a sample-level / B2B-only product, not sold in the domestic retail market, allowing you to position it as a premium,
exclusive solution for importers, wholesalers, and safety-focused OEMs. High pricing power & great margin potential.
“Certifications in process / Compliant with international safety standards”
