GH-4003 Brass water meter check valve

The brass water meter check valve is a critical safeguard in water distribution systems, constructed from brass to ensure corrosion resistance and compliance with standards for potable water safety. Designed to prevent backflow and maintain metering accuracy, it utilizes a swing check or spring-assisted mechanism that automatically seals against reverse flow caused by pressure fluctuations, protecting pipelines from contamination. Its optimized internal geometry minimizes pressure loss while preserving hydraulic efficiency, and the durable brass body withstands temperatures from -20°C to 110°C and pressures up to 16 Bar, making it suitable for residential, commercial, and municipal water systems. Featuring standardized NPT threads for seamless integration, the valve’s compact design allows easy installation directly after water meters in both vertical and horizontal orientations. The stainless steel spring or nitrile rubber seal ensures reliable, maintenance-free performance in applications ranging from irrigation and fire protection to treated wastewater systems. With tamper-resistant construction and resistance to chlorine and scale buildup, this valve combines long-term durability with adherence to ISO 228/EN 10226 specifications, delivering a cost-effective solution for ensuring water quality, system integrity, and uninterrupted supply across diverse environments.
