Color-plated Copper-made First-stage Pressure-reducing Valve

This first-stage pressure-reducing valve is engineered from high-quality, plated copper to provide dependable and precise regulation of high-pressure air (up to 3000 PSI) for scuba diving. The robust copper construction ensures superior corrosion resistance, significantly extending the valve's service life in demanding saltwater environments. With a consistent intermediate pressure output (typically around 140 PSI above ambient), it delivers smooth, stable airflow to your second-stage regulator, enabling effortless breathing and reducing fatigue during dives.

Rigorously tested for performance under real-world conditions, this valve features a balanced diaphragm design that minimizes pressure variations with depth, ensuring reliable operation whether you're at 10 meters or 40 meters. Its precision-machined internal components are built to withstand frequent use, offering a service life that often exceeds 500 dives with proper maintenance. The efficient flow characteristics help conserve air, allowing for longer bottom times.
