Double the Protection, Zero Compromise
In modern municipal and residential plumbing, the prevention of back-siphonage is not just a technical preference—it is a critical safety requirement. Veyron Valve’s Dual Check Valve series is engineered to provide a redundant fail-safe against back-pressure and back-flow. By placing two independent, spring-loaded check modules in series, we ensure that even if one seal is compromised by mineral deposits or debris, the second remains active to protect the integrity of the primary water source.
Precision Engineering: The Science of Spring Tension
The core performance of a dual check valve is defined by its "cracking pressure" and the responsiveness of its internal components.
- Independent Modular Design: Each of the two internal check modules operates autonomously. This design ensures that the valve remains effective even under fluctuating pressure conditions where a single-seat valve might flutter or fail to seal completely.
- Low Head Loss Flow Path: We have optimized the internal geometry to minimize turbulence. The streamlined flow-way ensures that despite having two barriers, the pressure drop (Delta P) remains remarkably low, maintaining efficient delivery to the downstream system.
- Stainless Steel Torsion: Our springs are manufactured from high-grade Stainless Steel 302/316, providing the precise tension required for instantaneous closure. This rapid response is the first line of defense against the "back-siphonage" effect caused by sudden drops in city main pressure.

Installation & Maintenance Flexibility
Field contractors prefer Veyron Valve’s dual check series because of its service-in-place capability. The internal check modules are designed as self-contained cartridges. Should the valve require maintenance due to extreme water hardness, the cartridges can be swapped in minutes without the need for specialized tools or removing the valve body from the piping network.
Furthermore, the compact, space-saving envelope allows for installation in tight meter boxes or indoor utility rooms. Whether configured with NPT, BSP, or solder ends, the valve provides a robust solution for water heaters, residential service lines, and carbonators.
Why Veyron Valve?
Every dual check valve we produce undergoes a dual-stage pressure test. We verify the low-pressure sealing capability (drip-tight) and high-pressure structural integrity before the product leaves our facility. For B2B distributors and utility providers, this means fewer call-backs and absolute confidence in the safety of the local water supply.
