R&D Multiple’s Dual Plate Check Valves offer unparalleled features and exceptional craftsmanship, making them the ideal choice for various waterworks applications. The inclusion of a clamped resilient seat on the valve body ensures a high level of seal integrity and provides assurance against seal wash-off.

The innovative design incorporates independent spring action for each plate, resulting in a significant reduction in spring twist compared to conventional designs. This greatly extends the lifespan of the springs, enhancing the overall durability of the valves.

When considering the multitude of features and more, R&D Multiple’s Dual Plate Check Valves outperform the competition in terms of features, workmanship, initial costs, and long-term operating costs. They represent the optimal choice in every aspect.

Swing type Non-Return Valves (NRVs) have been widely employed over the years, thanks to their simplicity as the key advantage. R&D Multiple’s Swing Check Valve excels in robustness and leak-tightness. The incorporation of a slant disc and an eccentrically loaded door enables shorter door travel and ensures a swift reflux closing action, preventing door slamming and its associated undesirable effects. You can rely on these NRVs with confidence, allowing you to relax and enjoy peace of mind.
