The innovative design features independent spring action for each plate, reducing spring twist by half compared to conventional designs. This significantly prolongs the lifespan of the springs.

With a wide range of impressive features and more, R&D Multiple’s Dual Plate Check Valves offer the best combination of features, workmanship, and cost-effectiveness, making them the optimal choice for various applications in terms of Features, Workmanship, Initial and running costs.

Swing type Non-Return Valves (NRVs) have been widely used over the years, and their simplicity remains their greatest advantage. R&D Multiple’s Swing Check Valve is characterized by robustness and leak-tightness. The incorporation of a slant disc and an eccentrically loaded door ensures shorter door travel and enables quick reflux closing action, preventing door slamming and its undesirable effects. You can rely on these NRVs with confidence and enjoy peace of mind.
