The Kartar Dual Plate NRV is a high-performance non-return valve engineered for fire protection systems and industrial piping networks. Designed in the dual-plate (double-door) wafer-type configuration, it features two spring-loaded plates that hinge toward the center this ensures rapid closure upon flow reversal, minimizing water hammer and pressure loss while offering a more compact, lightweight alternative to conventional swing check valves. Built in full compliance with IS:5312 standard and ISI marked, the valve is available across a wide size range from 50 mm to 300 mm (or larger) and supports pressure ratings such as PN 10 or PN 16, depending on the specific model.

The body is typically crafted from cast iron (or ductile iron), with discs made from durable malleable iron or stainless steel, and stainless-steel torsion springs to facilitate reliable, non-slam operation. Its wafer-style form factor simplifies installation between flanged pipe spools, saving space and reducing support needs. Performance-wise, the dual-plate design opens fully during forward flow, offering minimal pressure drop, and the plates close before any backflow begins, effectively preventing reverse flow and protecting pumps or hydrant lines. This makes the Kartar Dual Plate NRV ideal for firefighting systems, booster pump discharge lines, municipal water mains, and other applications where one-way fluid control with minimal hydraulic impact is critical.
