Description

Kartar Dual Plate NRVs are compact, spring-assisted wafer-type non-return valves designed to automatically prevent reverse flow in pipelines. The dual spring-loaded plates open with forward flow and close rapidly when the flow stops, minimizing water hammer and protecting pumps, compressors, and piping systems. These valves are ideal for water supply, fire protection, HVAC, irrigation, and industrial process applications. Design & Construction: Body Material: Cast Iron (CI) / Ductile Iron (DI) Disc Material: Stainless Steel (SS304 / SS316) or SG Iron (model dependent) Spring Material: Stainless Steel Seat Material: EPDM / NBR (application dependent) Hinge Pin: Stainless Steel Type: Wafer Type, Dual Plate, Spring Assisted End Connection: Wafer Type (Suitable for PN10 / PN16 Flanges) Standards & Specifications: Design Standard: API 594 / IS 5312 (applicable models) Testing Standard: API 598 Pressure Rating: PN10 / PN16 Available Sizes: DN50 (50 mm) to DN600 (600 mm) Installation: Horizontal or Vertical (upward flow) depending on service conditions. Features: Compact wafer design with reduced face-to-face dimensions Dual spring-loaded plates for quick closing Prevents reverse flow and minimizes water hammer Low pressure drop Corrosion-resistant construction Lightweight and easy to install Low maintenance and long service life Suitable for high-flow industrial applications Applications: Water Supply & Distribution Systems Fire Fighting Systems HVAC Installations Pump Discharge Lines Irrigation Networks Water & Wastewater Treatment Plants Industrial Utility Pipelines Chemical & Process Industries Advantages: Fast-closing mechanism protects pumps and pipelines Compact and lightweight compared to swing check valves Reliable leak-tight performance Easy installation between flanges Long service life with minimal maintenance Manufactured in a wide range of sizes for commercial and industrial applications.
