Kartar Cast Iron Reflux Non-Return Valves are designed to automatically prevent reverse flow in pipelines, protecting pumps, motors, and other equipment from backflow damage. The swing-type disc opens with forward flow and closes automatically when the flow reverses, ensuring reliable non-return operation. These valves are widely used in water supply, irrigation, fire protection, pumping stations, and industrial utility systems. They are manufactured in accordance with IS 5312 standards and are available with metal or rubber seating. Design & Construction: Body Material: Cast Iron (IS 210 FG 200) Cover: Bolted Cast Iron Cover Disc Type: Swing Type Renewable Disc Seat: Gunmetal/Bronze Seat Ring or Rubber Seat (model dependent) Hinge Pin: Stainless Steel Operation: Automatic Swing Check Mechanism End Connection: Flanged Ends as per IS 1538 Standards & Specifications: Design Standard: IS 5312 (Part 1) Pressure Rating: PN10 / PN16 Testing Standard: Hydraulic Shell & Seat Test as per IS 5312 Available Sizes: DN50 (2“) to DN300 (12“) and larger on request Working Medium: Water, Air, Oil and other compatible non-corrosive fluids. Features: Automatic prevention of reverse flow Heavy-duty cast iron construction Low pressure loss with swing disc design Renewable disc and seat for longer service life Corrosion-resistant internal components Leak-tight sealing performance Easy installation and low maintenance Long operational life Applications: Water Supply & Distribution Systems Pumping Stations Fire Fighting Systems Irrigation Networks Water Treatment Plants Industrial Utility Pipelines Municipal Water Projects HVAC & Cooling Water Systems Advantages: Protects pumps and pipelines from backflow Reduces maintenance and operating costs Durable and reliable construction Suitable for horizontal and vertical installations (upward flow in vertical pipelines) Manufactured in accordance with Indian Standards for dependable industrial and municipal applications.

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.

Kartar Double Orifice Kinetic Air Valves are designed to automatically release large volumes of trapped air during pipeline filling and continuously release small air pockets during operation. They also admit air rapidly during pipeline draining, preventing vacuum formation and protecting pipelines from collapse and water hammer. These valves are ideal for water supply, irrigation, sewage, fire protection, and industrial utility pipelines. They are manufactured in accordance with IS 14845 standards and are available in tamper-proof designs. Design & Construction: Body Material: Cast Iron (CI) / Ductile Iron (DI) Cover: Cast Iron / Ductile Iron Float Material: Stainless Steel (SS304) or Rubber-Coated Float (model dependent) Internal Components: Stainless Steel / Bronze Seat Material: Nitrile Rubber (NBR) / EPDM Operation: Automatic Float Operated End Connection: Flanged Ends Standards & Specifications: Design Standard: IS 14845 Pressure Rating: PN10 / PN16 Available Sizes: DN40 (40 mm) to DN150 (150 mm) End Flange: IS / BS Standard Drilling Testing: Hydraulic Shell & Seat Test as per IS 14845 Features: Double orifice design for efficient air release Automatically releases large and small volumes of air Admits air during pipeline emptying to prevent vacuum Reduces water hammer and surge effects Tamper-proof construction available Corrosion-resistant epoxy-coated body Low maintenance with long service life Smooth and reliable float mechanism Applications: Water Supply & Distribution Networks Irrigation Projects Pumping Stations Water Treatment Plants Sewage & Wastewater Systems Fire Fighting Networks Industrial Utility Pipelines Municipal Infrastructure Projects Advantages: Prevents air locking and vacuum formation Improves pipeline efficiency and pump performance Protects pipelines from water hammer Durable construction with corrosion-resistant coating Reliable automatic operation with minimal maintenance Manufactured under ISO 9001-certified quality systems and compliant with IS 14845 requirements.
