Kartar Dual Plate Check Valve (Non-Return Valve)
Overview
The Kartar Dual Plate Check Valve (NRV) is a robust, high-performance non-return valve engineered for reliable one-way flow control in water, fire-fighting, and industrial applications. Manufactured by Kartar Valves Pvt. Ltd. — a trusted Indian valve manufacturer with a reputation for quality and cost-effectiveness — this check valve is specifically designed for installation in pump discharge lines, fire protection systems, and water supply pipelines to prevent backflow and protect equipment from damage.
Also known as a Non-Return Valve (NRV) , the dual plate check valve operates automatically, opening with forward flow and closing rapidly under reverse flow to prevent water hammer and system damage. Its wafer-type, slimline construction allows for easy installation between standard flanges, while the dual spring-loaded plates ensure tight shut-off even at low differential pressures .
Whether you’re equipping a municipal water supply system, a fire hydrant network, a pumping station, or an industrial process line, the Kartar Dual Plate Check Valve delivers the reliability, durability, and performance you need for efficient flow control.
Key Features
