Dual Plate Check Valve (wafer type NRV) prevents reverse flow with a compact, low-pressure-drop design. Ideal for water, steam, air, oil, and process lines across industrial utilities and plants.
We manufacture & Exports Dual Plate Check Valves engineered for reliable non-return operation in pipelines. The dual spring-loaded plates enable quick closure, minimizing water hammer and backflow. Wafer design ensures easy installation between flanges with reduced face-to-face length and cost-effective performance.
Key Benefits
Prevents reverse flow; fast closure reduces water hammer
Compact wafer design; easy fit between flanges
Low pressure drop and stable sealing
Available in multiple MOC, sizes, and pressure classes
Suitable for horizontal/vertical (upward flow) installations
