What is a Flanged Resilient Seated Gate Valve (NRS)?

A Flanged Resilient Seated Gate Valve (NRS) is a type of valve used for fluid control. It features a flanged connection for secure installation, a resilient rubber-coated gate for tight sealing, and a non-rising stem (NRS) design, meaning the stem does not move up or down while operating the valve. This design makes it ideal for underground and space-constrained applications.

Advantages of Flanged Resilient Seated Gate Valve (NRS)

• Superior Sealing Performance – The rubber-coated gate ensures a leak-proof seal, even at low pressure.

• Non-Rising Stem (NRS) Design – The stem remains in place, making it ideal for confined spaces and underground installations.

• Corrosion Resistance – Made from ductile iron with an epoxy coating, preventing rust and increasing durability.

• Easy Operation – Low torque design ensures smooth opening and closing, reducing manual effort.

• Low Maintenance Cost – Simple structure with wear-resistant sealing, minimizing maintenance needs.

• Bidirectional Flow – Allows fluid to flow in both directions, enhancing system flexibility.

• Anti-Deposition Design – Smooth inner chamber and rubber-coated gate prevent dirt buildup, making it suitable for clean and wastewater systems.

Applications in Waterworks

• Municipal Water Supply – Used in urban water distribution systems for reliable flow control.

• Wastewater Treatment – Applied in sewage treatment plants and drainage pipelines.

• Agricultural Irrigation – Ensures efficient water supply in irrigation networks.

• Industrial Water Systems – Used in cooling water and circulation systems in factories.

• Fire Protection Systems – Installed in fire hydrant networks and underground fire pipelines.

• Pump Stations – Controls water flow in pumping stations, preventing backflow.
