NRS Gate Valve

Our NRS gate valve features an aluminum bronze bearing embedded in the gate leaf, offering excellent self-lubrication and high-strength impact resistance. The bearing can be replaced without replacing the entire gate after long-term use wear. The full EPDM vulcanized wedge piece ensures complete shut-off and can absorb small particles in the flow. Maintenance-free and corrosion-resistant multi-stem O-rings ensure higher durability.You can make the purchase through FUXEON®. We have the goods in stock.

Technical parameters

Our advantages

The resilient seat NRS gate valve is a single package bonded product, integrating the valve body, resilient seat and gate via advanced bonding technology. Its resilient seat achieves excellent sealing through elastic deformation when closed, solving common issues of poor sealing, leakage and rust in ordinary valves. The integrated design also reduces overall volume, effectively saving installation space and simplifying on-site maintenance.

The non-rising stem gate valve uses GGG40/50 ductile iron for its body and discs, which offers high impact and tensile resistance after strict heat treatment. It is widely used as a regulating and shut-off device for fluid pipelines in water, sewage, petroleum, chemical, food, pharmaceutical, power, shipbuilding, metallurgy and energy systems, suitable for various media and providing stable service.

The ductile iron NRS gate valve features a full-bore design, where the valve channel inner diameter matches the connected pipeline. This minimizes pressure loss and flow resistance, improving fluid transport efficiency and energy savings, especially for large-flow systems. Its smooth inner wall also reduces residue accumulation, lowering blockage risks and extending service life.

The flanged NRS gate valve adopts a fixed wedge structure to prevent gate vibration, avoiding seat wear and ensuring long-term sealing. Its precision-machined valve stem enables low-torque operation, facilitating manual or automatic control and reducing wear. The flanged connection allows easy installation and disassembly, suitable for large-diameter pipelines and maintenance-intensive occasions.

FAQ

Q1: What is an NRS gate valve?

A1: NRS refers to Non-Rising Stem gate valve. The stem will not extend outward when opening or closing, saving installation space, widely used in water supply, fire protection and pipeline engineering.

Q2: What are the main application scenarios of NRS gate valve?

A2: It is suitable for limited space such as buried pipelines, valve wells, underground pipe galleries and narrow equipment rooms, commonly used in municipal waterworks, fire fighting systems and industrial water pipelines.

Q3: Is the NRS gate valve easy for daily inspection and maintenance?

A3: Yes. It is equipped with a visual opening and closing indicator, which can quickly judge the valve state. The overall structure is compact, sealed reliably, and needs less daily maintenance with long service life.
