AWWA Metal Seat Gate Valve (NRS) 125/150LBS

Description

The AWWA Metal Seat Gate Valve (NRS) is engineered for rugged reliability in industrial sectors where metal-to-metal seating is required for extreme durability. Designed for heavy-duty isolation and flow control, this valve provides long-lasting performance in environments where resilient seals may not be suitable, such as high-temperature systems or applications with abrasive media.

Technical Specifications

• Design Standard: Conforms to AWWA requirements for metal-seated gate valves.

• Pressure Rating: 125 LBS / 150 LBS (Class 125/150).

• Body Material: High-strength Cast Iron or Ductile Iron.

• Seating: Precision-machined metal-to-metal seats for robust mechanical sealing.

• Stem Design: Non-Rising Stem (NRS) configuration, ideal for limited-space installations and underground municipal usage.

• Connection: Flanged ends per ASME B16.1 Class 125.

• Coating: Durable exterior epoxy coating for protection against environmental corrosion in Qatar’s coastal industrial zones.

Key Applications

• High-Temperature Industrial Lines: Suited for processes where standard rubber seals may degrade.

• Abrasive Media Handling: Metal seating offers increased resistance to wear in particulate-heavy flows.

• Power & Processing Plants: Reliable isolation for cooling and auxiliary fluid circuits.

• Large-Scale Infrastructure: Essential for long-term pipeline maintenance in Ras Laffan and Messaied industrial complexes.
