AWWA Metal Seat Gate Valve (R.S.) 125/150LBS

Description

The AWWA Metal Seat Gate Valve (R.S.) is engineered for critical industrial applications where the Rising Stem (R.S.) design is essential for immediate visual verification of the valve position. Featuring precision-machined metal-to-metal seating, this valve is designed to excel in high-temperature environments, abrasive media, and systems where resilient (rubber-based) seats may not be the optimal choice.

Technical Specifications

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

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

• Stem Type: Rising Stem (R.S.) — stem rises as the valve opens for clear visual status.

• Seating: Precision-machined metal-to-metal contact for maximum durability.

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

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

• Corrosion Protection: Exterior epoxy coating suitable for Qatar’s humid industrial environments.

Key Applications

• High-Temperature Infrastructure: Suitable for systems where fluid temperatures exceed the limits of standard rubber seals.

• Abrasive Media: Metal seating provides increased longevity in lines carrying particulates or solids.

• Critical Isolation: R.S. design allows maintenance and operations teams to see at a glance if the line is isolated.

• Industrial Complexes: Essential flow control for Ras Laffan, Messaied, and other major industrial hubs in Qatar.
