At Cair Valve, we manufacture high-quality CI (Cast Iron) and DI (Ductile Iron) Double Flanged Metal Seated Gate Valves for demanding industrial and water infrastructure applications. Our valves use a metal-to-metal seating design, providing reliable shut-off, long service life, and dependable performance in applications where high pressure, abrasive media, or elevated temperatures make resilient seated valves less suitable.

Unlike rubber-seated valves, a metal seated gate valve seals through precision-machined metallic contact between the wedge and the seat. This design offers excellent durability while allowing the valve to operate reliably in challenging environments.

Why Choose a Metal Seated Gate Valve?

When your application involves harsh operating conditions, a metal seated gate valve delivers dependable performance with minimal maintenance. It is ideal for pipelines where the valve is mainly used in the fully open or fully closed position to isolate flow.

Body Design

• Straight-through full bore design for smooth, bi-directional flow.
• Strong CI or DI body with double flanged ends for secure installation.
• Internal guide ribs accurately align the stem and wedge during operation.
• Precision-machined seating surfaces provide consistent sealing and long service life.
• Suitable for both manual handwheel operation and electric actuator automation.

Key Features & Benefits

• Heavy-duty metal-to-metal seating for extended durability.
• Performs reliably under high pressure and elevated temperatures.
• Resistant to wear caused by abrasive particles and suspended solids.
• Low pressure loss due to full bore flow path.
• Corrosion-resistant construction for long operating life.
• Available with manual or motorized electric actuator operation.
• Designed for water supply, wastewater, hydropower, irrigation, industrial plants, and process pipelines.

Manual or Motorized – Which Is Better?

The right choice depends on your application.

Manual Metal Seated Gate Valve

• Cost-effective for standard installations.
• Simple operation with minimal maintenance.
• Ideal where valves are operated occasionally.

Motorized Metal Seated Gate Valve

• Remote operation without manual intervention.
• Suitable for automation and SCADA systems.
• Controlled opening and closing for improved system management.
• Reduces operator effort and improves safety in difficult locations.

Before Selecting a Valve

Choosing the correct valve begins with understanding your process. Our engineering team first discusses your application and then recommends the most suitable solution.

Please share:

• What fluid or medium will flow through the pipeline?
• Is the valve required only for isolation, or is controlled operation also needed?
• What are the operating pressure and temperature?
• Do you prefer manual or electric actuator operation?
• What valve size and flange standard are required?

After understanding your requirements, we recommend the best metal seated or resilient seated gate valve for reliable long-term performance.
