Features:
  1. High Durability and Abrasion Resistance: Metal seats are exceptionally resistant to erosion, wear, and tear caused by abrasive fluids or particles flowing through the valve.
  2. Superior Leak Resistance: Metal-to-metal contact between the ball and seats provides a tighter seal, minimizing leakage compared to soft-seated valves.
  3. High-Temperature Performance: Metal components can withstand higher operating temperatures than valves with soft seats.
  4. Extended Service Life: The robust construction and wear-resistant seats contribute to a longer lifespan.
  5. Bidirectional Flow: Some models allow flow in either direction, offering flexibility in piping layouts.

Benefits:

  1. Ideal for harsh environments: Well-suited for applications with abrasive fluids, slurries, or high temperatures.
  2. Reduced maintenance needs: Durable metal seats minimize wear and tear, leading to less frequent maintenance compared to soft-seated valves.
  3. Minimized fugitive emissions: Superior leak resistance helps reduce environmental impact.
  4. Reliable shutoff performance: Metal-to-metal sealing ensures a secure closure.
  5. Versatility: Available in various sizes and materials for diverse industrial applications.

FAQs:

    • Superior durability and abrasion resistance: Metal seats can withstand harsh environments with abrasive fluids or particles.
    • Tighter sealing and reduced leakage: Metal-to-metal contact provides a more reliable seal.
    • Higher temperature capabilities: Metal components can handle higher operating temperatures.
    • Higher initial cost: The use of metal seats and robust construction can make them more expensive than soft-seated valves.
    • Potentially higher torque requirements: Metal-to-metal contact may require slightly more torque to operate the valve compared to soft seats.
    • Not ideal for clean fluids: Metal seats may not be necessary for applications with clean, non-abrasive fluids.
    • Soft-seated floating ball valves: A more cost-effective option for clean fluids and less demanding applications.
    • Trunnion mounted ball valves: Offer better support for the ball at high pressures, but may not be necessary for all applications with metal seats.
