Metal Seated Ball Valves: The Ultimate Solution for Extreme Temperatures and Pressures
In processes involving abrasive slurries, high-pressure steam, or temperatures exceeding 250°C to 400°C, standard PTFE or polymer seats will degrade. FlowBiz Metal Seated Ball Valves are designed to bridge this gap, offering a robust metal-to-metal interface that ensures a reliable seal under the harshest industrial conditions.
Advanced Surface Hardening Technologies
At FlowBiz, we utilize cutting-edge hardening techniques to ensure the ball and seat can withstand mechanical wear and thermal shock. Depending on your specific application, we offer:
- Electroless Nickel Plating (ENP): Provides excellent corrosion resistance and moderate hardness for mid-range temperatures.
- Stellite Hard-Facing (PTA Welding): Using Plasma Thermal Arc welding to apply Cobalt-based alloys for superior wear resistance.
- HVOF (High-Velocity Oxygen Fuel): A premium spray technique that applies Tungsten Carbide or Chromium Carbide over a cobalt base. This is the gold standard for high-velocity abrasive applications.
- Nitriding: Used on austenitic stainless steel (SS304/SS316) to create a super-hard surface layer without compromising the core's toughness.
- Chromium Plating: Offers a smooth, hard finish to reduce torque and prevent galling.

Key Advantages of the FlowBiz Design
- Zero Soft-Part Failure: By eliminating elastomeric seats, we prevent the risk of "seat blowout" or melting in high-heat zones.
- Abrasion Resistance: Perfectly suited for media containing solid particles, catalysts, or coal ash that would tear soft seats.
- Low Maintenance: The hard-coated surfaces reduce the frequency of seat replacements, significantly lowering the total cost of ownership.
- Positive Shut-off: Each ball and seat set is precision-lapped as a matching pair to ensure a bubble-tight seal.
