  • Abrasive –  materials, coatings and hardening processes, as well as designs to reduce velocities and cavitation
  • High Temperature – metal seats, and Class VI shut-off to 1200 ºF/649 ºC
  • Corrosive –materials such as Hastelloy, Inconel, Titanium, Alloy 20 and more
  • High Cycle – 1,000,000 cycle packing guarantee i
  • Cryogenic –we offer the Dual Pak with a full cryogenic extension to cover -270 ºC/-436 ºF
Gosco F Class Soft or Metal Seated Valves

F-Class Metal Seated Ball Valves – Fast, Flexible Flawless Metal-Seated Ball Valves

Features & Benefits:

  • Lockable T-handle, gearbox and actuated options
  • Oversized shaft to prevent twisting
  • Horseshoe body plates are made from less expensive WC6 (F11) material. Since they are not wetted components, they do not have to be the same material as the body, bonnet and flanges
  • Optional dual packing sets eliminate shaft leaks
  • Blow-out proof shaft design ensures safety
  • Pressures up to Class 600
  • ANSI/DIN/RTJ flanged, butt weld, NPT, BSPT, and socket weld end connections
  • Ball and seats have the most advanced coating/surface hardening technology options available, to provide the best solution for critical applications
  • Metal ball and seats are lap matched to provide tight shut-off
  • Only four components (body, bonnet and flanges) need to be manufactured on demand for any valve, regardless of size, pressure class or
    material. Available in all commercially available materials (Hastelloy, Alloy 20, Duplex, etc.)
  • Fully bi-directional live loaded seats compensate for thermal and pressure variances, ensuring the best possible seal, even at low pressures
  • Arcuate cut ball for abrasive or high velocity applications. Optional Vari-V ball for precise flow control applications
  • Patented scalloped ring to prevent build-up of material between the seat and the spring

F-Class Valves Include:
