Tecval VB-20 3-Pieces Ball Valve is a Forged Body design. The forging process reduces the surface porosity and closes up internal cavities. The result is mechanical stronger and more durable product, especially suitable for working in high corrosive environment. They are manufactured under ASME B16.34.

Features

  • Unique design Forged Body and Flanges.
  • Full bore (FB) or Standard bore (SB).
  • Compensation springs on packing stem.
  • Three pieces to allow a full disassembling.
  • Easy cleaning and maintenance.
  • No ejectable stem design.
  • 316 SS handle to reduce the risk of corrosion.
  • 100% tested.

Options

  • Flanged ends.
  • PEEK seats for high pressures 200bar (2900PSI).
  • Prepared for a quick automation (ISO 5211).
  • Male-Female (MxF) end connections.
  • Male-Male (MxM) end connections.
  • Degreased for oxygen service.
  • Handle safety lockout.
  • Antistatic device.
  • O-ring seals available in several materials.
