TECVAL

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 Reduced bore (RB).
  • 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

  • PEEK seats for high pressures 210bar (3000PSI).
  • Prepared for a quick automation (ISO 5211).
  • Male-Female (MxF) end connections.
  • Male-Male (MxM) end connections.
  • VIC Grooved end connections.
  • Flanged connections.
  • Handle safety lockout.
  • Antistatic device.
