Product information

The ball valves VL-421T and VL-422T from EPI are robust, 2-piece stainless steel ball valves for demanding industrial applications. They offer full bore, high pressure ratings (PN63 and PN100 respectively) and, thanks to the ISO 5211 mounting flange, are ideal for automation with pneumatic or electric actuators. With an anti-blowout stem and FDA/EC1935 conformity they meet the highest safety and hygiene standards.

Special features

  • 2-piece stainless steel body (1.4408)
  • Full bore – minimum pressure loss
  • Druckstufen: PN63 (VL-421T), PN100 (VL-422T)
  • Female thread to DIN 2999 / DIN EN 10226-1
  • Mounting flange to ISO 5211 – for direct automation
  • Anti-blowout stem – increased safety
  • Temperature range: -10 °C to +200 °C
  • FDA- and EG1935-konform, TA-Luft, PED
  • Antistatic version

Areas of application

  • Threaded lines from DN 15 to DN 80
  • Process lines up to 63 bar
  • Applications with a TA Luft requirement
  • Automated valves via ISO 5211

Advantages

  • Two-piece design in stainless steel, DN 15 to DN 80
  • Druckstufe PN 63
  • Female thread to DIN 2999 or DIN EN 10226-1
  • Mounting flange to ISO 5211, TA-Luft-Nachweis

Selection and installation

With PN 63 this series is well above the usual threaded ball valves – the temperature range extends from -10 to +200 °C. If you want to automate, use the standard ISO 5211 mounting flange.
