Air Operated Shutoff Valves for Hydrogen - TESCOM™ VA/VG Series

  • The TESCOM VA/VG series valve offering is a go-to solution for on/off hydrogen flow control at high pressure with over 20 years of field experience.
  • Learning together with our customers, we have developed unique features that enable significant cost savings for station manufacturers and operators alike.

Key features

  • SAFETY: The VA/VG series is equipped with a leak capture feature that ensures any hydrogen getting past the seals over time is captured and ported away safely instead of escaping to the atmosphere.
  • RELIABILITY: The VA/VG series features a balanced valve design which offers longer cycle life than alternative valve configurations such as ball or needle valves.
  • SAVINGS: The flexible 360° port orientation of the VA/VG series allows hydrogen station and dispenser manufacturers to reduce the cost of their system by removing the need to bend pipes, use extra T-fittings, and take up extra space to accommodate larger less robust shutoff valve solutions.
  • EASY MAINTENACE: Servicing VA/VG series valves is easy and quick – simply remove the bonnet, install the replacement cartridge, and tighten the bonnet back onto the body.
