DVGW & EN 331 Gas-Approved Ball Valves – Certified Safety for Gas Control Systems

Looking for DVGW and EN 331 approved gas ball valves for your pipeline project, LPG system, or industrial gas control application? Safety is non-negotiable when it comes to natural gas, LPG, methane, or biogas lines—and using a valve that meets international gas safety standards like EN 331 and DVGW (Germany) is the smart, regulatory-compliant way to ensure leak-free and explosion-proof operation.

At Perfect Engineers, we offer certified gas ball valves built to withstand high-pressure gas service while ensuring operational reliability, flame resistance, and full shut-off sealing.

What Are EN 331 & DVGW Certifications?

  • EN 331: European standard for manually operated ball valves used in gas installations—including appliances, domestic pipelines, and industrial gas distribution.
  • DVGW: German certification body (Deutscher Verein des Gas- und Wasserfaches) that tests and certifies gas and water safety components for compliance with EU safety standards.

Both standards verify that the valve:

  • Has leak-proof shut-off at full pressure
  • Is fire-safe, anti-static, and corrosion-resistant
  • Operates reliably under sudden temperature and pressure changes

Key Features of DVGW / EN 331 Gas Valves

  1. Working pressure: Up to 5 bar (domestic) / 16 bar (industrial)
  2. Temperature range: -20°C to +60°C (extended versions available)
  3. Yellow aluminum or steel handle (as per gas valve color code)
  4. Body Material: Brass CW617N, SS316, or Carbon Steel
  5. Full bore or reduced bore options
  6. Blow-out proof stem
  7. Anti-static and fire-safe design (where applicable)
  8. ISO 7/1 threaded ends (BSP / NPT), flanged, or compression type

Applications of Gas-Approved Ball Valves

Industry / Use Case Application Point
Residential Gas Systems LPG / NG supply to appliances, meters
Commercial Kitchens Shut-off valves for burners, ovens
Industrial Gas Piping Main shut-off, pressure regulation
Gas Skid Packages Isolation, safety shut-off
LPG Bottling & Distribution Loading/unloading control lines
Biogas & Methane Plants Digestor pipelines, flare lines
