What is a DVGW Valve?

That is a EC Type examined valve to DVGW (German GAS installation and plumbing association) requirements.

Where are they used?

Firing systems, gas turbines and other oil and gas appliances are operated with DVGW safety valves that shut off the fuel supply should dangerous conditions arise.  

What is required?

Type examination is mandatory to establish their suitability for this purpose. For the gases specified by DVGW Code of Practice G 260, the requirements of EN 161 and DIN 3394 Part 1 must be met for working pressures in excess of 4 bar. Liquid fuels are governed by the requirements of EN 264.

The old DIN DVGW registration number has been superseded in the course of EU harmonization. DVGW valves are not gas appliances ready for use as defined in the Gas Appliance Directive. The valves are marked with the CE product identification number rather than the CE mark.

Our program

Norgren has developed 2 series of electrically and electro pneumatically actuated valves of the brand Buschjost. The 82580 series is only suitable for gaseous fuels, the series 82090 for gaseous and liquid fuels.

These valves are described in greater detail on their data sheets. Find out more here.
