Gas non-return valves / Check valves 
Safety devices in accordance with EN ISO 5175-2

Type: GRV 20, GRV 25, GRV 32, GRV 50

Highlights

• Gas non-return valve for very low cracking pressures of 4 – 6 mbar
• High flow rates, minimal pressure loss
• Position-independent installation
• Prevents dangerous gas mixtures on the inlet side
• Stainless steel dust filter with large filter surface ensures a long service life
• Registered under the DVGW certification mark NG-4390CQ0062

Application areas of the products are thermal process plants in the area of public gas supply as well as heating processes for welding, cutting, and related processes that are operated with mixtures of fuel gas and air. In this area the safety devices are used to safeguard plants, pipeline systems and tapping points and prevent gas return.

The gas non-return valves (check valves) are available in three sizes, DN 20, DN 25, DN 32 and DN 50 with thread from 1/2" to 2" as well as special thread, in brass or stainless steel.
