The new venting valves from GF Piping Systems are now even more reliable; every detail has been exceptionally well thought out.

An innovative PP-H (PVDF) float on the air and venting valve type 591 has a very low density of 0.91 g/cm³ and ensures complete and reliable venting of the pipe system. At the same time, the valve prevents media overflow. The venting valve type 595 is used wherever safe and controlled air inlet is a must, for example when emptying tanks.
