VAG Quality
Patented and certified - approved valves

Gate valves and butterfly valves, non-return valves, plunger valves, hollow-jet discharge valves, air valves, control valves, house connection valves and fire hydrants - VAG valves can be found in virtually all water works, power plants and pumping stations as well as in numerous building connection systems. There’s a good reason for that: Numerous successful patent applications and certificates for our company and its products are proof of our know-how and expertise in innovative valve development. However, quality checking comes before the awards.
VAG is a founding member of the Quality Association for Heavy Corrosion Protection of Valves and Fittings by Powder Coating (GSK), an association for companies that manufacture valves and fittings with epoxy powder coatings in accordance with the requirements of the RAL-GZ 662 quality assurance standard.
VAG uses coating materials approved for use in drinking water, and our production facilities are monitored twice a year by independent, accredited testing institutes.
VAG is known for the excellent quality and durability of its products. Below, we would like to give you a brief overview of the coating tests we conduct:
Whether high water pressure or extreme temperatures, the material must be the right one. In extensive coating tests as well as pressure, leak-tightness and functional tests we simulate the emergencies that your systems must cope with every day. In addition to mathematical calculations, we carry out specific model trials in our own VAG test field. If necessary, we make use of the capacities of renowned universities.
