Valve-hints

Drinking water must always be free of germs, fit for consumption and pure. Consumers have great confidence in the quality of drinking water, particularly in Europe. Parts 1 and 2 of the European EN 1074 norm lay down the minimum requirements for gate...

When disk check valves are used, the minimum flow velocity is frequently not reached. This causes the valve to lose more pressure than in the case of a fully open position. As soon as the disk is not completely open, a relatively high amount of...

This is a question frequently asked by planning and field assembly companies.

The VAG EKN® Butterfly Valve uses nickel-chromium alloy (ratio 71:19). The property of chromium is that at high temperatures, it has a high affinity to bond with carbon.

Its special design allows its use in both water and waste-water applications. For maintenance and cleaning purposes, the disk of the valve can simply be turned out and the valve does not need to be dismantled from the pipeline.

The hollow-jet discharge valve consists of a cylindrical body pipe with a jet guiding cone on the outlet.

The VAG Technical Service offers its customers a global network of service technicians who competently solve any problem thanks to the expertise they have gained in many years of experience.

If necessary, a VAG HYsec Hydraulic Brake and Lift Unit can reliably open or close a valve (butterfly valve or plunger valve).

In order to ensure that the flow to control valves is as optimal as possible, thus achieving reliable pressure control, installation directly downstream of elbows and shut-off valves should be avoided.

The Kv value is the volume flow of a medium per time unit with a pressure drop of 1 bar at a specific temperature.
