Proven valve quality has a name: VAG. Every valve that leaves our company does so only after passing through an intensive testing process. Each newly developed product is tested for possible stress, forces acting on it, cavitation risks and constructional conditions by computer analyses and flow simulations. The factors to be tested are defined by the subsequent areas of application, i.e. your specifications. We only release your valve for dispatch when all pressure, leak-tightness and function tests have been perfectly completed.
