Quabbin, Inc. Manufactures Low-leak Rotovalves for VAG, USA

48" Rotovalves leak tested far below industry standard

Because of Quabbin, Inc.’s experience with the Rotovalve line, VAG, USA contracted with Quabbin, Inc. to manufacture two 48” Rotovalves with leak requirements so low that several manufacturers refused even to bid the job. The valve specs stated no more than 7.2 oz/min, with the normal industry standard for a valve this size being 19.2 oz/min. The Quality Engineer for the customer, East Park Reservoir in Philadelphia, PA, witnessed the leak testing. Not only did the valves meet the required specs, they exceeded them. The two sides of the first valve both passed at 2 oz/min, and the two sides of the second valve at 3 and 5 oz/min: one-tenth and one-fourth, respectively, of the normal industry standard!
