A BVA is an Excellent Pig used for batching, cleaning with maneuverability of tight 90’s and as a chasing pig. BVA’s & Filming Pigs were designed to fit ball valves. Used most commonly as the lead pig in filming applications. BVA’s can be built with a bolt in the back end for attaching Wire Wheel Brushes.
Filming pigs were designed to apply (inhibit) any type of coating or film on the interior of pipe walls. In order to apply a film, the pig is designed with a by-pass disc and a spreading disc, which is machined as per line specification. The unique conenose has greater maneuverability around short bends, such as 45°’s, 90°’s and T’s. Filming pigs, like all solid cast urethane products, can be manufactured in the variety of durometers available for flexibility or more chemical resistant. When you order filming pigs with extra discs (3 or more) we alternate the notching on those discs for even bypass of the inhibitor.
