The cylindrical plug of the resin valve turns easily on a film of sealant, providing a leak-free seal. This design permits maximum port openings through the plug, including full pipe area, a distinct advantage over tapered plugs. And, since tapered plug valves often lock up and require re-lubrication each time the valve is to be cycled, the resin valve requires only an occasional charge of sealant to operate efficiently.
