Abstract
A method of assembly of a rotatable flapper valve to an interior of a conduit features the ability to couple the valve plate to its axle outside of the conduit in an independent operation. The conduit is split into first and second sections each having a flared end and a pair of indentations for receipt of the valve axle. While separated, the valve axle is placed in a pair of indentations in one of the conduit sections and then the second conduit section is moved into abutting engagement such that its indentations also partially surround the axle. The first and second conduit sections are then joined by welding.
