  • Method of installing rotatable flapper valve to an interior of a conduit
    Patent number: 8381401
    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.

  • Snap action valve with bumper pad
    Patent number: 8191572
    Abstract: A rotary valve plate adapted for housing within a conduit employs a vibration absorbing bumper pad coupled to the valve plate at a surface thereof adapted to contact an inner surface of the conduit whenever the valve plate is rotated to a closed position. The bumper pad minimizes vibratory noise and improves the durability of the valve plate over extended periods of operation.
