Patent ID: 7708024

Claim:
A method comprising: partially assembling a valve, the valve comprising a housing, a conduit, and a shut-off member, and a plurality of ribs, the housing having a cavity, the conduit having a fluid passageway extending therethrough and being fixed in position relative to the housing, the fluid passageway of the conduit having a center axis, the ribs being spaced from the conduit and circumferentially spaced from each other about the center axis, each of the ribs having an innermost edge nearest the center axis, the innermost edge of each of the ribs diverging away from the center axis as such rib extends a first direction along the center axis, the shut-off member being fixed in position within the cavity of the housing via the ribs, the gate having a fluid passageway extending therethrough and being movable relative to the shut-off member between opened and closed positions, at least a portion of the conduit being slidably received within the fluid passageway of the gate, the gate be able to linearly reciprocate between opened and closed positions along the center axis, the fluid passageway of the conduit being in fluid communication with the fluid passageway of the gate when the gate is in the opened position and when the gate is in the closed position, the gate being engaged with the shut-off member when the gate is in the closed position in a manner preventing fluid from flowing through the fluid passageway of the gate, the opened position of the gate allowing fluid to flow through the fluid passageway of the gate; and driving a wedge member between the innermost edges of the ribs in a second direction, the second direction being opposite the first direction, the driving of the wedge member radially compressing the ribs against the housing.
