A valve comprises a housing, a conduit, and a shut-off member, and a plurality of ribs. The conduit is fixed in position relative to the housing. The ribs are spaced from the conduit. The shut-off member is fixed in position within a cavity of the housing via the ribs. The gate has a fluid passageway extending therethrough and is movable relative to the shut-off member between opened and closed positions. The gate is able to linearly reciprocate between opened and closed positions along the center axis of the conduit. The gate is 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 allows fluid to flow through the fluid passageway of the gate.
