ABSTRACT:
A valve structure is provided having a housing with an open top valve chamber and inlet and outlet passages on opposite sides of the valve chamber forming a through passage with the valve chamber through said housing, a generally spherical radius valve seat on each passage at the valve chamber, a bonnet removably covering said valve chamber, a stem extending through said bonnet generally axially of the valve chamber, a pair of generally spherical radius closure discs in the valve chamber sealingly adapted to engage the valve seats, a disc carrier for each disc in the valve chamber, each disc carrier having a through passage in a plane transverse to the plane of the disc providing full flow therethrough from the inlet to the outlet passage when the valve is in opening position, an eccentric means provided on the stem and engaging each disc carrier for selectively moving the discs into and out of engagement with the valve seats and a guide between the bonnet and at least one of said disc carriers guiding the disc carriers on rotation of the stem from an open position in which the through passages in the disc carrier provides free flow between the inlet and outlet passages and a closed position in which the discs are aligned with the valve seats and holds the disc carriers in that position while the eccentric moves the discs selectively axially into and out of engagement with the valve seats.
