Abstract
A ball valve comprising a seat having a first opening thereon, a housing over the seat having a second opening defined by a flap having an inner and outer diameter, and a ball in the housing, the ball having a diameter great than the inner diameter of the flap. The seat may be formed directly onto a metal insert of a bonded piston seal, or directly onto a wall of any chamber needing a ball valve therein. The housing may be formed as an extension of a piece of rubber used to seal the periphery of the insert or chamber wall. Hence, the housing and insert or chamber wall may be molded together as part of a unitarily formed chamber and ball valve combination.
