Latest Patents

One of Takeda's latest patents involves a ball valve and methods of fabrication. This invention features a ball valve where a ball seat, made of synthetic resin, is mounted at each end of a flow passage within the ball. The sealing end portion of the ball seat contacts the spherical surface of the ball only when the ball is in the closed position. In the open position, the lip of the ball seat falls within a recess surrounding the end of the flow passage. A gap of 0.3 to 0.7 mm is created in the open position between the wall surface of the recess and the end of the lip. Additionally, the end of the lip is designed to fall about 0.2 mm inside an imaginary continuation of the surface of the ball at the recess when the ball is open.
