20110147634 | Ball Valve - A ball valve, in particular for highly pressurized media, with a valve housing ( | 06-23-2011 |
20120298902 | ELECTRIC FLOATING BALL VALVE - The present invention discloses an electric floating ball valve. The electric floating ball valve addresses the problems of the existing electric floating ball valve, such as poor reliability, high tendency to be damaged, poor control precision, high noises in operation as well as high costs for maintenance and replacement. The electric floating ball valve includes a valve body, a valve stem, a valve core and a drive mechanism. The drive mechanism is connected with the outer end of the valve stem and could drive the said valve stem to rotate. The external side of the valve stem is covered with a cylindrical heat sink made of metallic materials. Said heat sink is fixedly connected with said valve body. The heat sink of the electric floating valve could significantly improve the heat radiation capacity, which efficiently guarantees the stable and reliable operation of the drive mechanism. | 11-29-2012 |
20130037738 | BALL VALVE - A ball valve which can suppress the increasing of processing labor time and reliably prevent simultaneous rotation of a ball seat and a ball when the ball is rotated by handle manipulation is provided. The valve body | 02-14-2013 |

251315040 | Ceramic (e.g., glass or fired clay) | 1 |
20090108224 | VALVE - A valve comprises a housing and at least three ceramic discs in the housing such that at least two fixed ceramic discs are provided and at least one rotatable ceramic disc is provided between the fixed ceramic discs. The ceramic discs comprise through holes such that when the holes are aligned, the valve is open, and turning the rotatable ceramic disc turns the holes to be misaligned in successive ceramic discs, which prevents water flow through the valve. The valve further comprises a handle for rotating a rotatable ceramic disc and the handle comprises a stem extending through the housing, and a curved part, the curved part curving at least partly around the housing along the circumference of the housing. | 04-30-2009 |

20110017931 | BALL VALVE - The present invention provides a ball valve, comprising a valve base, a ball element, a valve shaft and a locking element. The valve base has a containing space opening inside for containing the ball element, and having a lining layer on its inner wall. The locking element is threaded onto one side of the valve base, and correspondingly having a lining layer on its inner wall to separate water and metal materials (mainly refers to lead), in order to prevent contamination from metal material to water. | 01-27-2011 |
20110260090 | BALL VALVE WITH SINGLE ACCESS PORT - A ball valve with single access port includes a ball valve body; a ball disposed inside the ball valve body, the ball having an open inside portion creating a primary passage, an operating position of the ball determining the flow of fluid and pressurized cleaning agent through the valve; a secondary passage configured to allow the flow of the pressurized cleaning agent into the open inside portion of the ball and an access port allowing an external source of the pressurized cleaning agent to be coupled to the ball valve. | 10-27-2011 |
20120080631 | BOTTOM ENTRY PLASTIC BALL VALVE - A bottom entry plastic ball valve comprises a valve stem cap ( | 04-05-2012 |
20120080632 | TOP ENTRY PLASTIC BALL VALVE - A top entry plastic ball valve comprises a valve stem cap ( | 04-05-2012 |
20120273709 | Plastic Ball Valve Assembly - A plastic ball valve assembly, includes a valve body part including a valve body made of plastic material and having a flow channel passing, a ball member having a through passage therein and rotatably located in the flow channel and a handle member, and a connecting part detachably connecting with the valve body part, including a pair of connecting caps engaged with the two ends of the valve body respectively, a pair of connecting heads made of different materials, each having a head made in different shapes. The multi-use ball is easy to be installed, reliable to be sealed, and strong in practicability. | 11-01-2012 |
