摘要： A fluid dispense system for use with a drum having a drum insert configured to couple with a bung included on a drum, the drum insert having an upper portion and a drum insert down tube extending therefrom into an interior of the drum. The system further having a dispense head configured to couple with the drum insert, the dispense head having first and second conduits, each having a valve assembly, the valve assemblies in operable communication with the drum insert when the dispense head is coupled with the drum insert. When the dispense head is coupled with the drum insert the first and second valve assemblies are effected to an open position enabling fluid to flow through the conduits. When the dispense head is not coupled with the drum insert the first and second valve assemblies are biased to a closed position inhibiting fluid from flowing through the conduits.

摘要： The invention disclosed is a weir valve with an adjustable bypass incorporated into the weir portion of the valve housing. The valve housing has an interior chamber with an inlet portion, a middle portion and outlet portion. An elongate weir traverses the middle portion of the interior chamber and separates the inlet portion and outlet portion. The top surface of the weir defines a valve seat. A diaphragm traverses the interior chamber and is moveable by a compressor onto the weir effecting a closure of the valve. The adjustable bypass consists of a bypass chamber which extends longitudinally of the elongate weir with inlet and outlet openings centrally located on the sides of the weir between the bypass chamber and the inlet portion and outlet portion respectively. A bypass valve member is adjustably moveable in the bypass chamber to variably restrict the communication between the inlet and outlet openings.

摘要： A position indicating valve for controlling the flow of fluids includes a flow housing with a valve seat and a valve poppet. A control housing is provided adjoining the flow housing with a centrally located, nonrotating valve stem having inward and outward ends. The stem is connected to the valve poppet at its inward end and is threaded at its outward end with an intermediate portion being threaded oppositely. An operating handle is rotatably mounted to the control housing with a configured central aperture therethrough into which the threaded outward end of the stem extends. A configured position indicator and stop is threadably mounted on the outward end of the stem within the aperture and is adapted to actually move inwardly and outwardly of the handle as the handle is rotated. A rotatable coupling is located partially within the control housing and is interlockable with the handle and threadably mounted to and about the stem at the threaded intermediate portion. The coupling is adapted to axially move the stem, the valve poppet and the indictor in the same direction with rotation of the operating handle. The indicator has a greater magnitude of movement than the poppet.

摘要： A valve has a contractible valve element formed of an inner laminae of PFA, an outer laminae of PTFE with the outer laminae having a boss to provide positive compression and positive distension of the valve element. The portion that constrict is welded to a PFA tubular end portion thus providing the advantages of a PTFE laminae with a boss and the PFA what it surfaces. The valve utilizes a valve mechanism which has a yoke which moves radially towards and away from the contractible valve element with linkages extending from yoke arms which connect to opposite sides of the contractible valve element. The valve element may thus be positively closed and positively opened. The hermetic seal between the outer PTFE laminae and the inner PFA laminae causes the inner laminae to extend outwardly when the outer laminae is positively distended thereby allowing the valve function where the fluid being controlled is under a negative pressure. The invention also includes the method of manufacturing the multiple layered valve element.
摘要翻译： 阀具有由PFA的内层形成的收缩阀元件，PTFE的外层，外层具有凸台，以提供阀元件的正压缩和正膨胀。 收缩的部分焊接到PFA管状端部，从而提供具有凸台的PTFE薄板和PFA表面的优点。 该阀利用阀机构，该阀机构具有从可收缩的阀元件径向移动并远离可收缩阀元件的轭，该连杆从连接到可收缩阀元件的相对侧的轭臂延伸。 因此，阀元件可以被正向闭合并且被正面打开。 外部PTFE薄片和内部PFA层之间的气密密封件使得当外层被正向膨胀时内层向外延伸，从而允许控制流体处于负压下的阀功能。 本发明还包括制造多层阀元件的方法。

摘要： A free draining, corrosive resistent valve for regulating the flow of corrosive fluids therethrough includes a plastic valve housing. An inlet passage extends into the housing and upwardly therein terminating in a valve seat. An inclined panel surrounds the inlet passage below the valve seat. An outlet passage extends from the lower most portion of the inclined panel through the housing. A plastic valve poppet is located above the seat having a diaphragm therearound with an upwardly extending stem. A plastic retainer is located above the diaphragm into which the stem extends. The retainer is adapted for affixing the diaphragm is a sealing relationship to the valve housing.

The portion that constrict is welded to a PFA tubular end portion thus providing the advantages of a PTFE laminae with a boss and the PFA what it surfaces. The valve utilizes a valve mechanism which has a yoke which moves radially towards and away from the contractible valve element with linkages extending from yoke arms which connect to opposite sides of the contractible valve element. The valve element may thus be positively closed and positively opened. The hermetic seal between the outer PTFE laminae and the inner PFA laminae causes the inner laminae to extend outwardly when the outer laminae is positively distended thereby allowing the valve function where the fluid being controlled is under a negative pressure. The invention also includes the method of manufacturing the multiple layered valve element.
