摘要： A fluid flow control valve that may be used as both a check valve and a relief valve. The valve includes a moveable valve member having a surface capable of forming two or more valve seal areas with two or more valve seat surfaces on a valve seat member. The valve seat surfaces may be formed by coining a portion of valve seat surfaces on fingers of the valve seat member. One of the valve seat fingers in inclined from the outlet toward the inlet. The valve seat member is metal, forming a metal to metal valve seat arrangement with the valve seat member.

摘要： The regulator connects to a high pressure fluid supply and regulates the pressure to a downstream apparatus. If an over-pressure occurs, it is vented to atmosphere. A segmented body reduces production costs. An elongate control stem engages a supply seal assembly and a vent seal assembly and moves axially with respect to these seal assemblies to achieve regulation and venting. Both the supply seal assembly and the vent seal assembly are bi-directional and operate when forces are applied from opposing directions.

摘要： The normally closed, two-position, three-way latching hydroseal valve can be used in subsea applications in connection with the production of oil and natural gas. The latching hydroseal valve can be operated by remote pilot valves to open and close the latching hydroseal valve or in an alternative embodiment attached solenoid pilot valves can be used. The seal carrier has pistons of different diameters to latch the valve open after the pilot fluid is vented to atmosphere. The main seal assembly includes a bi-directional seal.

摘要： A chatter resistant shuttle valve is provided to direct fluid flow from at least two sources of pressurized fluid to a downstream apparatus. The shuttle valve includes a valve body with a shuttle valve member movably mounted inside. A dampening chamber is provided which dampen opening movement of the shuttle as it moved from a closed position on one side of the shuttle toward a closed position on the other end of the shuttle. One or more dampening chambers may be provided.

摘要： One of the low voltage output windings of a standard ballast circuit is coupled to one filament of a pair of series connected fluorescent lamps by an external current controller. The current controller acts to restrictively reduce the operating voltage applied to the filaments of one of the lamps to which it is connected, below firing value during start up operation and thereafter maintain a lower running voltage for the lamps without adversely affecting restart.

摘要： The precision regulator connects to a high pressure fluid source and regulates the pressure to a downstream apparatus. If an overpressure occurs, it can be vented to atmosphere. An elongate control stem engages a supply seal assembly and a vent seal assembly and moves axially and past these seal assemblies to achieve regulation and venting. The set point of the regulator can be adjusted by rotation of an adjustment knob that adjusts the position of the elongate control stem relative to the supply seal assembly and the vent seal assembly. Regulation is achieved primarily by use of a sensor piston which transfers fluid pressure from a regulated port to the sensor piston which is opposed by a spring. Both the supply seal assembly and the vent seal assembly rely upon an o-ring and a seal ring to achieve a seal with the outside circumference of the control stem. The o-ring is compressed and distorted, thus exerting forces against the seal ring to achieve a better seal. Both the supply seal assembly and the vent seal assembly are bi-directional and operate when forces are applied to the o-ring in different directions.

摘要： The pressure biased shuttle valve assembly in the pressure biased shuttle valve operates in conjunction with a remote operated vehicle (ROV) to actuate blow-out preventers and thus shut in the well during emergency situations. The pressure biased shuttle valve assembly opens in response to fluid pressure from the ROV. It requires little or no flow to open. These pressure biased shuttle valves are typically located subsea on a lower marine riser platform (LMRP). These platforms are sometimes brought to the surface for a periodic testing and maintenance. The pressure biased shuttle valve assembly is also used as a repair kit which facilitates easy maintenance and repair when the LMRP is brought to the surface. In one embodiment, the shuttle is rigidly connected to a piston rod. In another embodiment, there is a flexible connection between the piston rod and shuttle. The purpose of the flexible connection is to encourage a better seal in smaller size valves.
摘要翻译： 压力往复阀中的压力偏压梭阀组件与远程操作的车辆（ROV）一起操作以致动防喷器，从而在紧急情况下关闭井。 压力偏压梭阀组件响应于来自ROV的流体压力而打开。 它需要很少或没有流动打开。 这些压力偏压梭阀通常位于下海洋立管平台（LMRP）的海底。 这些平台有时被带到表面进行定期测试和维护。 压力偏心梭阀组件也用作修理套件，当LMRP被带到表面时便于维护和修理。 在一个实施例中，梭子刚性地连接到活塞杆。 在另一个实施例中，在活塞杆和梭之间存在柔性连接。 柔性连接的目的是为了鼓励更小尺寸的阀门更好的密封。
