    • Valve housing with high pressure inlet from line and high pressure outlet to load. Housing has coaxial bores with poppet or spool valve in small bore to control high pressure flow. Valve connected by stem to piston in large bore and valve is normally urged to closed position with fluid leakage through piston exiting through bleed hole. Closure for bleed hole operated by low pressure piston or diaphragm (1 psi or less) to build up pressure on free end of piston and move it to open valve.
    • 阀体采用高压入口从高压出口到负载。 外壳具有同轴孔,带有小孔中的提升阀或滑阀,以控制高压流量。 通过阀杆连接到大孔和阀门中的活塞通常被推动到关闭位置,通过活塞通过泄放孔流出液体泄漏。 关闭泄放孔,由低压活塞或隔膜(1 psi或更小)操作,以在活塞自由端上形成压力并将其移动到打开阀门。

    • Apparatus for supporting and connecting fluid control and/or conditioning units such as air filters, lubricators and pressure regulators to permit flow of fluid through such units in series. The apparatus is of a kind employing supporting frames in which the units can be inserted to bring inlet and outlet ports of the units into sealed registration with peripheral openings in the frames. To enable frames to be connected in series into a fluid line without the need to interpose a linking conduit, insert components are provided for insertion through peripheral openings of the different frames. When the frames are assembled in series these insert components co-operate to provide a fluid path from a unit in one frame to a unit in the next frame.
    • 用于支撑和连接流体控制和/或调节单元(例如空气过滤器,润滑器和压力调节器)以允许流体通过这些单元串联流动的装置。 该设备是一种采用支撑框架的装置,其中可以插入单元以使单元的入口和出口与框架中的周边开口密封对准。 为了使框架能够串联连接成流体管线,而不需要插入连接管道,提供插入部件用于插入通过不同框架的周边开口。 当框架串联组装时,这些插入部件协作以提供从一个框架中的单元到下一个框架中的单元的流体路径。
