A segmented fluid end assembly has a first module having a body with a first side surface and a slot formed therein and extending along at least a portion of the first side surface, a second module having a body with a first side surface and having a slot formed in the first side surface and generally aligned with the slot of the first module, and a connector received in the slots of the first and second module so as to fix the first module against the second module. The connector is in the nature of a wedge. Each of the slots has a generally dovetail configuration. The wedge has a generally hourglass cross-section. The wedge is engaged in friction-fit relationship in the slots.

A system including a pneumatic actuator having an actuator element, the system further including a compressed-air provision device which is configured to carry out a closed-loop position control of the actuator element by applying compressed air to the pneumatic actuator. The compressed-air provision device is further configured to carry out an assistance procedure in which the actuator element is set in an oscillation movement, pressure values and position values are detected, and, on the basis of the detected pressure values and the detected position values, friction information and/or mass information is determined and/or verified.

A manifold for connecting two or more fluid control devices to a common fluid source. The manifold includes a first manifold block adapted to be coupled to a first fluid control device, and a second manifold block adapted to be coupled to a second fluid control device. The manifold also includes a first slot formed in the first manifold block and a second slot formed in the second manifold block. The first slot and second slot each have a substantially circular shape in cross-section. The manifold further includes a slot connector configured to couple the first manifold block and the second manifold block together, the slot connector having a first end sized to be disposed in the first slot and a second end sized to be disposed in the second slot.

A control device has a plurality of modular control sections (12a-12d), which form a control block when arranged beside one another and have units of an electromagnetically actuatable actuator system and/or of a sensor system for controlling or monitoring a valve apparatus, which are connected to a central energy supply and/or monitoring device, which have individual connection parts (20a-20d) assigned to the particular control section (12a-12d), and which are connected in series and to one another. At least some of the connection parts (20a-20d) used are wirelessly in direct engagement with one another by way of their plug parts (22a-22c) and socket parts (24a-24c) that face one another and are adjacent to one another.

A solenoid valve assembly has a valve body in which a spool is slidably mounted and operated by a solenoid having a coil. A manifold member has a plurality of flow paths for supplying and discharging pressurized fluid to and from ports of the solenoid valve assembly. An intermediate block is interposed between the valve body and the manifold member. The intermediate block has a plurality of through holes for connecting ports of the manifold member to ports on the valve body. At least one sensor is housed in the intermediate block for sensing at least one of pressure and flow in at least one of the through holes.

A hydraulic valve includes an on/off seat-type main valve with two ports having a displaceable poppet for opening and closing the main flow channel; an on/off seat-type pilot valve with three ports, with a magnetomotive force producing coil, a magnetic circuit, and an anchor movable with the magnetomotive force produced by the coil; and a frame with required channels and spaces for the poppet and for the anchor. Closing the inlet channel displaces the poppet and opens the main flow channel. Opening the inlet channel forces the poppet to close the main channel. The anchor includes a frame with a first sealing element for closing the low-pressure outlet channel of the pilot valve and with a second sealing element for securing the closing of the high-pressure inlet channel of the pilot valve. The sealing surface of the second sealing element is movable in relation to the frame of the anchor.

The present disclosure relates to the field of fluid process systems and discloses a manifold system for fluid delivery. The system comprises a first set of Solenoid Operated Valves (SOVs), a second set of SOVs, a plurality of isolating valves, at least one first shuttle valve, and at least one redundant shuttle valve. Each set of SOVs includes at least two SOVs arranged in parallel. The SOVs together form a series-parallel redundancy. Each isolating valve is coupled to an SOV and facilitates hot swapping of that SOV. The redundant shuttle valves provide redundancy to the first shuttle valve and facilitate the flow of a fluid from each of the first set of SOVs to each of the second set of SOVs, thereby promoting system safety and availability.

The present invention relates to a fluid control device and a connector for the same. The connector includes a first unit and a second unit to form a connector in a particular shape. Thus, the connector and an adjacent connector can be stacked upon each other to allow simple disassembling. The present invention also provides a fluid control device including the connector.

An expandable solenoid system having a sequence controller assembly and at least two zone expander solenoid valve assemblies fastened in a staggered configuration. Each zone expander solenoid valve assembly has a zone expander solenoid and a flanged valve body assembly. The valve block has threaded bolt holes, unthreaded bolt holes, an output port, and a threaded pressure source port having an O-ring groove. The threaded bolt holes and the unthreaded bolt holes have different depths and are alternately positioned around a perimeter of the valve block. The first flanged valve body assembly is fastened to the second flanged valve body assembly and so on, in a staggered configuration, whereby respective zone expander solenoids are in a zigzag geometry and creating an expandable manifold.

A zoned fluid control system in a valve manifold system has a plurality of manifold blocks connected together and a plurality of control valves mounted to the manifold blocks with the control valves being electrically actuated and pilot pressure operated. The plurality of manifold blocks forms at least first and second separate pilot pressure passages of a respective first zone and second zone not connected to each other for supplying a respective first set and second set of control valves with independently controlled pilot pressure. A pilot supply valve selectively supplies pilot pressure and shuts off pilot pressure to the second pilot pressure passage without affecting the pilot pressure to the first pilot pressure passage thereby disabling the second set of control valves as a separate zone independent from the first set of control valves.
