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.

An electromagnetic valve manifold includes valve assemblies arranged in a single direction, each valve assembly including electromagnetic valves arranged in the single direction, a slave station disposed at one of ends of the electromagnetic valve manifold in the single direction, and a valve driving unit disposed in correspondence with each of the valve assemblies. The slave station includes a slave station output port that sends a control signal and valve driving unit power to the valve driving units. The valve driving units each include an electromagnetic valve power input port that receives electromagnetic valve power from an external device and a circuit board configured to control driving of the electromagnetic valves of a corresponding one of the valve assemblies using the control signal and send the electromagnetic valve power to the electromagnetic valves.

A valve block body for arranging on a drive mount includes multiple process fluid ducts, between which valve seats are arranged. Multiple drive connection sections are assigned to the valve seats, which are arranged on at least one side of the valve block body. Multiple clamping sections are arranged facing away from at least one side of the valve block body.

A fluid control system for supplying fluid to a fluid consumer, having a valve module including a channel body to which a fluid switching valve, a fluid pressure regulator and a vacuum switching valve are attached, the channel body having a first fluid channel extending from a fluid input port to an input port of the fluid pressure regulator and having a second fluid channel extending from an output port of the fluid pressure regulator to an input port of the fluid switching valve, and having a third fluid channel extending from an output port of the fluid switching valve to a fluid consumer port, and having a first vacuum channel extending from a vacuum input port to an input port of the vacuum switching valve, and having a second vacuum channel extending from an output port of the vacuum switching valve to the fluid consumer port.

A pneumatic system for a medical fluid machine operating a medical fluid cassette, the pneumatic system including an interface for supplying positive pneumatic pressure and negative pneumatic pressure to the medical fluid cassette; a source of positive pneumatic pressure; a source of negative pneumatic pressure; and a pneumatic pump including a first head and a second head, wherein the first head is dedicated to supplying positive pneumatic pressure to the positive pneumatic pressure source and the second head is dedicated to supplying negative pneumatic pressure to the negative pneumatic pressure source.

A Hydraulic Manifold Control Assembly for use in connection with surface blowout preventers and diverter control systems. Said Hydraulic Manifold Control Assembly incorporates design elements and methods which reduce overall envelope dimensions, improving maintenance accessibility, thereby reducing overall installation and manufacturing time and ultimately contributing to a more robust, cost effective end-product. Said design elements and methods include: the use of intrinsically safe I/O modules and components; the employment of a removable valve assembly rack installation method; the use of a removable face plate for identification of flow control valves; the implementation of a digital automatic diverter sequence; the use of integrated manifold assemblies; and the integration of a wide-range function count.

A protruding section formed at the one side end of a connector section provided in a valve is inserted into a recessed section formed as part of a valve placement section of a fluid apparatus. The valve is caused to pivot with the inserted portion that serves as a supporting point, and an engaging section formed at the front end of a lever of a hook section formed at the other side end of the connector section is allowed to engage with an engaging protruding section formed as part of the valve placement section of the fluid apparatus. The valve is thus attached to the fluid apparatus.

A fluid control device comprises includes: a joint block defining a fluid flow path open to an upper surface thereof, and which has an engaging portion on the bottom surface side thereof; a support member having a guide portion which restrains the joint block on the upper surface while permitting the joint block to move in longitudinal direction; and a fluid device fixed to the upper surface of the joint block. The support member is provided with at least one plunger such that the tip end portion protrudes from the upper surface of the support member. A recess is provided in the bottom surface of the joint block, and the recess engages with the tip end portion of the plunger to set the position of the joint block in the longitudinal direction.

A fluid control device includes; upstream side and downstream side joint blocks defining a fluid flow path, and having engaging portions at a bottom surface side; a support member having a guide portion to which the engaging portions of the upstream side and downstream side joint blocks can be engaged; and a fluid device supported by the support member via the upstream side and the downstream side joint blocks; wherein the upstream side and the downstream side joint blocks are fixed to the guide portion by utilizing a reaction force against a bending force generated by the tightening force of fastening bolts to the upstream side and the downstream side joint blocks and the fluid device connected together, and the length of the engaging portions in the longitudinal direction of the joint blocks is formed shorter than the length of the joint blocks.
