A valve assembly has a basic module and a plurality of valve modules which are mounted on the basic module side by side along a line-up direction, the basic module having a lower portion, an upper portion and a connecting portion connecting the lower and the upper portion, which enclose a receiving space for at least one valve module on three sides. The basic module has a bottom surface facing outwards and an upper side facing outwards. At least one external fluid connection is provided which is arranged on the bottom surface or on the upper side. Furthermore, at least one external electrical connection is provided which is arranged on the bottom surface or on the upper side.

An electronic execution unit controls and regulates a pneumatic valve assembly for a pneumatic movement. An application for controlling and regulating a valve assembly is or can be loaded so that it can be carried out on the electronic execution unit to carry out the pneumatic movement on the pneumatic valve assembly. An electronic valve controller for the open-loop control and closed-loop control of a valve assembly has at least one pneumatic valve for a pneumatic movement task.

Techniques involve a hydraulic valve module having at least one hydraulic valve with a valve slide which can be adjusted by way of an electric actuator in order to supply hydraulic lines with hydraulic liquid by way of the hydraulic valve. The hydraulic valve module has a controller and an electric energy store. The controller and the electric energy store are set up to move the valve slide out of every possible valve slide position into a deactivation position by way of the electric actuator and energy which is stored in the electric energy store. This allows the safe operation of hydraulic valves without a restoring spring, wherein valves of this type and the actuators thereof can be of smaller and less expensive construction than in the case of conventional valves with a restoring spring.

A pneumatic control including a bus node, which is equipped with a first type communication interface and with a first type supply interface, further including a coupling module, which is equipped with the first type communication interface and with the first type supply interface and with a second type communication interface and a second type supply interface, and further including a valve module which is equipped on both coupling surfaces with the second type communication interface and with the second type supply interface, wherein a connection module is connected with the valve module, which connection module is equipped at a first coupling surface with the second type communication interface and with the second type supply interface, and which connection module is equipped at a second coupling surface with the first type communication interface and the first type supply interface.

An electropneumatic valve assembly comprises an electropneumatic pilot stage and a pneumatic power stage which is actuated by the pilot stage. Each pilot valve switches at least two power valves, and the valve assembly has a housing with an electrical signal input, with a compressed-air port, at least one vent port and at least one working outlet. The housing is layered with a pilot stage housing and a power stage housing connected along a substantially planar parting surface. At least one sealing element is between the pilot stage housing and power stage housing surrounding a control pressure region between the pilot stage housing and power stage housing. The control pressure region has two actuation regions for two power valves and has a duct-like connection with a defined flow cross section between the two actuation regions. An outlet of the associated pilot valve opens into the control pressure region.

A fluid control apparatus includes a gas line unit detachably attached to a frame. The gas line unit includes a line support member to which a fluid control device is attached. The frame includes: a first horizontal frame member; and a second horizontal frame member located below the first horizontal frame member. The first horizontal frame member includes: a hooking member extending in a left-right direction; and a lower portion which is located below the hooking member and in which a plurality of first grooves that are open to front are formed. The line support member includes: a device placement portion; and a pair of side plate portions protruding rearward from right and left edges of the device placement portion. Each of the side plate portions includes: a base portion located below the hooking member; and an upper portion located above the base portion and behind the hooking member.

A valve island has at least one valve module and an adapter module, wherein the adapter module includes a first data line and a first voltage supply line, which each extend continuously from an interface on a first front side forming an outer side of the adapter module to an interface on a second side of the adapter module pointing into the valve island. In the adapter module a circuit unit is provided, which within the adapter module is connected to the first data line and/or the first voltage supply line and from which within the adapter module an internal data line and/or an internal voltage supply line proceeds or proceed, which each extends or extend to an interface on the second side of the adapter module.

A multi-control valve unit includes a housing with built-in spools that are parallel to each other. The housing includes pilot chambers formed therein, the pilot chambers corresponding to both ends of the spools. Solenoid proportional valves are mounted to the housing, such that the solenoid proportional valves are connected to the respective pilot chambers. A hydraulic pressure generator is mounted to the housing, such that the hydraulic pressure generator is connected to the solenoid proportional valves. The hydraulic pressure generator includes an electric motor and a pump.

An electronic valve controller for an open-loop and closed-loop control of a valve island includes four or eight valve disks having pneumatic valves configured to perform a motion task. Applications for the open-loop and closed-loop control of the valve island can be loaded onto the electronic valve controller. The invention further relates to a valve assembly, which is controlled in an open-loop and closed-loop manner by an electronic valve controller, to a corresponding method, and to a system.
