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 is composed of a first and a second leg which extend at an angle with respect to each other such that the two legs delimit a receiving space for the valve modules on two sides, a fluid area being provided on the first leg which has a fluid connection face formed on an inside of the first leg which is turned towards the second leg and on which fluid connections are provided which communicate with fluid connections of the valve modules. All fluid connections of the valve modules communicate with fluid connections of the fluid connection face. An electrical area in which electrical connections communicating with electrical connections of the valve modules are provided is provided on the second leg.

A solenoid valve manifold (10) includes a connector member (70) that is formed by integrating a base portion (71) with a first connector portion (80) configured to electrically connect a first conductive member (52) to a circuit board (41) and a second connector portion (90) configured to electrically connect a second conductive member (62) to the circuit board (41). The base portion (71) has a through-hole (72). The base (30) includes two engagement projections (46). The base portion (71) is elastically deformable in a direction intersecting an insertion direction when the two engagement projections (46) are inserted into the through-hole (72). The connector member (70) is configured to be attached to the base (30) when a part of the base portion (71) around the through-hole (72) is engaged with the two engagement projections (46).

An air suspension system, comprising a manifold, defining a first and second port, each port defining a receiving region at the second end, wherein the first and second ports are arranged in a common plane, a channel intersecting the first and second port, a cavity intersecting each port, and a pressure sensor port, positioned between the first and second port, defining a sensor insertion axis normal to the common plane, the pressure sensor port separated from the first port, the second port, and the channel by a thickness; a first and second solenoid valve, each solenoid valve arranged within the cavity and coaxially arranged with the first and second ports, each solenoid valve comprising a connector; a pressure sensor arranged within the pressure sensor port, the pressure sensor comprising a connector; and an electronics module arranged parallel the common plane, the electronics module configured to electrically couple to the connectors.

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.

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 fluid valve manifold has an electrical conduit for receiving a circuit board assembly that actuates a plurality of valve units. The circuit board assembly is reversibly and rotatably mountable to a first position or second position in the electrical conduit such that a respective set of first electrical connectors at a first end or a second set of electrical connectors at a second end opposite that of the first end may be in position to receive electrical signals through the respective connectors. When in one position, the circuit board assembly is able to serve a single solenoid valve unit. When in a rotated second position, the circuit board is able to serve a double solenoid valve unit.

A pneumatic control system includes a manifold that defines: a channel for conveying a fluid, a discharge port, a drain port, and an expansion chamber defining a chamber axis. The discharge port defines a flow axis extending between a first end and second end and a receiving region at the second end. The pneumatic control system also includes a filter assembly with a filter member disposed in the expansion chamber, and an actuator configured to selectively control fluid communication between the channel and the discharge port. The chamber axis is substantially coplanar with the flow axis. A filter cap assembly includes a filter cap body enclosing an end of the expansion chamber and selectively removable from the manifold to provide access to the filter assembly. A purge valve body is configured to selectively control fluid flow between the expansion chamber and the drain port.

An exemplary valve bank and/or modular control valve having a valve body, a valve member movable in a fluid flow of the valve body to control flow of fluid, and an onboard electronic controller that is operably mounted to the valve bank or valve body. The onboard controller is operably connected to at least one actuator of the valve, which is configured to control movement of the valve member in response to commands from the onboard controller. The onboard controller may provide diagnostics, feedback and/or control of the control valve, such as via inputs from one or more sensors that may be included in the valve. The modular control valve may be used with conventional non-intelligent valve banks to thereby impart smart diagnostics and/or feedback into the valve bank in a plug-and-play manner. A communications interface may be provided in the control valve to interface and communicate with an upper-level PLC controller.
