A control device for at least one hydraulic working section (A, B), which can be connected to a pressure supply source (P) and a return flow (T) via a hydraulic supply circuit and to a control valve (34) supplied with a pilot pressure. The device includes an emergency shutdown system (32) having a pilot solenoid valve (16) and an additional valve (14). Both the hydraulic energy flow from the pressure supply source (P) to at least one of the respective working sections (A, B) and the pilot pressure supply to the control valve (34) can be suppressed by the pilot solenoid valve (16) via the additional valve (14).

Method for connecting, in a fluid manner, a system (100) for fluid communication comprising a first (10) and a second (20) fluid valve and comprising the following steps:providing a first (10) and a second (20) fluid valve, providing a first pipe (60), inserting each of the ends (61, 62) of the first pipe (60) into each of the fluid valves (10, 20) in order to form a fluid assembly (100), providing a compression means (1) comprising two ends (2, 3), positioning said two ends (2, 3) of said compression means (1) on either side of said fluid assembly (100), applying a compression force onto said fluid assembly (100) via the compression means (1).

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.

Gas supply assemblies and reactors systems including the gas supply assemblies are disclosed. An exemplary gas supply assembly includes a vessel, a valve plate, a housing encasing the vessel and the valve plate, a gas feedthrough having a first end interior of the housing and a second end exterior of the housing, and one or more valves attached to the valve plate, wherein at least one valve is fluidly coupled to an interior of the vessel. The assemblies can further include a removable gas line having a first end coupled to the at least one valve and a second end coupled to the gas feedthrough. Additionally or alternatively, a gas supply assembly can include one or more valve plate leveling devices coupled to the valve plate.

A solenoid valve island having a base body that includes a housing for a respective solenoid valve, a main feeding duct that is in fluid communication with the housing to supply compressed air entering the solenoid valve and that is provided with an inlet mouth for connection with a source of compressed air, a main collection duct in fluid communication with the housing to collect air leaving the solenoid valve and a discharge mouth for discharging the collected air, a hollow seat in which an electric or electronic supply and control circuit of the solenoid valve is housed and includes an opening at each housing for the electric connection, through it, of the respective solenoid valve with the electric or electronic supply and control circuit, where the electric or electronic supply and control circuit has a male or female type power supply and signal transmitting connector that is partially housed in the hollow seat of the base body and that can be coupled with a corresponding end connector of a cable for the connection of the electric or electronic supply and control circuit to a remote supply and control unit, the corresponding end connector being respectively female or male.

A control device is disclosed for at least one hydraulic working section (A, B), which can be connected to a pressure supply source (P) and a return flow (T) via a hydraulic supply circuit and a control valve (34) supplied with a pilot pressure, the device comprising an emergency shutdown system (32) having a pilot solenoid valve (16) and an additional valve (14). Said control device is characterised in that both the hydraulic energy flow from the pressure supply source (P) to at least one of the respective working sections (A, B) and the pilot pressure supply to the control valve (34) can be suppressed by means of the pilot solenoid valve (16) via the additional valve (14).

A method is described for manufacturing a three-dimensional product, in particular a hydraulic element, the method encompassing at least the following method steps: Providing a first section of the product to be manufactured, which includes at least one first connection point for a second section of the product to be manufactured; and producing the second section by an additive manufacture in which the at least one first connection point of the first section is used as a substrate for the additive manufacture of the second section.

A hydraulic valve assembly for a work vehicle includes a fan and brake function module. A first pump supplies hydraulic pressure to a fan circuit and to first and second service brake circuits of the vehicle. A second pump supplies hydraulic pressure to a steering and work function module that in turn supplies hydraulic pressure to a steering circuit and a work function circuit of the vehicle. The hydraulic valve assembly may also include a work control module and an auxiliary module. The modules of the hydraulic valve assembly are separably connected together via interface surfaces.

A valve assembly has a valve housing with a hole therein. A valve spool is slidably received directly into the hole of the valve housing with no sleeves or seals interposed therebetween. Preferably, the valve housing and valve spool may be made from hardened stainless steel, preferably hardened 440C stainless steel. Preferably the manifold block has integrally formed manifold section and valve housing section.
