Examples are provided that describe a linear hydraulic valve. In one example a linear valve comprises a sleeve with a plurality of ports spaced apart from each other at a distance. The plurality of ports are associated with a plurality of pressurized fluids. A spool comprising a plurality of openings that correspond to the plurality of ports is provided within the sleeve. The plurality of openings are spaced apart in a manner that enables alignment of a given opening of the plurality of openings to a given port of the plurality of ports based on a given position of the spool within the sleeve. The linear valve comprises an actuator for moving the spool in a forward or reverse linear motion along a longitudinal axis of the sleeve. The spool may be moved to a given position based on selection of a pressurized fluid of the plurality of pressurized fluids.

A valve device having a valve housing (10, 54, 94, 166) and fluid ports (16, 18) disposed therein, which are connected to or separated from one another in a fluid-conveying manner by means of a valve piston (22) displaceable along its longitudinal axis (24) in its various travel positions, and having at least one latching device (26, 28) for latching the valve piston (22) in at least one of its travel positions, wherein individual latching means (30, 38, 170) of said latching device, when it is actuated by an external force, take latching positions spatially different from one another, which is characterized in that, with respect to the longitudinal axis (24) of the valve piston (22), the individual latching means (30, 38, 170) of the latching device (26, 28) take positions differing from one another both in the axial and in the radial direction in the individual latching positions.

A pressure regulation valve including a multiplicity of function modules, preferably pre-mounted function modules, with a pilot stage module and an actuator module, which are firmly interconnected via a press connection, preferably exclusively a press connection, and which preferably have a central axis. A shock absorber with at least one pressure regulation valve.

Embodiments of the present disclosure provide a transmission spool valve/valve body arrangement facilitating the manufacturing of the valve body chambers accommodating the spool valves. Specifically, embodiments of the present disclosure provides a valve body having a common datum from which machining for each valve cavity formed through a particular face of a valve body can be referenced. In particular embodiments of the disclosure, a spring biases a solenoid assembly for each valve against a datum (common or otherwise). In more particular embodiments of the disclosure, the spring biases the solenoid assembly in a direction opposite to the direction of actuation of the spool valve upon actuation of the solenoid assembly. The spring bias positively displaces the solenoid assembly to the datum for precision location of the solenoid relative to the various hydraulic ports of the respective valve chamber. A variety of spring clip arrangements are provided to index the solenoid to the valve body.

A valve having a metal insert with a fluid passage formed in the metal insert. A composite valve body is disposed at least partially around the metal insert and having at least one port in fluid communication with the fluid passage with the metal insert. A valve member is partially disposed in the metal insert and operable to control the fluid flow through the fluid passage of the metal insert and parts of the valve body.

An electromagnetic and pilot-operated proportional valve with a valve slide unit (12) mounted in a valve housing (10) so as to be movable along an axial direction, which unit can be driven by an electromagnetic actuator assembly (16) provided at one axial end for the pilot-operated opening of a useful fluid inlet and/or outlet (24) of the valve housing as a response to energisation of a stationary coil (20) of the actuator assembly and interacts with mechanical force storage means (48, 50), more particularly is held in an unenergised stable axial position in the valve housing by said means, wherein the valve slide unit having a closure section (22) extending radially from one body section (30) of the valve slide unit (12) for sealing interaction with the useful fluid inlet or outlet (24) formed on a circumferential inner wall of the housing (10) interacts axially at one end, by means of the preferably cylindrical and/or coaxially extending body section (22), with a stationary guide section (40) of the valve housing to form an axial sliding bearing (62) and, at the other end, is mounted with radial play (56), wherein preferably ring-shaped sealing means (32) seal a circumferential section of the body section with radial play to the circumferential inner wall of the valve housing.

A pilot valve is provided, which comprises a valve body having a cylindrical structure, a magnetically permeable sleeve made of permeability magnetic material, and a coil assembly. The magnetically permeable sleeve is sleeved and fixed on one end of the valve body. The coil assembly is sleeved on the magnetically permeable sleeve. The coil assembly comprises an electromagnetic coil wound along the circumference of the magnetically permeable sleeve.

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.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

A solenoid valve includes a valve portion and a solenoid portion. The valve portion has a sleeve and a valve body. The solenoid portion includes a tubular coil portion, a magnetic yoke having a side surface portion and a bottom portion, a columnar plunger, a shaft, a stator core having a core shaft hole for sliding the plunger in the axial direction, and a base portion having a base shaft hole. In a radial thickness of the sleeve, a thickness of a part corresponding to an end outer peripheral surface is smaller than a thickness of a sliding portion of an inner peripheral surface of the sleeve, which is a portion on which the valve body slides.
