A shower control system has a controller and a control panel. The control panel includes a knob. The top surface of the knob has an inner ring and an outer ring; the outer ring has outlet buttons corresponding to a first outlet and a second outlet; when the outlet button is touched, the circuit of the controller sends a signal to the electromagnetic valve to open the first outlet or the second outlet; the inner ring is disposed with a display screen with a temperature displaying area, a volume displaying area, a temperature adjusting mode icon, a volume adjusting mode icon and a lock mode icon; when the knob is long pressed, the control panel is open, the inner ring lights up; the temperature displaying area, the volume displaying area of the displayer screen respectively displays the temperature and volume last used, and the lock mode icon is selected.

A three-port fluid control valve and a valve assembly using the fluid control valve are provided herein. The valve includes a first inlet, a second inlet, and a sealing element to selectably open one inlet to fluid communication with an outlet and to close the other inlet to fluid communication with the outlet. The valve system includes an actuator, for example a solenoid, to provide accurate and responsive control of the position of the sealing element.

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 for a hydraulic circuit includes an actuator unit and a valve unit. The actuator unit comprises an electromagnetic circuit comprising an armature which moves in a translational manner, a core, a coil carrier, a coil configured to be energized, and a flux guiding device. The coil is arranged on the coil carrier. The valve unit comprises a valve housing comprising a transverse bore which serves as a first control chamber pressure port, a regulating slide mounted in the valve housing, the regulating slide being configured to move axially, a first outlet port, an inlet port, and a second control chamber pressure port arranged between the inlet port and the first outlet port.

The decoking control valve includes a piston, a cylinder, and a hydraulic rod seal at the outlet ports. The piston can move translational inside the cylinder along a fixed direction. The cylinder houses the hydraulic rod seal in a groove of the cylinder that places the hydraulic rod seal next to the piston. The hydraulic rod seal has a seal ring in contact with the piston, and the seal rings are activated. As the piston translates within the cylinder, the seal ring will activate at one outlet port and allow fluid to flow out of another outlet port.

A directional control valve has a first fluid path extending between first and second ports and a second fluid path between second and third ports. A spherical valve member moves between an open position in which the valve member is displaced from a first valve seat so that the first fluid path is open and is sealed against a second valve seat so that the second fluid path is closed and a closed position in which the valve member is sealed against the first valve seat so that the first fluid path is closed and displaced from the second valve seat so that the second fluid path is open. The valve member is biased towards the closed position by opposed first and second biasing members of unequal loading. An actuator can move the valve member from the closed position to the open position against the unequal loading.

A double-solenoid directional control valve comprising a valve body and a valve spool within the valve body, where the valve spool is configured to move within the valve body between a first position, a second position and a third position, where the third spool position lies between the first and second spool positions. In certain embodiments, the spool is maintained in the first and third positions by energizing at least a first or a second solenoid actuator, and where the spool is maintained in the second position by de-energizing both solenoid actuators.

A jet valve spool includes: a spool housing on which is provided with a cold water port and a hot water port; a spray nozzle arranged in the valve core shell and having a cold water inlet of the spray nozzle and a cold water outlet of the spray nozzle, with the cold water inlet and the cold water outlet being in communication with a cold water channel of a valve by means of the cold water opening; and a spray needle which can be assembled inside the spray nozzle, can form a cold water inflow space with an inner chamber of the spray nozzle, and form a cold water jetting outlet with the cold water outlet of the spray nozzle, wherein the position of the spray needle in the axial direction of the jet valve core is fixed, and the position of the spray nozzle in the axial direction of the jet valve core is adjustable.

A pneumatic system for operating a hydraulic valve is provided. The system may include: a first piston set; a first connector attached to the first piston operably connecting the first piston; a first spring biasing the first piston to move in an axial direction; a second port in the first housing; a second piston set with in a second cavity defined by a second housing; a second connector attached to the second piston, a second spring biasing the second piston to move in an axial direction; a first port in the second housing; and a second port in the second housing configured to provide fluid communication with in the second cavity at a second end of the second piston.

A valve assembly for dispensing a confectionary product has an inlet (70), a first outlet (72), and a second outlet (90). The assembly has a valve member (80) shiftable between: a first condition providing communication between the inlet and the first outlet; and a second condition providing communication between the inlet and the second outlet.
