A valve apparatus includes a housing including an inlet and first and second outlets, through which water introduced through the inlet is discharged, a first orifice including an opening communicating with the first outlet and a second orifice including an opening communicating with the second outlet, the first and second orifices being received in the housing, a first plunger for opening and closing the opening of the first orifice; and a second plunger for opening and closing the opening of the second orifice. Each of the orifices includes a rib surrounding the circumference of each of the plungers in a state in which each of the plungers closes the opening of each of the orifices.

A pneumatic ABS valve device for a pneumatic brake system of a vehicle comprises a check valve mechanism for enabling a supply air flow from a supply port to a delivery port and blocking an air flow in the reverse direction. The check valve mechanism comprises a quick release insert disposed in an insert chamber, the quick release insert being placeable in a basic position for providing a chamber passage in the insert chamber enabling the supply air flow. The quick release insert is displaceable by an air pressure difference from the basic position into an activated blocking position, in which the chamber passage is at least diminished with respect to its basic position, in order to block an air flow from the supply port to the delivery port and enabling exhaust air flow.

The invention relates to a control valve (10) for a process plant, comprising an actuator (16) which is connected to, and spaced from, a valve body (12) of a valve unit (11) via a yoke (14), the valve body (12) having a housing flange (32) which is detachably connected to the yoke (14), with the valve body (12) having an inlet (20) and an outlet (22) adapted to allow the flow of a process fluid therethrough, which inlet (20) and outlet (22) are each arranged in a fluid connection region (18, 19), and with an actuating member adapted to be displaced by the actuator (16) for controlling the flow rate of the process fluid being arranged in the passage (24) from the inlet (20) to the outlet (22). The invention is characterized in that the housing flange (32) connected to the yoke (14) has at least one recess (44) as well as a yoke fastening region (33), with the yoke fastening region (33) being formed as a bolt hole circle (34) with radially arranged connecting holes (36).

An example valve includes: a pressure compensation spool configured to be subjected to a first fluid force of fluid received at an inlet port of the valve; a sleeve having a cavity and at least one throttling cross-hole; a throttling spool disposed in the cavity of the sleeve and configured to be axially movable therein, wherein the throttling spool blocks the at least one throttling cross-hole when the valve is unactuated; and a pressure compensation chamber, wherein when the valve is actuated, the throttling spool moves in the proximal direction to form a throttling flow area between a distal end face of the throttling spool and an edge of the at least one throttling cross-hole, allowing fluid flow from the inlet port to the pressure compensation chamber, thereby causing a second fluid force to be applied on the pressure compensation spool, allowing flow to an outlet port of the valve.

A valve cartridge for a solenoid valve, includes a capsule, a magnet armature which is guided in a movable manner within the capsule, a valve insert, and a valve body which has a main valve seat. The magnet armature, which is moved by a generated magnetic force, acts within the valve insert on a closing device, which has a plunger and a sealing element. The sealing element, in the currentlessly open state, opens up the main valve seat and, in the electrically energized, closed state, projects sealingly into the main valve seat of the valve body. The plunger and the sealing element are formed as separate components, and the sealing element is guided axially and/or radially by a guide device, which includes multiple guide balls arranged between the sealing element and an inner wall of the valve insert.

An actuator for a hydraulic stroke or pressure control valve for a motor vehicle, the actuator including a magnetisable actuator housing that envelops a magnet coil; a pole group arranged in a receiving opening of the actuator housing, wherein the pole group includes a pole core and a pole tube, wherein an axially movable armature is arranged in an inner cavity of the pole group, wherein the armature is configured to axially move a piston of the hydraulic valve by a pin that is supported axially movable in the pole group, wherein the actuator is configured to perform an anti-stick function and a contact damping function, wherein the pin directly contacts a first armature face of the armature that is oriented towards the pin, and wherein the pin is configured axially movable relative to the armature.

A valve includes a housing, a solenoid arranged in the housing, a pin movable by the solenoid, a piston connected to the pin, and a seal. The piston is made of metal and the seal made of a different material than the piston. The seal is arranged in a crown region of the piston.

The invention relates to a solenoid valve or an aircraft anti-ice system. The solenoid valve comprises: a solenoid; a yoke arranged to be actuated by the solenoid between a first yoke position and a second yoke position; and a plunger arranged to be actuated between a first plunger position and a second plunger position to control fluid flow between fluid channels. The plunger comprises a magnetic element proximate the yoke. There is a gap between the plunger and the yoke when the yoke is in the second yoke position, so that magnetic force acting on the magnetic element of the plunger urges the plunger to the second plunger position.

A variable-capacity compressor control valve that can efficiently cancel the influence of the refrigerant pressure acting on a main valve element and avoid increase in complexity of the structure and size of the control valve is provided. A pressure equalizing passage is provided which is adapted to guide a pressure Pc in a crank chamber acting on the lower end of a main valve element to a pressure-sensitive chamber so that the pressure Pc in the crank chamber acts on the upper end of the main valve element. When an electromagnetic actuator or a solenoid portion thereof is not supplied with current i.e., when a valve orifice is fully open, the introduction of a suction pressure Ps from Ps inlet/outlet ports Ps inlet/outlet chamber into the pressure-sensitive chamber is stopped, and the pressure Pc in the crank chamber is introduced into the pressure-sensitive chamber via the pressure equalizing passage so that the pressure Pc in the crank chamber acts on the upper and lower ends of the main valve element.

An actuator for a hydraulic valve for a cam phaser, the actuator comprising a magnetisable actuator housing that envelops a magnet coil; a pole group that is arranged in a housing receiver opening of the magnetisable actuator housing, wherein the pole group includes a pole core and a pole tube, wherein the pole core and the pole tube are connected by a connection bar and the pole core is connected with the connection bar by a pole core cone, or the pole tube is connected with the connection bar by a pole tube cone, wherein an armature is received axially movable in an inner space of the pole group.
