An electronic expansion valve and a manufacturing method therefor, a thermal management assembly and a cooling system are provided. The electronic expansion valve includes a valve core assembly, an electronic control part and a stator assembly. The valve core assembly includes a valve base, a valve core and a rotor assembly, wherein the valve base is provided with a valve port, and the valve core moves relative to the valve base to change the degree of opening of the valve port. The electronic control part controls the stator assembly, and the rotor assembly drives the valve core to move. The electronic expansion valve further includes a sensor, the electronic control part includes an electronic control board, and the stator assembly and the sensor are both directly electrically connected to the electronic control board. The thermal management assembly and the cooling system both include the electronic expansion valve.

A holder for a magnet of a magnet sensitive regulating valve position detector of a regulating valve of a process plant. The detector can include a shaft turnably movable supported in a housing of the detector, the shaft defining a turning axis oriented parallel to a turning spring supporting itself at the housing, and having a lever arm being turnably fixed with the shaft, the lever arm being coupled to the regulating valve such that a regulating valve stroke movement by the lever arm is transferable into a shaft rotation movement. The holder includes a holding fixture to interlockingly hold the magnet, a fixing section connected to the holding fixture to fix the holder at the shaft turnably fixedly, and a support connected to the holding fixture and the fixing section to latchingly support the rotational spring to generate a rotational spring force on shaft rotation movement.

An annulus pressure release system includes a gas metering valve assembly having a fluid pathway. The gas metering valve assembly includes a pressure sensor configured to be fluidly coupled to an annulus and to output a sensor signal indicative of a fluid pressure within the annulus. The gas metering valve assembly also includes an electronically actuated adjustable control valve disposed along the fluid pathway and a electronically actuated two-position valve disposed along the fluid pathway. Furthermore, the gas metering valve assembly includes a flow controller. The flow controller, in response to determining the fluid pressure exceeds a threshold pressure, is configured to output a first control signal to the electronically actuated two-position valve indicative of instructions to open the electronically actuated two-position valve, and to output a second control signal to the electronically actuated adjustable control valve indicative of instructions to adjust a flow of fluid through the fluid pathway.

A ball valve system includes a body having an upstream end and a downstream end and a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position. The ball valve assembly includes a stem movable in an actuation direction substantially parallel to the vertical axis, the stem including a recess at a proximal portion of the stem, a guiding member extending within the recess of the stem, the guiding member being configured to prevent rotation of the stem or cause rotation of the stem, and a lubrication port in fluid communication with the recess.

A housing assembly for a manifold includes a first housing with an inlet and a plurality of outlets, a second housing, and a valve retainer engaged with the first and second housings. The valve retainer includes a retention plate defined between first and second surfaces, a plurality of slot walls extending from the first surface, and a protruding edge that extends from a flanged lip and surrounds the plurality of slot walls. The retention plate defines a plurality of slots corresponding to the plurality of slot walls. The first housing may define a groove that receives the protruding edge, and the second housing may include a rim that engages the flanged lip of the valve retainer. Valve housings including first and second mating structures separated by wall segments may be positioned in outlets of the first housing and corresponding slots of the valve retainer.

A flow control valve may include a housing including a fluid-flow channel, a valve seat including a valve hole and positioned in the fluid-flow channel, an electric motor disposed in the housing, and a valve body configured to be axially moved toward and away from the valve seat by the electric motor via a feed screw mechanism. The valve body includes a straight projecting portion. The projecting portion is configured to be positioned in the valve hole in an initial valve body lifting range in which a lift distance of the valve body relative to the valve seat is not greater than a predetermined lift distance.

A device for controlling a flow and distributing a fluid, in particular a refrigerant, in a fluid circuit. The device exhibits a housing with connections for connection to fluid lines that are connected to one internal volume of the housing via a pass-through opening, and one valve element that is arranged in the internal volume of the housing and exhibits a drive element for moving the valve element relative to the housing. The valve element exhibits one pass-through opening and is mounted in such a way that it can be moved linearly in the axial direction along a longitudinal axis such that a passage for the fluid is opened between a first connection produced as an inlet and a second connection produced as a primary outlet or a third connection produced as a secondary outlet.

A proportioning valve for a reverse osmosis system that controls the production of product water by the differential pressure across the purification membrane. By sensing increasing tank pressure to actuate the proportioning valve, the flow of waste water is restricted. Placement of seals within the cavity of the valve, as well as placement of waste water inlet and outlet ports, protects tension components that provide reverse tank pressure from waste water exposure. A needle valve assembly responsive to an actuating assembly that senses tank pressure removes the need for an inlet tank water port while restricting water flow.

A valve drive with a snap function includes a rotary drive input, a lead screw connected to or formed by the rotary drive input, a slide in threaded engagement with the lead screw to form a screw thread, the slide being mechanically connected or connectable to a valve body and being movable in the direction of a longitudinal axis. A bearing housing is provided in which the lead screw is mounted so as to be rotatable about the longitudinal axis and stationary in the direction of the longitudinal axis. The bearing housing is held against a displacement along the longitudinal axis by a releasable locking device, countering the preload force of a snap spring.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.
