A valve assembly includes a first body portion, a second body portion secured to the first body portion, and a cage positioned between the first body portion and the second body portion. The cage has a generally cylindrical body, a bore formed longitudinally through the body, a top surface, an opposing bottom surface, an exterior surface, an opposing interior surface, and an integral, unitary annular flange extending from the exterior surface and around a perimeter of the cage. The annular flange includes a first surface configured to engage the first body portion to form a seal between the cage and the first body portion and a second surface configured to engage the second body portion to form a seal between the cage and the second body portion.

Vacuum machining system (1), comprising a vacuum chamber (10) and a vacuum regulating valve (20). The vacuum valve (20) has a first valve seat (21a), which has a first valve opening (22a) defining a first opening axis (O) and a first sealing surface extending around the first valve opening (O), and a first valve plate (23a) with a first contact surface corresponding to the first sealing surface. The vacuum machining system further comprises a drive unit (30), which is designed in such a way and is coupled to the first valve plate (23a) in such a way that the latter can be moved at least from an open position to a closed position and back again. The first valve seat (21a) is arranged within the vacuum chamber (10) and divides the vacuum chamber (10) into a main process chamber (11) for machining the substrate and into a secondary process chamber (12). The first sealing surface extends orthogonally to the first opening axis (O) and points in the direction of the secondary process chamber (12). The first valve plate (23a) is movably arranged in the secondary process chamber (12).

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 coolant valve for a motor vehicle. The coolant valve includes a housing with an inlet and an outlet, a valve seat which surrounds a flow cross-section formed between the inlet and the outlet, and a control body which is placeable on and liftable off the valve seat via an actuator. The control body has through-going bores via which the inlet is continuously connected to a chamber on a side of the control body which faces away from the inlet, a first annular protrusion which axially extends towards the valve seat and via which the control body is placed on the valve seat, a wall which extends radially between the first annular protrusion and the through-going bores, and an axial groove which extends in a circumferential direction and which is delimited radially to an outside by the first annular protrusion and radially to an inside by the wall.

An actuator includes a sliding body moveable along a guide between a rest position and a retracted position, a spring resting on a support body and acting to exert a bias force urging the sliding body to the rest position, and a SMA wire having opposite ends being mechanically and electrically connected to a respective one of two stationary contacts and forming a loop between the opposite ends which is connected to the sliding body, wherein the SMA wire is arranged to, when activated by electric energy supply, pull the sliding body away from the rest position to the retracted position, wherein the guide is fixed to a first end portion, the support body is fixed to an intermediate portion, and a contact holding body, in which the two contacts are incorporated, is fixed to a second end portion of a mounting bar.

A valve assembly comprising a valve guide and one or more weights coupled to and/or integral with the valve guide. The valve assembly may further comprising a valve body and a valve stem connecting the valve body to the valve guide. The valve assembly may be disposed in a fluid end of a positive displacement pump that is operated to flow a wellbore servicing fluid into a wellbore.

A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.
