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).

An air release structure of an integrated flow control mechanism includes a flow control housing, a radiator nipple provided on an upper portion of the flow control housing and forming a bypass passage portion together with the flow control housing, a float provided in the bypass passage portion and an elastic member to support the float elastically and to selectively open the bypass passage portion.

A fluid control device, capable of acquiring data related to an internal operation of a device, is provided. The Fluid control device V includes a bonnet part installing sensors for detecting the internal operation of the fluid control device and a valve body containing the bonnet part inside, and the valve body has a recess for containing the bonnet part and a slit, leading a communication cable connected to the sensors to the outside, opening one end on an opposite side of a base where a flow path is formed, and penetrating from an outside to the recess.

A filling level sensing device for a liquid reservoir, in particular for a compensation tank of a vehicle brake system, includes at least one float, at least one sensor element connected to the at least one float, and at least two sensors for detecting the position of the at least one sensor element. The float may be designed to come into contact with the liquid in the liquid reservoir. At least one of the two sensors may sense a change in the filling level of the liquid reservoir depending on the position of the at least one sensor element relative to the at least two sensors.

A fluid control apparatus includes a block elongated in a longitudinal direction and having a predetermined width, an internal flow channel formed inside the block so as to extend in the longitudinal direction, a first control valve mounted on the block, a second control valve mounted on the block at a position downstream of the first control valve. In the fluid control apparatus, the internal flow channel has a first outflow channel connected to a first outlet of the first control valve through which a fluid flows out thereof and also has a second inflow channel connected to a second inlet of the second control valve through which the fluid flows thereinto. In addition, the first outflow channel and the second inflow channel are disposed so as to overlap each other at one point as viewed in the width direction through the block.

A valve includes a housing with at least one inlet and at least one outlet; a valve member located within the housing and being moveable between different positions for controlling, in use, the flow of a fluid from an inlet to an outlet of the valve; wherein the valve further includes at least two spaced-apart valve seats in which the valve member is seated so as to form a cavity bounded by the valve seats, an exterior surface of the valve member and an interior surface of the housing; a first conduit extending between the exterior of the housing and the cavity; and a second conduit extending between the cavity and a bore of the valve member, through which conduits, in use, a purge gas can be introduced into the cavity and bore.

A fluid flow rate sensor, which may also be the basis of a valve for a fire suppression system, uses a sensing arm to convey motion of an obturation body or a valve closing member to a sensor system which evaluates the motion and generates a calibrated measure of the flow rate and/or an alarm signal in response if warranted. The obturation body and the valve closing member are capable of both rotation and translational motion, both of which are sensed using the sensing arm. The sensor system is isolated from the fluid within the valve.
