The disclosure relates to a valve, in particular a solenoid valve, having an optimized seat geometry. The valve comprises a sealing element and a valve seat which surrounds a passage opening having a nominal diameter, the valve seat having on a side facing the sealing element a closed circumferential rounding which, in a cross-sectional plane which extends through a central axis of the passage opening, has a seat radius, a distance of a radius center of the seat radius from a wall inner side defining the passage opening being smaller than the seat radius.

Valve having an optimized seat geometry

A valve linear drive provided for connection to a valve body having a valve seat includes a drive housing, a valve closure member, an actuator, and a spring device. The valve closure member is adjustable along an adjustment axis (V) between an open position and a closed position by means of the actuator and an actuating means. The spring device urges the actuating means into the open position or into the closed position. Further, the spring device includes a plurality of springs and a receiving unit for the springs. Here, each spring has its own spring chamber formed in the receiving unit, in which the associated spring is inserted. Furthermore, a valve having such a valve linear drive is provided.

Valve linear drive and valve

A closed-loop control valve module for closed-loop controlling a fluid flow is described, which comprises an electrical valve actuator motor, wherein a valve spindle comprising a frustoconical sealing section is displaceable by means of the valve actuator motor along a valve spindle axis and the frustoconical sealing section, depending on the position of the valve spindle, releases or separates off a flow channel connecting a fluid inlet and a fluid outlet. A pressure compensation channel is provided which, at least in the closed state of the closed-loop control valve module, connects an end of the valve spindle opposite the valve actuator motor to a pressure compensation area or the fluid inlet in terms of flow.

Closed-loop control valve module

A solenoid valve has a housing, which has a fluid inlet and a fluid outlet, and an electromagnetic drive, which comprises a solenoid with a fixed core and a movable armature, wherein the armature interacts with a valve seat. A pressure compensation chamber which is bordered by a membrane is formed in the armature, wherein the pressure compensation chamber is in fluid connection in terms of flow with the fluid inlet by means of a pressure compensation channel.
