The invention relates to a valve apparatus for a gaseous medium, having a valve body with an opening which can be flowed through in the flow direction by the medium and is delimited by way of a circumferential face in the valve body. An orifice is arranged in a gap within the valve body such that it can be displaced perpendicularly with respect to the flow direction, in order to influence the flow through the opening. The gap divides the circumferential face into an inlet-side and an outlet-side part circumferential face. The outlet-side part circumferential face has a first edge which faces the orifice and a second edge which faces away from the orifice. The first edge is assigned at least one geometrical feature which is configured to make the first edge non-uniform.

Valve device

The invention relates to a valve mechanism (') for controlling a fluid, comprising a housing (&#x2032;) that has a fluid duct (), further comprising a valve body () that is mounted on the housing () so as to be adjustable between an open position in which the valve body allows the fluid (F) to flow through the fluid duct () and a closed position in which the valve body fluid-tightly seals the fluid duct, and comprising a membrane-like sealing element () which is secured to the housing () at a first end portion () and to the valve body () at a second end portion. In the open state of the valve body (), a side of the sealing element () that faces away from the fluid duct () rests against a wall section () between the two end portions ().

Valve mechanism for controlling a fluid, in particular an abrasive high-viscosity material

A regulating slide valve apparatus having a housing which forms a duct through which a gaseous or liquid medium can flow having an inlet longitudinal portion, an outlet longitudinal portion, and an adjustable regulating element for varying the flow cross section of the duct and adjusting the throughflow rate. A seat ring element is provided in the duct, the regulating element has a first longitudinal portion which has a circular cross section with diameters that vary in the longitudinal direction, and the regulating element is adjustable in the longitudinal direction of the duct along an adjustment travel. In a closure position the regulating element lies against the seat ring element and closes the duct and, in an open position, forms an annular gap through which flow can pass, with the seat ring element. The varying diameters along the first longitudinal portion of the regulating element are configured such that the change in the cross-sectional area through which flow can pass, of the annular gap with the adjustment of the regulating element in the longitudinal direction, is such that the volume flow through the annular gap varies approximately linearly with the adjustment of the regulating element along the adjustment travel.
