The invention relates to a process for a control valve having a valve seat and a throttle element, which throttle element has a sealing edge for sealing the valve seat, and furthermore a first opening area and a second opening area, which throttle element can furthermore be positioned relative to the valve seat by a positioning motion such that the first opening area will be effective in a first opening position thereof and/or the second opening area will be effective in a second opening position thereof, characterized in that a sealing element is arranged on the throttle element and/or the valve seat such that the throttle element will pass over a sealing position as it transitions from the first opening position to the second opening position, in which sealing position the first opening area will be effective and the second opening range will not be effective.

Control valve

The invention refers to a cage valve comprising a valve cover () and a valve cage, which latter comprises a retaining element () and a plurality of throttle elements () which are designed in the form of a hollow section. The invention is characterized in that the valve cage is connected to the valve cover ().

Cage assembly with throttle rings

A drive unit is designed as a diaphragm drive with return springs for shifting an associated actuator, connected by a diaphragm plate and a driving diaphragm, into a safety position. The drive unit also includes actuating springs that are held in a compressed state by two nested sleeve-shaped counterbearings that are locked during normal operation and located coaxially with respect to the return springs. The lock is formed by a temperature-dependent joint.
