摘要： The invention relates to a process valve (10) comprising a valve seat (14), a flow restrictor (12), a valve rod (16) and a drive unit (18) acting thereon, with a force measuring device (20, 44) being connected between said drive unit (18) and said flow restrictor (12). The invention is characterized in that said force measuring device (49) includes a spring (30, 46), and said force measuring device (29, 44) comprises a travel measuring device (38, 42, 50, 52) so as to allow the force acting on it to be determined based on the change in the deflection of the spring (30, 46) caused by the force acting on it.

摘要： 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.
