Abstract: The invention relates to a pinch valve that includes: a main body having a receiving space for a tube section, wherein the receiving space comprises a lateral opening of the main body; a counter-bearing section for a compressor that moves along a actuating axis; and a closure element which is movably fastened to the main body and which is movable relative to the main body between a first position, in which the closure element closes the lateral opening of the main body at least in sections, and a second position, in which the closure element exposes an insertion opening for the tube section.

Abstract: The invention relates to a valve body for a process valve, wherein an interior space of the valve body connects at least two ports to one another in a fluid-conducting manner, wherein at least one partition wall separates adjacent flow chambers of the interior space from one another, and wherein an outer shell and the at least one partition wall, at least in a blocking portion of the valve body extending essentially perpendicularly to a blocking axis, are made of a flexible material.

Abstract: A diaphragm valve with a drive housing and with a drive subassembly arranged in the drive housing is proposed, for controlling a process fluid by means of a diaphragm. The diaphragm valve comprises a pretensioning subassembly for the arrangement between the drive subassembly and the diaphragm. A first spring element holds the drive subassembly in a pretensioned state before introduction into the drive housing. A second spring element holds the pretensioning subassembly in a pretensioned state before introduction into the drive housing.
