A method for cleaning the seat of a double seat valve is provided. The seat cleaning flow is guided to the greatest possible extent without swirling into and out of the leakage cavity, and reliably avoid a pressure-increasing, direct impact on the seat regions. The first seat cleaning flow is urged by the deflection surface radially inwards and axially towards the first closing member until it leaves the second closing member at a frontally and radially internal end of the second closing member, which end is located outside the recess. The deflection surface borders in its entirety the remaining region of the recess that is not delimited by the circumferential wall and opens out from the second closing at a front and radially internal end thereof that faces the first closing member.

DIAGNOSTIC METHOD FOR POPPET VALVES AND MEASURING DEVICE FOR CARRYING OUT SAID METHOD
The invention relates to diagnostic methods according to the preamble of the equivalent claims 1 and 2, with which the state of a poppet valve in the course of the switching cycles and/or events thereof, such as the occurrence of pressure shocks or surges during continuous operation is/are monitored continuously, the measured signals are stored and the stored measured signals are interpreted in a targeted manner and early indication of cases of damage is carried out. According to a preferred variant of the diagnostic method, said aim is achieved in that at the same time as the force-time curve of the actuating force or the reaction force (F1(t); F2(t)), a displacement-time curve (h(t)) of the displacement (h) of the at least one closing element (8*) is measured, in that the force-time curve of the actuating force or of the reaction force (F1(t); F2(t)) and the displacement-time curve (h(t)) are combined with each other and used to determine a force-displacement curve of the actuating force or the reaction force (F1(h); F2(h)), in that the current force-displacement curve of the actuating force (F1(h)) or the reaction force (F2(h)) of a switching cycle, in each case determined over the operating period or lifetime of the poppet valve (100), is compared with an earlier, stored curve, in that deviations are determined from the comparison, in that, within a predefined tolerance range for said deviations, the latter are accepted, and in that, when said deviations exceed the predefined tolerance range, a message and/or a control signal is/are generated.

ACTUATING DEVICE FOR A ROTATABLE CLOSURE PART OF A VALVE
The invention relates to an actuating device 1 for a rotatable closure part of a valve 100, in particular a pneumatically or hydraulically actuable rotary drive for a disc valve or throttle flap valve, according to the preamble of claim 1 or 2. The invention is based on the problem of providing an actuating device of the generic type, which actuating device has high stability in the region of the driving connection between the drive piston and drive shaft, the restoring spring of which actuating device is subjected to no additional torsional loading by the walls delimiting it at both sides, and which actuating device has stroke-independent, direct rotational angle limitation with the greatest possible accuracy. This is achieved according to a first solution • in that the driving connection (4.2.2/5.1a; 4.2.2a/5.1a*) is designed either in the form of a polygonal shaft-hub connection or in the form of a spline hub (4.2.2), which has a straight-toothed spline groove formation (4.2.2a), formed on the drive piston (4), and a shaft head (5.1), which is of complementary design to the spline hub (4.2.2) and which is formed, in the engagement region, as a spline shaft (5.1a) with a spline profile (5.1a*), which shaft head (5.1) forms the end of the drive shaft (5), • in that the shaft head (5.1) is mounted in a floating fashion in the first housing end surface (2.2) and engages in a floating manner into the driving connection (4.2.2/5.1 a; 4.2.2a/5.1a*) in the drive piston (4), • and in that the shaft head (5.1), via the means (9) arranged on the first housing end surface (2.2) and in the connecting region between the latter and the housing jacket (2.1), is subjected to stroke-independent direct delimitation of the rotational movement thereof about the axis of rotation (A).

Device for the piping of process systems in the food and beverage industry
A piping system for food and beverage process plants connecting a tank and process assembly to a pipe system via double seat valves mix-proof in the seat including valve distributor trees and the double seat has two serially disposed closing members with open and closed positions, the closing members delimiting a leakage cavity with a connection path to the surroundings of the double seat valve. A first closing member comes in sealing contact at a second closing member and transfers the second closing member into a sealed position. The second closing member having a hollow rod and a seat seal.
A device for driving a double seat valve with two closing elements arranged in series and displaceable with respect to each other. A sleeve-shaped fourth drive piston pressurized by pressure medium, sealingly embraces a second drive piston on the circumference and can engage a catching connection in the direction of a first drive piston, wherein a second drive piston is adapted to be axially displaceable in a limited manner in both directions with respect to the first drive piston and in each case against the force of a second spring.
