From the other valve, however, is via the measuring line the full inlet pressure continue to act on the measuring element and then move it.

Case of one of the valves by field circuits or by any other disturbance, then the pressure difference that forms against the consumer is also effective here, against your valve that is still in operation and also in In this case, the disconnection means are actuated via the measuring element ο ■■ ■ '

With simple straight-way valves, i.e. not in a double arrangement, If necessary, you can proceed in such a way that the full control pressure from the inlet is applied to one measuring element side is, while there is an additional auxiliary choke that in the normal Schalta bellungen the measuring element in the middle position transferred * This throttle is switched off via an additional control unit depending on the movement of the locking pieces or an bypass valve is opened «so that no switching on the Measuring element takes place.

In a further embodiment it would also be conceivable for one side of the measuring element to decrease the pressure on the valve seat and in the area of the valve stem itself, provided a so-called piston-like partial pre-sealing is provided.

The exemplary embodiments show how the invention can be carried out in detail, with the cures essential for it in the drawing:

Figure 1 - a control in section of

Individual valves that are triggered together, whereby as valves, normal straight-way valves are used,

Figure 2 - two single valves with common actuation as a multi-way valve «, the also connected in pairs to a single valve group and to a single druok consumer can act.

Sound of the left same of the measuring element 9 then prevails - ■ A lower pressure via the measuring line 8 than on the an- -> whose side of the measuring element, because the smaller inlet '· ■' Opening 7 of valve 1 in measuring line 8 as before the full control pressure comes into effect. The peeling The values 11 are then set in G-ang by shifting the measuring element 9

If one of the switching valves is faulty or not switched jointly in good time, or if, for example, the triggering part for this switching valve, e.g. the switching magnet, fails and the lock in question remains in its lower position while the other is opened, then the safety control also comes into operation and the switch-off means 11 are pressed, because adjusting also here at the valve opening in the measuring tube 8, a pressure reduction and the measuring line existing in the other full control pressure remains.

Ha this pressure build-up and reduction directly in the area the closed position of the closure piece 4 with greater security to determine, is preferably on the locking piece a piston-colored guide 13 is provided, which ia the inlet ■ y, uersci3iiitt with the help of a seal can be adjustable in the axial direction «^ ■ ■ -

The measuring element in this. Embodiment also exists the end. a double piston 9, but with the heating lines 8 preferably over this double piston with the help of an adjustable Throttle point 13 are interconnected, whose Cross-section must be kept much smaller, as is the entire cross-section of the openings 7. In this way it possible, preferably by setting this bridging the auxiliary measuring lines 8 directly on the measuring elements or an αβω ßiojsgiiöa 9> certain movement tolerances as a result of switching inertia of one valve compared to the one to compensate for others or the like, or even to introduce them without the disconnection means 11 responding.

Should also the upper opening position in such a case Multi-way valve for the "b.etref f end closing piece 4 monitored then the valve seat in question also receives 4 ' a similarly designed channel system with a smaller connection at the inlet, which is then also via auxiliary hot pipes, which are not shown in more detail on a further measuring element is brought to inspection "

However, it is also conceivable to bring this channel system into its further valve seat 4>' ^f to act on the already existing measuring element 9, provided that between the two auxiliary measuring lines there are corresponding valves, ζ «Β« in the form of! Check valves are provided which, if necessary, can still be actuated before the movement of the locking pieces 4 or by the valve rods of the locking pieces in a certain stop rhythm as soon as the locking pieces aE leave their central position. It would be conceivable, starting from the middle position of the valve, to switch the auxiliary measuring lines from one measuring point to the other. In this orphan ea is also in multipath - * "r" ntilen possible to monitor both positions of the stoppers. .
