Dual control system valve.

A DEVICE FOR CONTROL AND MONITORING OF TWO fluid valve in which each fluid valve comprises means DRAG adapted for activation by a control signal associate and a valve MOBILE is directed toward a first position WHICH TO PREVENT fluid flow through the valve, and can be driven by the drive means to a second position in which fluid is able to flow through the valve, a first switch THAT CAN BE POWERED BY SLIDING ELEMENT first valve, a second switch that can be actuated by the moving element of the second valve, each switch is directed toward a first position and each switch can be dragged to a second position when the SLIDING of the associated valve assumes its second position . According to this invention, BOTH SWITCHES (20, 21) are adapted to INFLUENCE THE PATHS OF CONTROL SIGNALS IN TWO POSITIONS OF SWITCHES AND ARE CONNECTED IN A MANNER THAT PREVENTS implementation of the first control signal (S1) A DIRECTLY The first valve (20) with the first valve in its first position when TAKES PLACE THE APPLICATION OF THE first control signal (S1) after the elapse of a predetermined time period from the time of activation of the second valve and TO AVOID THE APPLICATION OF THE SECOND control signal (S1) to the second valve when in its first position IF yOU HAVE PLACE implementation of the second control signal (S2) after it has elapsed predetermined time period AFTER aCTIVATION the first valve. Both switches (20, 21) are connected in a way that allows each control signal is applied to an entraining RESPECTIVE SIMULTANEOUSLY WHEN DEALING two switches its second position.
