Abstract: In the industry, a way to control fluid pressure circulating through pipes is by means of pilot operated diaphragm pressure controlling valves. This invention specifically relates to pilots of these valves. The pilots of the previous art are mechanical devices comprising diaphragms, springs, throttling elements and slideable shafts. These mechanical devices lose reliability because they get blocked, they deregulate and break; thereby requiring frequent maintenance, and moreover, they do not have the capacity of communication with other control processes. The pilot of the present invention solves these problems because it basically comprises electronic elements which require minimal maintenance and it possesses a capacity to send data signals to other control processes.
