Electronically controlled pneumatic transducer, shutting electronically controlled pneumatic transducer and electronically controlled pneumatic ooff valve

The utility model provides an electronically controlled pneumatic transducer, shutting electronically controlled pneumatic transducer and electronically controlled pneumatic ooff valve. The transducerthat has lower part shells assembly and upper portion shells assembly is used for being connected to the fluid pressure source, and this fluid pressure source has the mechanism that is used for setting up pneumatic output via electric incoming signal. Lower part shells assembly should supply the nozzle and pass through internal fluid channel and supply end mouth fluid intercommunication includingbeing configured as the lower part casing of acceptting the supply nozzle to output port intermittent type fluid intercommunication with the lower part casing. The lower part casing further includesdischarge nozzle, this discharge nozzle and discharge port fluid intercommunication to through the output port intermittent type fluid intercommunication of internal fluid channel with the lower partcasing. Upper portion shells
