Are “pneumatic” and “electropneumatic” the same thing or different?
In reference to MDC valves, both terms mean the same thing: pneumatic is simply a shortened version of electropneumatic. Pneumatic refers to the use of air pressure to operate a valve. The “electro” portion of electropneumatic means that electricity is used to direct the air pressure to make the valve either open or close. None of the MDC valves are operated entirely by electricity. All electropneumatic valves require both electrical and air service to operate.
