Neles NE700 and NP700 are proportional positioners for control valves. The NP is a fully pneumatic unit, while the NE is an electro-pneumatic unit that provides pneumatic output proportional to a standard milliampere DC input. Both units can be used with either cylinder or diaphragm-type actuators for rotary or linear valves to provide excellent repeatability and accuracy in a wide range of throttling applications.
