Neles Series NE700/NP700 Proportional Positioner

Brand: Valmet

Metso's 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.
