Neles Valmet Mets o NE724/S1 NE Series Electro Pneumatic Valve Positioner

These electro-pneumatic positioners operate on a milliampere signal from a controller. They accurately position the control valve assembly in response to a change in input signal.

This electro pneumatic positioner is proportional positioners for control valves. NE valve positioner is an electro-pneumatic positioner 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.

The nominal input resistance is 190 ohms. The moving force coil assembly has low mass and is accurately balanced to assure proper function even in severely vibrating applications. The dynamic behaviour of the positioner can be changed by choosing different size pilot valves.
