Electro Pneumatic Positioner Model NE700

NE positioners
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.
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.
FEATURES
Excellent vibration resistance
Rugged construction, few parts, small moving mass, compact design and rigid mounting provide outstanding vibration resistance.
Field reversible
Positioner can be set for direct or reverse-acting modes by simply turning around the changeover piece and feedback cam without touching or changing tubings between actuator and positioner. Split-range and reverse actions are standard on the feedback cam.
Easy and fast to calibrate
Calibrations can be easily made with the positioner cover removed. You can fine-tune zero and range adjustments with minimal effect on set points.
Fast response times
Multiple pilot valve sizes are used to match positioner capacity compatibility with actuator stroke volume, minimizing response time.
Stable operation
Changes in supply pressure and valve load have minimal effect on positioner operation.
