Description

The NP700 pneumatic and NE700 electro pneumatic positioner can be used with either piston or diaphragm actuators for linear or rotary valve service to provide excellent repeatability and accuracy. The series offers rugged construction with few parts and small moving mass and rigid mounting to provide excellent resistance to vibration. Multiple pilot valve sizes are used to match positioner capacity with actuator stroke volume that significantly improves response times, particularly with large control valves.
