PMV-D30 Intelligent Valve Positioner

SA Instrumentation & Control Magazine – Front Cover Jan 2021.

While pumps and valves frequently get most of the attention, it is often the actuators and positioning solutions that are running the show.

Over the last few decades, the process plant instrument technician’s day in the plant has become busier. They see an increased work load in combination with increased pressure for plant uptime and reduced maintenance cost.

Their knowledge base must today span from mechanics to pneumatics, and hydraulics to data communication, i.e., system level interaction. They get less time to learn how to handle new instruments and to read IOM manuals. Knowledge on how to handle older design process instrumentation, based on springs, bellows, cams and manual calibration, is getting lost. With this in mind, PMV designed a simple to use yet very advanced modular digital positioner, which can be used on rotary or linear actuators, both single and double acting.

NAF D30 Valve Positioner – No Brackets or SS Piping Required

The NAF-D30 is an intelligent valve positioner designed to operate pneumatic rotary valve actuators from control systems and electrical controllers with the analog control signal 4-20 mA, optionally superimposed by the HART communication signal. It forms an integrated part in the NAF-TorexNAF-Setball and NAF-Duball control valve package with a unique direct mounting and does not require brackets. The air block between positioner and actuator means you no longer need to find SS fittings and bend SS tubing.
