Pneumatic and Electro Pneumatic Valve Positioner
The Type-2000 Pneumatic and Electro-Pneumatic valve positioners are designed to provide stable and accurate control of rotary and linear valves.
The Type-2000 Pneumatic and Electro-Pneumatic valve positioners are designed to provide stable and accurate control of rotary and linear valves. These force balanced devices are operated with cam characterised air pressure control utilising a low friction spool valve to accurately drive rotary and linear pneumatic actuators. The force balanced instruments are simple, reliable and user friendly for calibration, maintenance and field upgrades.
The Electro-pneumatic unit is available with worldwide safety approvals in an Intrinsically safe and Explosion-proof version. The IP 66 housing provides rugged resistance to severe industrial environments. The modular design of the Type-2000 allows multiple feature ordering options or easy field conversions.
