Pneumatic and Electro-Pneumatic Valve Positioner

Stable and accurate positioning 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 characterized air pressure control utilizing 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 NEMA-4X (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.
