This AR ceramic valve series is designed for outstanding control precision, repeatability, resolution, and other characteristics needed for high-speed operation in a compact body — qualities unachievable with conventional motor drive valves.

• Electronic signal. Operation with a4-20 mA instrumentation signal.
• Outstanding resolution. Standard models take 2133 steps per full stroke. 
• Less than 0.1% hysteresis.  AR2000 electronic valves use a stepping motor for extremely high stroke positioning. 
• Direct computer control.  Simply install an interface to enable direct computer control.
• No electro-pneumatic converter required. Valves can be controlled by cable up to 100 m from the control panel.
• Explosion-proof designs (d2G4) available.
