Smart valve positioner, dust explosion-proof ExtD, straight stroke, single acting, failsafe, split body anti-high temperature vibration

Reasons for the Use of Smart Positioners

In most respects smart positioners perform the same basic function as the basic analogue positioners combined with current to pneumatic converters. However, the key advantages for using smart positioners are:

· Automatic calibration and configuration. Considerable time savings are realized over traditional zero and spanning.

. Valve diagnostics. Through the Distributed Control System (DCS), PC software tools, or handheld communicators, users can diagnose the health of a control valve while it is in the line.

. Reduced cost of loop commissioning, including installation and calibration.

. Use of diagnostics to maintain loop performance levels.

· Improved process control accuracy that reduces process variability.
