Industrial Control Valve Positioners

[Shawn Braquet]

Our site is looking at what else is out there besides the Fisher DVC 6200. We are not having good luck with these. I am in the process of arranging multiple lunch and learns for different manufacturers currently and was curious about what other plants/oil field are using on their control valves. We use mainly Fisher control valves and also have positioners on some the 1/4 turn and 3 way valves with Kinetrol actuators on these valves. 90% of our Fishers are linear valves with the remaining being rotary. The problem that we don't like is going from an older DVC to the 6200 our guys are having problems picking and mounting the adapter kits. I've personally looked at the Masoneilan SVI postioners and like the ease of mounting and set up and the pushbuttons on it are a plus vs carrying a 475 comunicator. I've also heard good things about an Automax positioner. What's the SC's thoughts?
