We came up with 10 Reasons to Install a Valve Positioner so you can discover ways that a positioner could improve your control process. Here is a quick summary of reasons to use a valve positioner on your rotary or linear control valves:
Ability to have fine control over a precise process.
Increase the speed of response to change in process, allowing for faster loading and venting.
Allow for split ranging (one controller for two valves).
Overcome seating friction in rotary valves.
Allow for increased usage of 4 – 20mA electronic signal.
Minimize valve stem packing friction effects and the resulting hysteresis. This is particularly important for high temperature packing materials like graphite.
Negate flow-induced reactions to higher pressure drops and compensates for internal force imbalances.
Allow the use of characteristic cams in rotary valves.
