Very High Cycle, Coal Power Plant Butterfly Valve Application

One moving part. Simply the best.

A coal fired power plant was using old Powell gate valves with dual air cylinders and volume tanks. Because of high cycle rate (the valve cycles open/closed every 30 seconds), the Powell gate valves were breaking down constantly - leaking at first, then failing. Downtime for repair was costing a fortune.

A local Kinetrol Distributor was called in to recommend a better solution. After discussing the capabilities of Kinetrol, the power plant decided to replace the gate valves with 6" high performance butterfly valves actuated with Kinetrol size 12 actuators, spring returns and limit switch packages. 

The result was a robust valve/actuator package that could handle the 120 cycles per hour required - truly a difficult application. As of two years in operation, both valve and actuator have been running reliably much to the delight of the power plant maintenance crew.
