20" high performance butterfly valve with Kinetrol actuator |
Requirement:
It's necessary to prevent a $30M USD axial process air compressor from rapidly going into an overspeed condition that could harm equipment, infrastructure, and personnel.
Challenge:
The biggest challenges: stroking the valve in under one second, but without slamming the butterfly disc into the stops which can damage the valve and nearby equipment.
Solution:
Kinetrol's expertise in rapid cycling enabled us to size, select, and perform certified cycle time tests on the final assembly. This shut out any competition.
Assembly:
20" class 300 high performance butterfly valve, Kinetrol 207-120 with a 2" automatic L-Port, 3-way, compressed air supply ball valve with 097-F120, X-proof solenoid, and two exhaust silencers coupled to the size 20 supply port. Open / closed limit switch assembly. Robust SST mounting bracket and coupling. The closure time once actuator air is exhausted: 0.13 seconds.
