Comprehensive interlocking for the power industry

Massillon, Ohio — Kirk Key Interlock Co. will exhibit its full range of mechanical, electromechanical, transfer, access, and bolt trapped key interlocks, including the new Eagle Series for valve interlocking, at the 2014 Air Pollution Control/Pollution Control Users Group (APC/PCUG) Conference Expo July 14-15, at the Galt House (Louisville, Ky.), booth 79.

Kirk's interlock systems protect personnel and equipment by ensuring a pre-determined safety sequence is followed each time hazardous equipment is accessed in the power industry. Its new Eagle Series integral valve interlocks fit nearly every type and size of quarter and multi-turn valves. The Heavy Duty (HD) Series trapped key interlocks are designed for long, reliable service life in challenging environments. The robust construction withstands weather and the high fly ash levels in coal burning power plants. When used in combination, Eagle and HD Series locks provide a comprehensive safety system for the power industry.

Visitors to Kirk's booth will find informative hands-on demonstrations and animations illustrating trapped key interlock coordination schemes specific to the power industry.
