North Canton, Ohio – KIRK® Eagle series valve interlocking products provide process safety control in hydrogen cooled generator purging operations. The company’s Eagle series trapped key valve interlocking systems ensure that users follow a pre-determined sequence of operation for startup and maintenance on generators in power stations, refineries, chemical plants, and other industrial applications. KIRK Eagle series valve interlocks integrate with its mechanical and electromechanical trapped key interlock series to form a comprehensive process safety scheme.

Purging generator rotating systems with hydrogen reduces drag and windage loss in the system. Improperly introducing air into the generator on startup, without first purging it with carbon dioxide or hydrogen, can create an explosion hazard. By controlling a defined sequence of gas valve operation, proper purging procedures are enforced and hazards minimized.

Interlocking systems are designed to site requirements and are fitted to the gas control valves. The KIRK sequence control unit then regulates the release of the uniquely coded keys required to move safely through the steps of the sequence. The robust oversized keys cannot be duplicated and the sequence cannot be circumvented.

The Eagle series includes integral valve interlocks to fit every type and size of quarter and multi-turn valves, as well as bolt and electro-mechanical interlocks. For long-term use in harsh environments, all Eagle series product offerings are manufactured entirely of 316 stainless steel with keyways protected by a gasketed flip cover.
