Interlock Technology Improves Process Safety in Tanker Loading/Unloading Operations

image009Kirk Key’s (Kirk) Eagle Series interlocking products provide process-safety control in tanker loading and unloading operations. The company’s trapped key interlocking systems ensure that users follow a pre-determined sequence of operation for activating road, rail, and sea tanker control valves in oil refining, petro-chemical, pulp and paper, liquefied gas and other industrial applications. Kirk Eagle Series valve interlocks integrate with its mechanical and electromechanical trapped key interlock series to form a comprehensive safety scheme.

According to the manufacturer, product-transfer procedures that rely on manual control can lead to spills or leakage of hazardous gases or liquids, causing injury, property damage and potential fines. By controlling a defined sequence of equipment operation, such hazards are minimized.

The company says its interlocking systems are designed to site requirements and ensure that safety processes move smoothly across a range of equipment including road, rail or marine barriers, hoses, gantry accesses, valves and pump electrical switches. Each step in the scheme releases a uniquely coded key required to move safely on to the next step of the sequence. These oversized keys can’t be duplicated and the sequence can’t 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. To support long-term use in harsh environments, all Eagle Series products are manufactured entirely of 316 stainless steel and incorporate keyways that are protected by a gasketed flip covers.
