Eagle Series valve interlock systems

Made in America since 1932

Eagle multi-turn (MT) valve interlock are designed to fit any size valve with a rotating stem (gate, globe, or gearbox operated) and are available in single or dual key designs. Since the number of rotations to open/close a valve varies, the multi-turn interlock incorporates a counting mechanism, which is commissioned after installation, to trap and release keys at desired positions. This feature also allows for field adjustment of the key release positions should the valve seat become worn.

Eagle quarter-turn (QT) valve interlocks are designed to fit all types and sizes of quarter-turn valves (ball, butterfly, and plug) and are available in single or dual key designs. The original valve lever is replaced with a KirK® sliding lever interlock mechanism. Versions are available to suit 3-way/180 degree movement valves. The lock assembly can be used with rotary switches for single or dual key operation.

The Eagle Series features a unique, robust, oversized key design with codes that cannot be duplicated. Custom-engraved key tags suit any client/project requirements. Keys are designed for easy mounting in Eagle Eye key cabinets and are coordinated with color-coded key and cabinet tags.

KirK® Eagle valve interlocks are available in both single and dual key versions to fit all sizes and types of multi-turn or quarter-turn valves. Designed to be mounted directly to the valve, the original operating wheel or lever is replaced with a KirK® interlock assembly. There is no dismantling, modification or welding required to install KirK® Eagle valve interlocks, preserving the certified pressure envelope of the valve, maintaining any valve manufacturer’s warranties. KirK® Eagle interlocks can be installed during live process operations without shutting down a system. KirK® Eagle interlock systems ensure a safe, predetermined sequence of operations is always followed.
