Smith Flow Control (SFC) has introduced its ISO-pattern IML intermediate lock with universal mounting. The IML lock uses an operating key to lock the actuator in an open or closed position so that the valve cannot turn — no matter what. No custom brackets are required; any valve or actuator with ISO standard mountings is compatible with the IML lock. In normal operations, actuated valves respond to process commands in a pre-determined way. But during maintenance, the command architecture may need to be stopped. Ensuring that the valves are set in their failsafe position enables work to be done safely. The IML intermediate lock is available as a key-operated system from the control room or as a standalone lock-out system. Lock Boxes are available with base tags that match up to each lock-out key for ease of identification.
