The Smith Flow Control ISO-pattern IML intermediate lock with universal mount uses an operating key to lock the actuator in an open or closed position so the valve cannot turn. No custom brackets are required; any valve or actuator with ISO standard mountings is compatible with the lock. Made of 3/16-in. stainless steel for harsh environments, 6 models cover all ISO 5211 patterns. The lock is available as a key-operated system from the control room or a standalone lock-out system.
