Safeguard loading and unloading of pipeline inspection gauge launchers and receivers with a full line of key interlocks.
These single or dual-keyed mechanical locking devices control the sequence in which process equipment may be operated. Using a ‘key transfer’ principle, operational control over safety-critical processes is said to be assured. The interlocks comprise stainless steel. They are lubricated for life. Each quickly installs on any standard size valve or associated equipment — without modifications. Complete interlocks data are free.
