Safe cleaning of Pipelines with Pig Scrapers and Valve Interlock Systems

www.Haake-Technik.com, Germany, presents in this video demonstration on its valve interlock systems how pig scrapers are inserted into the pipeline system of the pig launcher and valve interlocking system is used to protect the operator, the appliance as well as the environment. The operation of the valve interlocking system is explained in the this animation. An operating error at a valve can have dramatic consequences -- personal injuries, damages to the plant, or even contamination of the environment can be a result. Thus, the safe operation of valves must be guaranteed. By using the Haake Safety Valve interlocks you can be sure the correct sequence of operating procedures will always be adhered to. Keys are inserted into the Sequence Control Unit (SCU). This system also guarantees that no unauthorized opening of the pig launcher is possible. The mechanical control and interlock system avoids operating errors at valves.
