This system isolates plant equipments in both directions and comprises a self-monitoring EXKOP® controller with data storage and one or several quench valves.
EXKOP® systems are suitable for filling lines, aspiration lines and pipes, pneumatic conveyor lines and air intake openings. In addition to operating as a decoupling system for dust-bearing plants, the EXKOP® system can also be used as a spark arrester or overpressure limiter.
In the event of an explosion, the EXKOP® controller receives a trigger signal (e.g. from a Q-Rohr® or explosion vent signaling unit or from a pressure switch or spark detector) and activates the connected EXKOP® quench valves. These quench valves close within a few milliseconds and thus protect adjacent plant components. After being triggered, the quench valves can be put back in operation once again at the touch of a button.
