Isolation with quench valves: EXKOP® SYSTEM

Space-saving, bidirectional isolation


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.

The EXKOP® system is ideal in combination with explosion vents or flameless explosion venting solutions.

Your advantages

  • Effective protection through high-speed detection of explosion events.
  • Returns to operation again immediately after triggering.
  • Self-monitoring safety electronics with operating data storage.
  • Modem-compatible remote system analysis permits remote maintenance.
  • System status or error messages reported immediately via the operating and touch panel.
  • Processes wide range of trigger signals for easy retrofitting to existing plants.
  • Fail Safe mechanism automatically closes the valve if the power supply fails or the valve is manipulated.
