EXKOP® System

Space-saving, bidirectional isolation.

Made in Germany
This system isolates plant components 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. As well as operating as a decoupling system for dust-bearing plants, the EXKOP® system can also be used as a spark arrester or overpressure limiter.


Compact central unit for QV II quench valves in fail-safe design.

EXKOP® Express

Control Systemor for all decoupling devices.


for a space-saving, bidirectional decoupling, nominal sizes up to DN 250.
  • 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.
  • Instant recognition of system status in HMI.
  • Instant status forwarding to customer PLC (Alarm, failure, maintenance, etc.).
  • Processes wide range of trigger signals for easy retrofitting to existing plants.
  • Fail Safe mechanism automatically closes the valve if the power / compressed air fails or the valve is manipulated.
  • Reliable, process-optimised protection against explosions in adjacent plant components.
  • Avoid downtime after the mechanism is triggered.
In the event of an explosion, the EXKOP® controller receives a trigger signal (e.g. from the signalling unit of the Q-Rohr® or an explosion vent, from a pressure switch or spark detector) and activates the connected EXKOP® quench valves. These 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.

  • Unboxed - EXKOP® Maintenance

    REMBE is your specialist in the field of explosion safety and pressure relief and offers holistic safety concepts for plants of all kinds in a wide range of industries. All products are manufactured in Germany and meet the requirements of national and international regulations. This video explains how the maintenance of a quench valve with connected EXKOP EXPRESS controller is carried out by the service specialists from REMBE Advanced Services + Solutions GmbH. Using a test setup with a Q-Box installed on a filter and a short pipeline, which is decoupled with a quench valve in the event of an explosion, the maintenance is shown realistically. The maintenance of the EXKOP system may only be carried out by the REMBE Advanced Services + Solutions GmbH team as a qualified person.
