EXKOP® System
This system isolates plant components in both directions and consists of a self-monitoring EXKOP® controller with data storage and one or several quench valves.
bidirectional
isolation.
Application
In the event of an explosion, the EXKOP® controller receives a trigger signal (e.g. from the signaling unit of the Q-Rohr® or an explosion vent, from a pressure switch or spark detector) and activates the connected EXKOP® quench valves. The quench valves close within a few milliseconds and thus protect interconnected plant components. After being triggered, the quench valves can be put back in operation once again at the touch of a button.

Compact central unit for QV II quench valves in fail-safe design.
for a space-saving, bidirectional decoupling, nominal sizes up to DN 250.
Control Systemor for all decoupling devices.
- 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-optimized protection against explosions in adjacent plant components.
- Minimal downtime after the mechanism is triggered.
