EXKOP® QV II
Isolation with quench valves.
The REMBE® EXKOP® QV II quench valve is an isolation device that is installed in a pipeline to prevent explosions from propagating to other parts of the processing system. To do this, the quench valve is connected to a controller (EXKOP® Express or EXKOP® TriCon).
bidirectional
isolation.
Application
REMBE® EXKOP® QV II is compatible with a Spark arrester (e.g. between a mill and the product filter) and an overpressure limiter (e.g. between a silo vehicle and the silo).
Mechanism
In the event of an explosion, the 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 quench valves. These close within a few milliseconds and thus prevent the explosion from spreading to adjacent plant components. After being triggered, the quench valves can be put back in operation once again at the touch of a button.

EXKOP® QV II
- Compact design for flexible integration into the production process.
- High level of safety due to very rapid closing times.
- Returns to operation immediately after triggering.
- Fail Safe mechanism automatically closes the valve if the power supply fails or the valve is manipulated.
