Explosion isolation system EXKOP® QV III

Decoupling with quench valves. The REMBE® EXKOP® QV III quench valve is a decoupling device that is installed in a pipeline in order to limit any explosions to the relevant part of the system. To do this, the quench valve is connected to a controller (EXKOP® Express or EXKOP® TriCon). Application REMBE® EXKOP® QV III is suited 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) Advantages 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. Mechanism In the case of an explosion, the 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 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.
