for a space-saving, bidirectional decoupling, nominal sizes up to DN 300-600.

Made in Germany

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).
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).

  • 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.
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.

  • 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.
