PRODUCT INFORMATION Explosion Isolation QUENCH VALVE QV II + QV III QUENCH VALVES FOR SPACE-SAVING BI-DIRECTIONAL ISOLATION GBPI-QVII_III-15107/5 | © REMBE | All rights reserved | Valid from 06.11.2019 | Subject to technical change without notice Quench valves QV II and QV III are isolation devices. This protective system prevents an explosion pressure wave and flame propagating via connecting pipes into other equipment sections or plant areas. For this reason the quench valve is connected to a controller (EXKOP® Express or EXKOP® TriCon)*. 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. Your advantages •C ompact 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. *Detailled information concerning controllers can be found in the related product information. Additional functions: • Spark arrester (e.g. between a mill and the product filter) • Overpressure limiter (e.g. between a silo vehicle and the silo) Technical data* Diameter nominal** Housing material Certified in accordance with Medium KSt Operating limits ATEX EC type examination certificate no.
