Quench Valve Product Information - 1

PRODUCT INFORMATION Explosion Isolation EXKOP® QV II + QV III QUENCH VALVES FOR SPACE-SAVING BI-DIRECTIONAL ISOLATION I Made ■ in I Germany Your 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. EXKOP® QV II and QV III are part of the EXKOP® system and comprise a controller and one or several quench valves. 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. Additional functions: • Spark arrester (e.g. between a mill and the product filter) • Overpressure limiter (e.g. between a silo vehicle and the silo)
