GatEx - Quick-Acting Slide Valve

The GatEx quick-acting slide valve is part of a system used to prevent the propagation of an explosion between the individual units of the production technology. The GatEx is activated when an explosion is detected. The detector sends a signal to the control unit, which activates the closing mechanism. The quick-acting slide valve is closed pneumatically. When an explosion occurs, the pipe will be completely closed in milliseconds. GatEx can be used in facilities using pneumatic conveying, extraction and in places with a short installation distance. It is suitable for technologies designed for maximum explosion pressure (pmax). The design includes fail-safe feature, which puts the slide in a safe state (closed) in case a reliable function cannot be guaranteed. The device is certified according to EN 15089.

WHERE IS THE RISK?

In technologies, due to the ignition of an explosive mixture, such as a mixture of dust with air, gas with air, combustible mist, and their combinations. In pneumatic transport, the risk of explosion is higher because the initiation source can enter the piping system very easily at the beginning of the entire process.
