Description
The DUNGS VDK 200A is a valve proving system for safety shutoff valves. It checks that both safety shutoff valves in a gas train are fully closed before a system startup or after system shutdown when wired and interlocked to a suitable flame safeguard control. The VDK 200 will halt the startup sequence to a burner if it detects an open safety shutoff valve, thus preventing ignition under undesirable conditions.

Application
The VDK 200A is recommended for industrial and commercial heating applications. Some authorities having juristiction accept the VDK 200 in lieu of "proof of closure" when integrated with the pre-ignition system. It can also be used in lieu of a vent valve when it checks the valves at start up and shut down. The VDK 200 is suitable for natural gas, propane, butane air and other inert gases. Not suitable for Hydrogen.
