Description

The VDK is a valve proving system for safety shutoff valves. It verifies that both safety shutoff valves in a gas train are fully closed before a system start-up or after system shutdown when wired and interlocked to a suitable flame safeguard control. The VDK will halt the start-up sequence and prevent ignition when the VDK detects an open automatic shutoff valve or valve leakage exceeding the detection limit.

Application:
The VDK is recommended for industrial and commercial heating applications.
