The Dungs VPS 504 S02 is a valve leak detection system in the Dungs VPS valve-proving programme. The Dungs VPS 504 S02 is a valve-proving system that automatically checks the gas train for leaks before every ignition, a standard safety layer on larger trains. It is brand dealer (ali-verified), cross-checked against the original before supply.
Overview
Dungs VPS 504 S02 Valve Leak Detection System at a glance
The Dungs VPS 504 S02 runs an automatic valve-leak-proving cycle on the gas train before every ignition, blocking light-off if either seat of a double valve leaks. On larger industrial trains where codes demand proved safety, it sits between the gas valves and the burner control and reports a relay signal the controller trusts. The ~30-second proving window is short enough not to annoy operators yet long enough to catch a weeping seat. It is the standard Dungs safety layer for double-valve trains and we wire it to match the existing control box.
