Description

The VPS 504 is a valve proving system for DMV series automatic 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 VPS will halt the start-up sequence to a burner if it detects an open automatic shutoff valve, thus preventing ignition under potentially dangerous conditions.

Application:
The VPS 504 is recommended for industrial and commercial heating applications.  Various model types are: 504 06: 120 Vac, 504 06: 24 Vdc, 504 04: 110 Vac and 504 04: 230 Vac.
