Specifications:

Valve proving system for DUNGS single valves, DMV double solenoid valve and GasMultiBloc MB. The VPS 504 can also be used for monitoring the DUNGS solenoid valves up to DN 80, with and without bypass connection. 24 VDC design for gas motors. Suitable for gases of gas families 1, 2, 3 and other neutral gaseous media.

• The VPS 504 230V is a valve proving system for DMV and MB 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.
