VPS Dungs – valve proving system for multifunctional gas controls These valve proving systems VPS may be used with any other valve whose tightness in counter-flow direction excludes by construction a leakage in flow direction. Equipment operates independent of residual pressure in the range of the permissible operating range.

Tightness or leaks are dungz by a LED.

S044 for TRD systems. Electrical connection possible by plug connection for S01, S02 and S No rewiring is required for contact allocation as per DIN S04 and S05 have an electrical connection at screw terminals fungs PG Suitable for gases of gas families 1, 2, 3 and other neutral gaseous media.

Program sequence Idle state: Valves 1 and 2 are closed. The internal motor pump increases the gas pressure in the test section by approx. During the test period, the installed differential pressure switch monitors the test section for leakage.

If the test pressure is attained, the motor pump is switched off end of test period. The release time s depends on the test volume max 4 l and input pressure max. If the test section is tight, the contact is released to the automatic burner control after max.


The red signal lamp lights as long as the contact release by the regulator of thermostat is present heat requirement.
