VPS 504
Valve proving system for automatic shutoff valves as per EN 161, Class A and Class B
The VPS 504 may be used with any other valve whose tightness in counter-flow direction
excludes by construction a leakage in flow direction.
The VPS 504 is suitable for all DUNGS valves according to EN 161 Classes A and B.

Approx. 10 - 26 s, depending on test volume and input pressure
max. 50 l/h
At inlet pressures of < 50 mbar, limit pressure rates well below 50 l of air per
hour occur due to the mode of operation. This allows for applications involving
low inlet pressures.
