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.
