Description
The Dungs VPS 504 S02 leak control unit with a 24 V plug, art: 225481, is used to create a reliable valve check system for the safe operation of industrial gas burning installations. Certified according to European standard EN 1643. Does not require additional adjustments during installation. Designed for gas pipeline pressure up to 500 mbar. The leak tightness of multifunctional solenoid valves is checked by pressurizing the space between the valves. When unacceptable leaks are detected, a lock-out occurs, and the gas supply to the burner stops.
Features and main characteristics:
- power supply from 230 V network, -15%, +10%, 60 Hz;
- control volume for pumping into the space between the valves: from 0.1 to 4 l;
- leak tightness check duration: from 10 to 26 seconds;
- for testing solenoid shut-off valves of class A and B according to EN 161;
- lamp indicating valve tightness/leakage;
- dust and moisture protection level of components class IP 40;
- maximum pressure in the gas supply line 500 mbar;
- permissible temperature range (ambient): -15...+70 °C;
- compact housing made of impact-resistant material;
- built-in replaceable fuse in the housing to protect against short circuits;
- installation position – vertical, horizontal, except inverted;
- mounting to the valve body on 4 screws;
- connection using a plug connection, CSA.
You can buy the leak control unit separately or with additional components (upon request).
Working environment
The valve leak control system is used for installations operating with gases of families 1-3, gas obtained from wastewater treatment, organic waste processing and biogas (dry, H2S< 0.1% volume). It is prohibited to use for gas containing more than 60% butane.
Application
The VPS leak control unit checks the condition of DMV solenoid valves, Dungs universal gas blocks. Leak testing is performed before the burner starts, during pre-purging, or after the heat supply is completed.
