Safety regulator/R

Regulators perform the task of keeping the outlet pressure constant within specified limits, regardless of the fluctuations of the inlet pressure and the changes in the flow rate. The hose rupture safety device provides a flow rate limitation.

Hose rupture protection/S (above ground)

The hose rupture safety device is a safety device which automatically closes the gas outlet if a certain flow rate is exceeded (e.g. in the event of a hose rupture). When operating equipment on construction sites from containers with a volume exceeding 1 I and a hose length exceeding 40 cm, hose rupture safety devices are required above ground level in accordance with the accident prevention regulations. The hose rupture safety device is connected downstream of the regulator.

Safety regulator with integrated hose rupture protection/RS (above ground level)

The hose rupture protection is an integral part of the regulator.
Safety controller with integrated leakage test and hose rupture protection/RDS (below ground level)
In addition to a hose rupture protection, a leakage test is also installed in the controller, with which the entire consumption system is necessarily tested for leakage before startup. The leakage test includes the entire pipe network including the connections on the inlet and outlet side as well as the device valve. This safety function is achieved with commercially available, standardized hoses and connections. The accident prevention regulation (BGV D34) requires regulators with integrated leakage test and hose rupture protection with a nominal value of up to 1.5 kg/h (RDS) or leakage gas safety devices* for connection for liquid gas-operated tools used below ground level, e.g. in cable construction.
*Leakage gas safety devices shut off the gas supply exclusively in the event of hose damage. They function with a special double hose and special connections.
