Frequently Asked Questions
- How does the excess flow valve work? The valve mechanically shuts off the gas flow if it exceeds the set value (e.g. in case of a damaged hose or a leak downstream of the valve), preventing an uncontrolled release of a larger amount of gas.
- What flow values are available? Common sizing is 2.5 m³/h and 4 m³/h, depending on the bore and type of the connected appliance.
- What is the difference between L-MF and L-FM? It is the thread orientation - L-MF has a male thread at the inlet and a female thread at the outlet, L-FM is the opposite; the choice depends on the direction of installation into the existing pipework.
