Why use a medium-pressure-distribution rail?

When cleaning and disinfecting lung-governed demand valves (LGDV) with fluids, there is a risk that fluid gets into the LGDV system, which must not happen under any circumstances. Therefore, it is essential to apply medium pressure to LGDVs during cleaning and disinfection. MENZL medium-pressure-distribution rails are the perfect choice when it comes to preventing fluid from getting into the LGDV system.

How MENZL medium-pressure-distribution rails work

MENZL medium-pressure-distribution rails are intended for installation in places where lung-governed demand valves get cleaned and disinfected. After applying medium pressure to the rail, the LGDVs to be serviced are connected to the rail’s couplings and pressurised by opening the slide valve. Once the LGDVs have been cleaned and disinfected, the self-venting slide valve is closed again and the lung-governed demand valves can easily be uncoupled.

Coupling close-up
Each rail comes equipped with a pressure gauge. When the slide valve is open, the gauge shows the supply line pressure.


In order to ensure the functional safety of the coupled LGDVs, only air of the quality prescribed for SCBAs should be applied to MENZL medium-pressure-distribution rails.

Pressure gauge


MENZL medium-pressure-distribution rails come standard with 3, 6, or 9 couplings. If you need rails with fewer or more couplings, please do not hesitate to contact us.
