STORAGE, TRANSPORT
3.
For storage all parts must be packed in a clean condition, dust-free, dry, and well closed. Use
only appropriate packing material. Do not use cleaning agents which contain solvents!
All components which have been in contact with corrosive or toxic gases must be purged with
an inert gas before sending to the manufacturer.
4. TECHNICAL DATA
4.1. GENERAL DESCRIPTION
The BMD 500-35 battery pressure reducer is a single-stage pressure reducer with automatic
change-over.
The automatic change-over from an empty cylinder to a full one is accomplished by means of
back pressure with no added pressure. The change-over switch lever points to the feed
cylinder.
When used properly this arrangement provides a continuous supply of gas.
An integrated blow-off valve provides safety against high pressure buildup.
Blow-off valve: opening pressure = P4 x 1.3... 1.5.
