J - EXCESS FLOW DEVICE OR DIP TUBE (OPTION)
Excess flow device ensures safe ventilation of gas from gas cylinder in case the combination
valve is broken above inlet stem (e.g. cylinder fall). Dip tube does not have such function. Excess
flow device and dip tube are to avoid contamination from cylinder entering the combination
valve .
PRESSURE RELIEVE DEVICE OF HIGH PRESSURE PART - BURSTING DISC (OPTIONAL)
The high pressure relieve device is intended to protect the cylinder and high pressure part
of combination valve against damage caused by increased cylinder pressure. If the pressure
relieve device has been activated, it will not reseal and the combination valve must be taken
out of service for repair (see Chapter 9).
Note: Colour of the product (especially guard, flow control head and shut-off valve) does not
have to match the gas colour coding.

6. USE OF PRODUCT

6.1. OPERATIONS PERFORMED BY THE PROVIDER, DISTRIBUTOR -
FILLING STATION
6.1.1. GUARD
A valve guard should be provided where possible. If the used guard comply with EN ISO 11117
standard the package of combination valve with guard and gas cylinder must meet the drop
test requirements according to EN ISO 10524-3.
The total weight of the package as marked on the combination valve must not be exceeded if
the GCE guard is used, the guard does not comply to EN ISO 11117 or no guard is used.
Note: Total weight of package includes weight of combination valve , weight of cylinder filled
with gas to max. limit and all permanently fixed parts.
The guard must allow easy access to all controlling elements of the combination valve , must
not inhibit connection of medical devices and other accessories to the combination valve outlet
(ex. filling adaptor), must not influence any functions of combination valve (ex. pressure relieve
valve) and inhibit legibility of labels and marking.
There is a higher risk of damage if the combination valve is used without a guard.
6.1.2. FITTING THE COMBINATION VALVE TO A GAS CYLINDER
Observe oxygen cleanliness standards during installation.
Check combination valve and gas cylinder for visible damage (especially inlet stem thread of
•
the combination valve and thread of gas cylinder).
Check combination valve and gas cylinder for contamination. If needed, apply the cleaning
•
procedure according to chapter 8. For gas cylinder cleaning, refer to the cylinder manufacturer
cleaning procedure.
Check if the total life time of the combination valve and the gas cylinder has not been
•
exceeded.
• Ensure that the product inlet stem is compatible with the gas cylinder.
Check the presence & the integrity of seals / sealing materials (PTFE tape, O-ring) on inlet
•
stem.
• Check that the gas cylinder pressure rating is higher than inlet pressure of the combination
valve .
• At variant with GCE guard take off the filling port protective cover.
• Ensure that fitting equipment does not interfere with/or damage the guard and other parts of
the combination valve or cylinder.
• Assembly combination valve on gas cylinder To tighten the combination valve in cylinder use
only the square surfaces of the combination valve body. The across flat size of square surface
is 26 mm. During fitting of combination valve to the cylinder follow torque figures specified
in EN ISO 13341.
Return filling port protective cover on the combination valve.
