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
EN
out of service for repair (see Chapter 9).
Note: Colour of the product (especially guard, flow control head and shut-off valve)

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
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 .
The product is only designed for use with gas specified on its marking. Never try to fit
to a gas cylinder specified for different gas type.
If you suspect that inner parts of the combination valve have been contaminated, it
and gas cylinder for contamination. If needed, apply the
