GCE HIGH PRESSURE CYLINDER VALVES FOR TECHNICAL GASES
INFORMATION SHEET (OWNER / INSTALLER)
This information sheet covers essential information for fitting, guarding, filling and maintenance of GCE High Pressure Cylinder
Valves for technical gases.
1. FOREWORD
The product complies with essential requirements of 2010/35/E Transportable Pressure Equipment Directive.
The product with V-9 marking complies with requirements of CGA V-9 standard.
2. INTENDED FOR USE
Cylinder valves for technical gases are used for pressure cylinders, designed for compressed or condensed gases or for gases
dissolved under high pressure. Cylinder valves control gas flow to cylinder during filling and from cylinder during gas usage. Cylinder
valves are designed for gas cylinders with working pressure up to 300 bars. Cylinder valves for N2O, CO2 and CGA V-9 valves are
usually equipped with a safety device which prevents the rise of pressure in the cylinder. Cylinder valves may be equipped with
Residual Pressure Device (RPD) in accordance with EN ISO 15996 that keep the residual pressure in the cylinder. Such cylinder
valves have an extended maximal lifetime to 15 years - see the Lifetime chapter.
3. FITTING
•
This product is supplied in various versions for use with different gases and different cylinder neck threads. Before fitting the
valve to a cylinder, check the information on the valve packaging to ensure you have the correct gas version and stem thread
compatible with the cylinder to be fitted.
•
Valves must be fitted to cylinders according to the requirements of EN ISO 13341. Particular care should be taken to ensure the
thread sealant material is applied correctly and is compatible with the gas service and pressure.
•
Valves must be fitted to cylinders equipped with valve protection device.
•
Use a suitable valve tool for valve assembling. Valving square is located above inlet connection.
•
To assembly, please follow the tightening torques given by EN ISO 13341 standards or recommended by the supplier of cylinders.
•
Maintain oxygen cleanness standards during fitting.
4. GUARDING
•
Valve guarding shall be provided according to ISO 11117.
•
If the cylinder with the valve is not in use (no pressure device connected), the outlet thread should be fitted with a cap or plug.
5. FILLING
•
The product is supplied in various versions of connection standards. Check the connection standard in information on the valve
packaging or on body of the cylinder valve.
•
If the valves are equipped with Residual Pressure Device (RPD), only filling adapters specified by valve producer shall be used.
Caution: Be aware that residual pressure is still present.
•
During filling the ON / OFF handwheel / spindle key must be fully open. Note: Open anticlockwise, close clockwise.
•
After filling do not use an excessive force to close the valve (the torque must not exceed 7 Nm for Ø 65mm handwheel,
resp. 4.5 Nm for Ø 45mm handwheel or 2.9 Nm for Ø 27mm handwheel).
Use only the correct spindle key on key operated valves.
•
After first filling check cylinder / valve joint for leaks. For oxygen and air equipment use only leak detection fluids approved for
use with oxygen systems.
•
Warning: Do not use leak detection or cleaning fluids containing ammonia or other substances, that can cause stress corrosion
cracking in brass materials.
6. MAINTENANCE
•
Repairs can be only done by a GCE certified person who also holds all necessary certificates in compliance with national stand-
ards for mounting and repair of dedicated gas devices. Repair that do not need to be done by a certified personnel include of the
bellow mentioned components: Handwheel, Bursting disc, RPD, protective covers. Caution: Use only original GCE spare parts!
•
Contact your local GCE representative for further details, before returning or removing the product.
7. LIFETIME
Maximum life time of the cylinder valves equipped with the Residual Pressure Device (RPD) is 15 years from the date of manufacture. Lifetime
of all other valves is 10 years from the date of manufacture. All components should be disposed of according to local environmental laws
applicable in the country of disposal. In accordance to Article 33 of REACH GCE, s.r.o. as responsible manufacturer shall inform all customers if
materials containing 0.1% or more of substances included in the list of Substance of Very High Concern (SVHC).
The most commonly used brass alloys used for bodies and other brass components contain 2-3% of lead (Pb), EC no. 231-468-6, CAS no. 7439-
92-1. The lead will not be released to the gas or surrounding environment during normal use. After end of life the product shall be scrapped by
an authorized metal recycler to ensure efficient material handling with minimal impact to environment and health.
To date we have no information that indicates that other materials containing SVHC of concentrations exceeding 0.1% are included in any
GCE product.
