Technical Information

TECHNICAL GAS, BURNING GAS & VACUUM VALVES

SPECIFICATION

Materials
Brass DIN 17660 and nickel with Viton sealing & PDVF. High flow headworks have SS 2343.

The 4.0 grade Oxygen valves are specially cleaned and have O2 lubricant.

Handels are moulded in chemical resistant polypropylene coloured to match the service medium in accordance with EN 13792:2002

Outlets
Serrated nozzles suitable for 8mm to 13mm bore rubber tubing, and if the nozzle is removed a 3/8" female connection is available. (See the range of nipples and sockets in the section with accessories)

Important Note
Oxygen service valves are specially cleaned, lubricated and packed. USE ONLY SPECIFICALLY CONSTRUCTED FITTINGS FOR OXYGEN.

Max Pressure & Testing
All fittings are leak tested before leaving the factory.
For maximum pressure levels see specifications on page 4-6.

Purging of new installations with compressed air or nitrogen is recommended to clean the system.

Medical Gas Cleanness for Oxygen Fittings
Oxygen (or other grade 4.0 clean technical gases) lines require purging with grade 4.0 Nitrogen in order to avoid contamination.

Hazardous or aggressive gases (ie. ammonia) may require special fittings. For advice please consult us.

The gas supply should be clean, and free of contamination. Vacuum taps can be fitted with flow restrictors to help balance the system.

Supply pressure for gases should be reduced to at least 1.4 Bar from the supply cylinder, for safety reasons (ref BS3202: 1959" recommendations on Laboratory furniture and fittings").
