Gas Regulators
The GasBoat brand of marine gas regulators are certified to
the EN 12864:2001 standard including Annex M for gas
supply to appliances in seawater boats. The GasBOAT
regulators are equipped with an integral pressure relief valve
and vent as part of the design, there by doing away with the
need for separate parts in an area where spaces is a
premium. They are constructed using suitably corrosion
resistant materials for the marine environment giving them
a working life far in excess of standard camping and
caravanning gas regulators.
IT IS OUR INTERPRETATION OF THE STANDARDS
THAT ANY SALTWATER VESSEL WITH A GAS
SYSTEM THAT IS NOT FITTED WITH AN EN 12864
M APPROVED GAS REGULATOR IS NOT
COMPLIANT WITH BS EN ISO 10239 AND THEREFORE
THE VESSELS INSURANCE COULD BE INVALID!
Why GasBOAT Regulators - The Technical Bit
Since 2001 all marine gas systems should be fitted with a
regular that meets EN12864 Annex M. This means that all
LPG regulators used in the marine market MUST incorporate
either an over pressure shut off valve (OPSO) or over pressure
relief valve. OPSO valves have proven to have too many
moving parts to be reliable in a marine environment. Due to
heel and movement on a boat, the naturally accruing
presence of small amounts of high pressure gas entering the
low pressure side of the system is increased, this high
pressure removed the grease from the valves and safety
cocks, causing them to leak and seize.
Why over-pressure devices?
•
Gas cylinders can be pressurised up to 7 bar
•
Gas cookers have an operating pressure of 30 mbar
•
Appliance control valves only certified to 150 mbar
If the diaphragm fails or the internal lock-up valve does not
close due to seizure, full cylinder pressure can enter the low
pressure side, resulting in a very dangerous leak at the
appliance, the appliance will then need to be repaired by a
skilled engineer before it is safe to use again.
This can also happen if a liquid LPG exits the cylinder, again
due to heel or violent movement of the boat.
EN 12864 annex M:
This standard is for the design and manufacture of regulators
for LPG cylinders to supply appliances installed
in salt-water boats.
Main points:
•
Material in contact with the atmosphere shall be
suitably corrosion resistant. In particular this includes
internal components above the diaphragm
•
The vent shall be on the edge of the diaphragm, in a
suitable location and of suitable size to drain water
which may collect in the diaphragm
•
It shall incorporate an over-pressure relief device, the
vent shall be provided with a pipe connection facing
downwards
•
Operating pressure specification to annex D
•
PD 5482 - 3 2005: Codes of practise for LPG installations
in boats, yachts and other vessels, STATES.
Regulators must conform to EN 12864
•
EN ISO 10239-2000: Small craft LPG installation
regulation covering all vessels built after 15th
November 2000 STATES regulators must incorporate a
pressure reducing device (OVER PRESSURE RELIEF)
•
Be suitably resistant
•
Regulators installed in vessels used in a salt-water
environment must conform to EN 12863 annex M BS
EN16129 was published in August 2013, which
supersedes both.
BS EN16129 was published in August 2013, which supersedes
both EN12864 and EN13786. Annex D of EN16129
refers to caravans, motorcaravans and fresh water boats,
while Annex M refers to sea water boats.
However, the requirements are similar, so we would continue
to recommend that in order to be certain of meeting the
specifications of EN10239 section 5, you should fit a regulator
certified to either EN12864 Annex M or EN16129 Annex M
THE USE OF SUB-STANDARD REGULATORS WOULD
INVALIDATE ANY WARRANTY ON OUR PRODUCTS
