Common features to all regulators, 4005, 4006, 4007 & 4008

Fully certified to EN 12864 annex M (marine environment) Fitted with 75 mbar over-pressure relief valve Vent orifice with 1/8 BSP thread with downward facing nozzle Vent orifice with anti-moisture and contaminant screen Re-enforced diaphragm Marine grade materials

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 Techinical 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, motor caravans 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 PLUS COULD INVALIDATE THE VESSELS INSURANCE COVER!
