Solenoid Valves for Bio Fuels

B100 (100% pure bio-diesel)

B100 bio-diesel or FAME are not compatible with many hoses, seals, gaskets, seals, glues and plastics and will attack NBR Nitrile rubber elastomers, polypropylene and polyvinyl.

PTFE (Teflon), FKM (Viton), Nylon, fluorinated polyethylene, fluorinated polypropylene and most fibreglass’s offer excellent resistance to bio diesel and FAME B100.

This can cause major problems for users with older engines with incompatible component parts. Engines lose about 12% power and 18% fuel economy with B100 biodiesels. Bio-diesel can reduce water separator efficiency and cause cold weather flow degradation if no fuel conditioner is added. Storage tanks should be kept as full as possible to reduce condensation and microbiological growth. Bio-diesel tends to increased NOx emissions whilst reducing smoke.

FAME (Fatty Acid Methyl Esters)

Fame are esters of fatty acids which have similar characteristic’s of fossil diesel fuels than vegetable oils, but those properties depend on the type of vegetable oil used during the manufacturing process. Fame is non toxic and biodegradable.

EC Funded projects on Fame.

SUPER METHANOL – Reforming of crude glygerine in super critical water to produce methanol for reuse in bio-diesel plants.

InteSusAl – Demonstration of integrated & sustainable enclosed raceway and photobioreactor microalgae cultivation with bio-diesel production and validation.

ALLGas – Industrial scale demonstration of sustainable Algae cultures for biofuel production (Bio-diesel and Biogas).

BioFAT – Microalgae to bio-fuel demonstration.


Tests my motor manufacturers in the EU on blended with diesel ranging from 5 to 10%, 25 to 30% and 100% pure have resulted in guarantee’s for each type of use.

Modifications to seals and pipework are required for use with B100 100% pure FAME and biodiesel. The use of biodiesel or FAME as a low blend component in transport fuel up to 7% B007 in the European Community according to EN590, do not require changes to sealing or pipework.

Suitable metals for use with Bio-diesel and FAME include

Aluminium, steel and stainless steels. Bio-diesel will oxidise generating insoluble such as gels and salts if in contact with red metals such as brass, bronze, copper, copper pipes, copper fittings, brass regulators, lead, lead solder, tin, tin solder or zinc. Brass, bronze or copper valves and fittings can corrode and become brittle over time and will discolour showing a greenish tint, causing valve failure and leakage. Bio-diesel leach small amounts of copper and zinc into the fuel itself serving to catalyse the degradation of bio-diesel. The corrosive effects are significantly reduced in higher temperatures and absence of oxygen. High temperatures and sunlight increases degradation of bio-diesel fuel. Ambient temperatures and the absence of sunlight are best suited for bio-diesel storage.

B20 (20% blended bio-diesel)

B20 or 20% blended bio-diesel fossil fuel diesel show much reduced effects on these materials and with virtually no effect with B2 (2% blended bio-diesel). Engines lose about 2% power and 3% fuel economy with B20 bio-diesels.
