The pressure, or vacuum, relief valve is designed to be fitted into each compartment on a road tanker.

The road tankers carry hydrocarbon liquids, anything from Diesel to Motor Spirit, and can have up to 7 compartments carrying 40,000 litres usually a mixture of spirit and diesel.

Due to the nature of the product all protrusions into the compartments must be conductive and therefore be at the same potential throughout the whole of the tanker.

Fairfax 3D design were looking for a cost effective material from which to manufacture the valves, that offered very good conductivity, corrosion resistance and the opportunity to design a robust part offering a good balance of weight to performance.

LATIOHM 66-07 PD08 G/30 met all these criteria, offering a surface resistivity of 1 x 10^3 Ohms in combination with the strength of a reinforced nylon 66.

The compound is made from 30% glass fibre reinforced PA66 with the addition to this matrix of carbon fibres and other additives to obtain an electrically conductive material. Simple to mould even on ordinary equipment thanks to its well manageable shrinkage, LATIOHM 66-07 PD08 G/30 is also an excellent choice for the price/performance ratio.
