- Ideal for shut-off heating oil pipe sections (e.g. by means of solenoid or non-return valves) which are subject to considerable temperature differences
- Materials resistant to biofuel and biodiesel mixtures with max. 30 % FAME
- Watertight up to 10 m water column - ideal for use in flood hazard areas
Used to limit pressure increases in closed pipe sections resulting from expansion caused by temperature changes. Suitable for heating oil pipe sections which are closed at both ends (e.g. by means of solenoid or non-return valves) and which are subject to considerable temperature differences (e.g. due to oil pipe heaters).
Suitable for fuel oil EL (DIN 51603-1), diesel fuel (EN 590), liquid fuels as per DIN SPEC 51603-6 and DIN/TS 51603-8 as well as biofuel and biodiesel with a maximum of 30 % FAME (EN 14214). This product is therefore ideal for all ecologically upgraded fuel oil consuming systems that use the new paraffinic fuels HVO or GTL as an admixture or 100 %. Also for use in flood hazard areas and flood risk areas.
