20 I Solenoid valves
as anti-siphon valve according to DIN EN264
This range of high-quality solenoid valves is not
dependent on a specific minimum differential
pressure; the valves operate extremely reliably
with no pressure, at slight differential pressure,
right through to maximum pressure. They are
therefore the valves of choice for installation in
plants where differential pressures fluctuate
greatly and are not possible to determine
precisely in advance. Solenoid valves of the AV
series are approved as safety shut-off devices
according to DIN EN 264 (Registration
No. 5S235/2000) and are particularly suitable
for use as anti-siphon valves in supply
installations for light fuel oil EL.
