Check valve 1 inch, overpressure valve, pressure relief, diesel heating oil

Non-return valve 1 inch, suction basket, pressure relief valve diesel heating oil

This special non-return valve has an integrated safety valve.

You can see this in the detailed photos in the middle of the plastic axle.

This allows for the release of possible overpressure, which can arise, for example, when the hose is exposed to sunlight.

The dangerous overpressure is then discharged through the valve back into the tank from which the diesel/heating oil is drawn.

This prevents the dangerous bursting of the hose caused by the thermal expansion of the medium.
