Oventrop Oilpur heating oil single-line filter with return feed, 3/8", shut-off valve

Oventrop oil filters are made for single line systems with return flow feed. For those oil filters with return flow feed there is a built-in vent valve for the startup. With return flow systems, the heating oil reflowing from the burner pump is directly fed back to the burner pump via a pressure valve in the filter head on the suction side. Due to the loose mounting flange, these oil filters can be universally mounted  at ¼" up to ½", thus the whole lining system gets a firm fit. By insert choice (sintered plastic, sintered bronze, nickel screen cloth or felt) or by use of the spin-on filter, filters can be optimally adapted to specific circumstances.   Consisting of: - fast closing shut-off valve - vent valve for startup - housing and valve made of brass, with mounting bracket - transparent cup for suction operation - for hose clip connections 6, 8, 10 or 12 mm (connection sets must be ordered separately)
