S…A Check ValvePDF

Inline non return valve uses for hydraulic systems with pipe line connection, the are two different inner structure for the in  non return valve, ball sealing and poppet sealing. The ball sealing type is easy to manufacture and cost it cheap, but there is short service life, on the other hand, poppet type sealing is reliable and long term operation, but it is litter higher production cost than ball type.

What Finotek makes the inline non return valve is tested by different pressure to confirm the leakage of the valves, the flow pressurized into the valve  chamber by hydraulic and out directly, but the flow will be completely blocked on converse side, which call it not return or leak-free isolation in one direction.
