S…A Check ValvePDF

In-line check valve is connected in inner threads for hydraulic systems, it usually mounted before actuators, like pumps or some certain valves to prevent the fluid flow back forward. These valves are also installed in the supply line in auxiliary hydraulic system where the pressure expected to surpass the main hydraulic system.

There are many thread standard types of the in-line check valve, Finotek suppliers Metric, Inch threads, or customized threads as per clients’ requirements. There are ball or poppet sealing type of in-line check valve, please consult for one type.
