S…A Inline check valves are used to allow the fluid flow in one direction and stop it when the flow turns back. If the flow turns back, it causes the pump and motor to reverse resulting in reservoir unexpected leakage and spilling accident.

It is important to choose the S…A hydraulic inline check valve, it is small but it may be the key role in the hydraulic systems. Finotek all inline check valves produced is tested with no leakage before delivery to our customers.
