Working Principle
A hydraulic return check valve is a valve that allows oil to flow in one direction only. When oil flows from the oil inlet to the oil outlet, the valve core is pushed open by the spring force under the action of oil pressure, and the oil passes smoothly. When the oil tries to flow back from the oil outlet to the oil inlet, the valve core is tightly closed under the combined action of the spring force and oil pressure to prevent the oil from flowing in the opposite direction.
Function
- Prevent oil backflow: Ensure that the oil in the hydraulic system flows in the specified direction to avoid problems such as unstable system pressure and malfunction of actuators caused by oil backflow.
- Protective element: It can prevent oil backflow caused by sudden changes in system pressure or external factors from damaging hydraulic pumps, hydraulic cylinders, hydraulic motors and other components.
