A Check Valve is used to control the flow of hydraulic fluid in the service brake line unit. It allows fluid to flow freely in one direction while blocking the flow in the opposite direction. By preventing backflow, the check valve helps to protect the hydraulic unit from damage caused by pressure surges, fluid contamination, or unintended movements.Attributes:• Maximum operating pressure of the valve is 34450 KPa, which ensures the safe operation of the unit under high-pressure conditions• Hex profile allows for facilitating the secure tightening or loosening of the valveApplications:A Check Valve acts as a one-way flow regulator and backflow prevention part in the hydraulic service brake line unit.
