Description
What does a check valve do?
This check valve plays a critical role in the pneumatic brake system by maintaining pressure direction and preventing backflow within the air lines. Built with high-strength components, it ensures the stability of the braking system under heavy-duty operating conditions.Compatible vehicles and engines
Designed for use in MAN vehicles, this component is essential for maintaining consistent air pressure levels. It is also fitted to other heavy commercial vehicles requiring reliable pneumatic control. The valve features three M22x1.5 ports to facilitate precise system integration.Installation and maintenance
For proper maintenance, technicians should inspect the unit during periodic brake system service. It is recommended to check all M22x1.5 connections for tightness and perform a leak test to ensure the integrity of the air circuit.Troubleshooting and inspection
Regularly inspecting the valve for moisture or contamination buildup can prevent unexpected system failures in the braking circuit.OE cross-reference
303.15.0001 (Check Valve Check Valves) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 81521306043.Technical Specifications
