371VE033 Check Valve for Neoplan

What does a check valve do?

This check valve serves as a critical component within the pneumatic brake system, ensuring unidirectional air flow and maintaining pressure stability. Built with high-strength components, it prevents backflow and protects the system from pressure drops during braking maneuvers.

Vehicle and system compatibility

This specific unit is designed for Neoplan vehicles and is compatible with Neoplan systems. It features three M22x1,5 ports to facilitate precise pneumatic routing within the heavy commercial vehicle chassis.

Installation and maintenance

For proper maintenance, technicians should inspect the valve for leaks using a soapy water test during periodic service. Ensure all M22x1,5 connections remain tight and check that the internal mechanism moves freely to prevent air system contamination or blockage.

Troubleshooting and selection

When performing repairs, always verify that the replacement part meets the 10 bar maximum pressure requirement to ensure safe operation under heavy commercial load conditions.
