Check Valve
Mack

This check valve plays a critical role in controlling fluid flow within the truck’s vacuum power system. It allows fluid or air to flow in one direction only, preventing backflow that could compromise system performance. Constructed from durable, corrosion-resistant materials, it ensures long-lasting operation even under high pressure and continuous use. Proper functioning of this valve is essential for maintaining the efficiency of vacuum-assisted components, such as brakes or other pneumatic systems. Regular inspection and replacement when necessary help sustain optimal system performance.
