Continental Manufacturing Air Safety Protect Valve

Continental Manufacturing Air Safety Protect Valve

This is a Sealco 140 series series pressure protection valve. It serves as a critical safety component in the pneumatic system of a rear discharge concrete mixer, specifically for accessories like the water tank pressurization circuit. The valve works by isolating the accessory circuit from the main air brake system. This valve automatically closes once the system pressure falls to 80 PSI, preserving the remaining air for safe brake operation. This part is essential for maintaining the safety and integrity of the truck's primary air system during operation.

Key Features
