Tractor Protection Valve

The EM34550 Tractor Protection Valve delivers critical safety and performance for heavy-duty truck braking systems. Designed to isolate the tractor’s air supply from the trailer during air loss, it prevents system failures and helps maintain driver control in hazardous situations. The valve’s durable construction withstands constant vibration, pressure changes, and tough road conditions. It provides consistent airflow regulation, preserves tractor air integrity, and extends the lifespan of downstream brake components. Whether used in fleet maintenance or OEM-level replacements, this valve ensures reliable operation and improved overall system safety.
