Haldex 109264X R-12P Pilot Relay Valve for Air Brake Systems

The Haldex 109264X R-12P Pilot Relay Valve is a critical component in commercial vehicle air brake systems, designed to provide rapid and reliable brake application and release. This relay valve acts as a remote-controlled brake valve that uses air pressure signals from the brake valve to control the delivery of air from the supply reservoir to the brake chambers, ensuring faster response times and more efficient braking performance.

Key Features:

• R-12P configuration for pilot-operated relay functionality
• Enables quicker brake response by reducing signal travel distance
• Proportional air delivery matches control pressure from treadle valve
• Durable construction designed for heavy-duty commercial vehicle applications
• Helps reduce pressure loss in long brake lines on trailers and rear axles
• Direct replacement for maintaining optimal brake system performance

This pilot relay valve is commonly used in truck and trailer brake systems where the brake valve is located far from the brake chambers. By positioning the relay valve closer to the brakes it serves, the system achieves faster brake application and release, improving both safety and vehicle control.
