R-12 Series High-Flow Service Relay Valve for Commercial Air Braking

The H31024 is a high-performance R-12 series service relay valve engineered to accelerate the application and release of the air brakes on heavy-duty commercial vehicles. By being positioned close to the brake chambers, this valve significantly reduces the response time of the braking system, allowing for rapid deceleration and stopping. It is particularly vital for vehicles with long wheelbases or multiple axles, where air travel time from the primary foot valve can result in delayed braking performance. The H31024 efficiently converts low-volume signal air into high-volume delivery air, ensuring maximum braking torque is applied precisely when needed.Construction features include a robust cast-aluminum housing that is resistant to corrosion and designed for superior heat dissipation. The internal piston and sealing elements are precision-engineered to maintain consistent performance and an airtight seal throughout thousands of cycles. Its high-flow design minimizes back pressure, optimizing the efficiency of the entire air brake circuit. The valve is also designed to withstand the harsh environmental conditions of the vehicle chassis, including exposure to moisture, road salt, and dirt, ensuring long-term operational reliability in diverse geographic regions.
