TRP has you covered with a comprehensive range of valves to suit most makes and models of truck and trailer in the Australian market. Tested in the harsh Australian environment for many years, TRP Air Valves are the great value alternative that doesn’t compromise on safety or quality. Air valves play a vital role in controlling and regulating the flow and release of air throughout the air brake system. Whether it’s an air valve on your truck or trailer, it’s crucial that each valve performs exactly as it’s meant to ensure a working braking system. With the critical role that braking has in keeping you on the road, you need the peace of mind that comes with knowing the valves you choose are going to perform as intended.

• The air brake system is self-sufficient and there is no need to maintain, check or fill fluid levels.
• Air is unlimited so the brake system can never run out of its operating fluid unlike hydraulic fluid.
• Air line couplings are easier to attach and detach than hydraulic lines. This eliminates the risk of air getting into hydraulic fluid.
• Air is not only used for operating valves and S cams, but also stores potential energy in the air tank. This is important if the compressor fails as the air tank will still contain sufficient air to stop the truck.
• Can still work even with considerable leakage.
