Applications of T-Way Valves

In the automotive industry, T-way valves are key components used in cooling, braking, and air conditioning systems. In cooling systems, the T-way regulates antifreeze flow, guiding some liquid into the auxiliary coolant tank to buffer pressure at high temperatures and assisting in the system's backflow of coolant to maintain circulation at low temperatures. The coolant level is also visually monitored using the auxiliary coolant tank's markings. In braking systems, the T-way valve connects the automatic branch pipe, auxiliary air cylinder, and brake cylinder, precisely controlling the compressed air path to achieve braking and releasing functions. In air conditioning systems, the T-way valve is used at rectangular straight-through T-pipes or gusseted pipes, adjusting the airflow and pressure of the branch pipe to ensure proper airflow distribution for the air conditioning system. Its sealing relies on O-ring seals, and aging issues must be considered. In laboratory exhaust systems, 90-degree right-angle tees may lead to energy loss, control vibration, and safety hazards, with a local resistance coefficient (ζ) typically between 1.0 and 2.5. In contrast, 45-degree wye tees in the direction of airflow have a local resistance coefficient of only 0.2 to 0.35. Authoritative domestic and international standards recommend 30° to 45° angled insertion. When space is limited, "shoe-tap" connectors can be used to provide cushioning. During installation, branch pipes should be connected from above the top or side horizontal centerline of the main pipe, and connection from the bottom is strictly prohibited.
