 Product Description


The APR R1 diverter valve was designed to be the ultimate solution to the problem of unreliable factory and
aftermarket diverter valves and to be the leader in performance. Although most are of good design, factory
diverter valves are built in a very conscious manner and the materials and overall life and reliability suffer. For
the performance enthusiast, the diverter valve is an important component whose proper operation is
paramount to optimal engine operation.

APR's R1 diverter valve addresses all of the reliability problems of the factory-supplied diverter valves and
aftermarket replacements and takes performance to the next level. The R1 is a diaphragm-based valve. A
diaphragm is the best option for a diverter valve for several reasons. First off, a diaphragm has negligible
friction. Piston-based valves have considerable friction from the piston, o-ring, and bore assembly. The lower
friction R1 diaphragm equates to faster response and better overall performance. Secondly, diaphragms do
not require the periodic greasing that piston-based valves do. Piston-based valves must be qreased periodically
(usually every year or sooner), requiring removing the valve from the car, disassembling and reassembling the
valve. The APR R1 was designed to be maintenance free for the life of the product. Thirdly, a diaphragm based
valve will never have a stuck piston. Piston-based valves periodically incur stuck pistons (especially if the
required maintenance schedules are not followed.) Due to the lack of a piston, the APR R1 solves this problem.

The R1 is designed for optimal performance. The main body of the valve is investment cast in an aluminum alloy.
By utilizing this casting process in lieu of a more conventional machining process, APR was able to optimize the
internal geometry of the valve to provide the ultimate in flow performance. This geometry cannot be created
utilizing conventional machining. As such, the APR R1 has much better flow characteristics than other diverter
valves. Combined with the low friction diaphragm assembly, this equates to a valve that is truly a performance
leader.
