R1 Diverter Valve Blue Spring Upgrade
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.
APRs 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.
The materials used in the R1 are standard setting.
The diaphragm is created out of high temperature material and
incorporates a Nomex fabric reinforcement layer for enhanced
durability and a diaphragm that will never tear. The alloy main
body is finish machined at APR and receives a
multilayer corrosion resistant and cosmetic enhancing finish. All
machining and final assembly takes place at APR
headquarters in the United States for optimal quality control and
consistency.
