For the first time you can achieve precisely repeatable air flow mapping,
using our new unobstructed valve kit and software.
The Pressure Differential Valve is a unique custom research tool never
marketed prior to RTST's production. This tool has been instrumental in
the gaining of proprietary cutting edge technology responsible for
hundreds of race Wins, Championships and Speed Records.
By its design, this tool measures the Pressure Differentials in the valve
flow area without obstructing the flow path of air being tested. The user
can not only obtain accurate, repeatable results but also additional
information not typically compiled in air flow tests using standard
