JETWORKS FLOW CONTROL VALVE
The Flow Control Valve provides improved throttle response and much
quicker starts by drying out your waterbox at low rpm and idle speeds.
Tests have shown an average acceleration improvement of 10 feet over
a non-equipped model in the first 50 feet. The Flow Control Valve
allows unrestricted water flow to the Stinger for better top speed.Yet it
controls the amount of water at low speeds for better response. It also
allows for an easier tuning of the Carburetors. It does not interfere with
normal engine or exhaust pipe cooling and is compatible with all
electronic water injection systems. Race Legal for All Classes.Two
Models are available. Both are adjustable. The Standard Flow Control
Valve is preset at 3.5 p.s.i. and is adjusted by adding the supplied
stainless steel shims to increase the spring tension. The Pro-Series is
externally adjustable by turning the outer housing by hand. Pressure
can be tested with pop off gauge. All PWC w/OEM or aftermarket
exhaust systems (except Yamaha’s w/OEM exhaust)
