IS HESITATION ROBBING YOUR CRAFTS OFF-THE-LINE POWER?

The JETWORKS FLOW CONTROL VALVE provides improved throttle response and much quicker starts by drying out your water box at low rpm and idle sppeds. Tests have shown an average acceleration improvement of 12 feet over a non-equipped model in the first 50 feet. The JETWORKS 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.

In a race start situation, the craft is under a slight load while waiting the start, water fills up the water box and exhaust hoses. Upon sudden acceleration all of this water must be forced out quickly before full exhaust flow can occur. During this time the craft feels a slight hesitation and/or sluggishness, especially when the water box is mounted up front and has a rear exhaust.

The JETWORKS FLOW CONTROL VALVE improves response through turns when the throttle is let off for a split second. This drys out the water box while at the same time raising the water pressure slightly in the head pipe of the exhaust. This raised water pressure allows the water injection orifices and/or nozzles to work quicker and more effectively.

Two models are available. Both are adjustable. The STANDARD JETWORKS FLOW CONTROL VALVE is preset at 3.5p.s.i. and is adjustable by adding the supplied stainless steel shims to increase the spring tension. The PRO-SERIES JETWORKS FLOW CONTROL VALVE is externally adjustable by turning the outer housing by hand. Pressure can be tested with a pop off gauge. Both models feature a positive sealing viton on metal seals with a precision calibrated, variable rate spring. This allows for true water flow and pressure management of multiple water lines and dedicated cooling line applications.
