This 12VDC valve boasts 3500 PSI operating pressure, 11 GPM flow (@50 PSI pressure drop), -8 female ports and draws less than 1.7A. It is simply the best we've ever seen for this kind of duty. The lightweight aluminum valve body is hard anodized for long life. The assembly includes a brass pill plug, button head plugs in one of the IN and OUT ports, and -6 male fittings for attaching your hoses. This body accepts standard Enderle screw-in bypass pills which are not included but RBS can supply at an additional cost if the racer chooses. The coil can be rotated to position the non-polarity sensitive leads in any direction desired. The thru holes in the valve body allow bolting the valve to the vehicle with 1/4" socket head cap screws (not supplied).
The most common use is as an enrichment device in a mechanical fuel injection system. Since this valve is always open until activated, the user would strategically split up the main pill area and put some of it in this valve. When enrichment is desired, the valve is activated and the bypass area in the valve is effectively subtracted from the system causing a richer air fuel ratio.
For example screw blower applications typically need enrichment at the top end vs. a lean out. When coupled with a timer, or pressure switch, this valve can be used as a "low speed lean out" by enriching the fuel system off the starting line for the first 80-100'. A richer mixture for best torque off the line needs to be changed well before half track and at that point the valve is switched off (open). This strategy works best with big motors, big blowers in heavier cars with converters. This valve can also be used for traction control purposes by exaggerating a rich condition and safely getting rid of power when activated.
This valve comes with gas and methanol compatible seals. Racer must specify nitromethane if that is the fuel of choice to be used with the valve. This valve is supplied with plain 16" wire leads for connection to your vehicle. RBS offers a couple of standard connection options at additional cost which the racer can check out under part number #395-0013 Molex or #395-0014 Deutsch.
