This valve has the highest flow capacity with the lowest pressure rise of any valve on the market. For most applications, the rise is under 1 PSI, since the total bypass flow for most systems is 600 lbs/hour or less. The closing flow curve is within 0.3 (3/10) PSI at any flow point on the opening curve. This is achieved by hard-coating, then micro-lapping all of the moving parts. This means the pressure in the fuel system will stay close to the set point on both rising and falling engine RPM. Many valves can go into a “buzz” (hydraulic vibration). This valve is more stable, as it is the only valve on the market with a unique spring arrangement designed to control buzz. The diaphragm has a swiveling “live” center pintle (shown below) that closes down on the seat for very smooth operation. Both the pintle and the seat are lapped for bubble tight close-off. Hard anodized aluminum housing components and a very compact design makes the piece lighter and easier to install in the vehicle. Components are compatible with Gasoline and Methanol. Accepts Kinsler and Hilborn jets; has jet sealing o-ring for restrictor jet. Weighs only approximately 0.45 lbs. 57 PSI to 123 PSI. Also known as a Jet Can.
