High Speed Bypass Valve KIN-3981

-6AN, 57-123 PSI

KIN-3981

N-3981

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/hr or less. Extremely smooth operation. the closing flow curve is within 0.3 (./10) PSI at any slow point on the opening curve. this is achieved by hardcoating, the microlapping all of the moving parts. this means the pressure in the fuel system will stay close to the set point on both rising and failing angine RPM Many valves 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 deighned to controll buzz. The diaphragm has a swiveling "live" centre pintle 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 aliminium housing components and a very compactdesign makes this lighter and easier to install in the vehicle. Components are compatible with gasoline and methanol.
