Kinsler Fuel Injection, Inc, 1834 THUNDERBIRD TROY, MICHIGAN 48084 U.S.A. Phone (248) 362-1145 Fax (248) 362-1032 94 HIGH SPEED BYPASS VALVE KINSLER K-140 VALVES 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 (3/10) PSI at any flow point on the opening curve. This is achieved by hardcoating, then 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 falling engine RPM. THE ULTIMATE HIGH SPEED K-140 3967 Complete assembly, 17-37 PSI 3968 Complete assembly, 26-51 PSI 3969 Complete assembly, 34-80 PSI 3970 Complete assembly, 49-106 PSI 3971 Complete assembly, 57-123 PSI 3972 Complete assembly, 72-152 PSI 3973 Complete assembly, 88-230 PSI, requires special spring package, call for details 3161 Restrictor jet holder, has jet sealing o-ring, 6 AN female inlet x 6 AN male flare outlet, screws directly onto K-140 inlet or outlet fitting and seals with o-ring 3988 Adjusting screw with lock nut, 10-32 thread 3989 Vent filter breather, sintered stainless steel, 10-32 male thread 12090 Diaphragm assembly, 'D' style, includes: lower spring rest, pintle, and diaphragms (2) 12091 Diaphragm replacement material ONLY (two pieces) 12087 Spring, 'Inner' 12088 Spring, 'Middle' 12089 Spring, 'Outer' 12085 K-140 mounting bracket, billet aluminum, black anodized, four mounting holes at 1.90" centers 12086 Set of four Vibration Isolation Mounts, for #12085, 5/8" diameter x 1/2" tall, rubber, 8-32 x .490" thread © 2017 #3989 #3161 Exploded view of K-140 Close up of live-action pintle 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 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 this piece lighter and easier to install in the vehicle. Components are compatible with gasoline and methanol . Seven different spring combinations are available for a total adjustable range of 17 - 230 PSI. There is also CUSTOM BUILDUP SERVICE available. Accepts Kinsler or Hilborn jets... has jet sealing o-ring for restrictor jet. Valve is LIGHT , weighs 0.45 lbs. The K-140 High Speed comes complete with : 1- 6 AN male flare inlet fitting, 8 AN port plug for unused inlet port 3 AN port plug for pressure gauge port #3989 vent breather filter #3161 restrictor jet holder
