Kinsler Fuel Injection, Inc, 1834 THUNDERBIRD TROY, MICHIGAN 48084 U.S.A. Phone (248) 362-1145 Fax (248) 362-1032 133 KINSLER PRESSURE RELIEF VALVE Model K-140 pressure relief valve has many unique (patent pending) features HIGH FLOW CAPACITY ACCURATE PRESSURE CONTROL FANTASTIC PRESSURE REPEATABILITY METHANOL AND GASOLINE COMPATIBLE COMPACT DESIGN SERVICEABLE IN-THE-FIELD Our unit has the highest flow capacity with the lowest pressure rise of any valve on the market. At 1000 lbs/hr (2.8 GPM) of bypass flow, it only has a 2.5 PSI pressure rise. This is less than 1/7th to 1/4 the drop of the most popular valves we have tested. 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 rails will stay close to the set point on both rising and falling engine RPM. Many valves can go into a “buzz” (hydraulic vibration); ours is more stable as it is the only valve on the market with an available damping option. A unique spring arrangement is also available to further 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. Valves that use a fixed pintle or a ball tend not to shut off smoothly, nor to seal completely. A nice design feature is a replaceable seat. Should the seat get damaged or worn it can be removed and a new one installed. Two 8 AN female inlets, with full flow-through capability to help balance fuel rail pressure fluctuations and a 3 AN pressure gauge port. We can adapt the valves inlets to most AN sizes. 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. © 2017 #12104 K-140
