TORQUE TEK ADJUSTABLE OVERFLOW VALVE

NOW you can control your Cummins®P7100 fuel pressure with a turn of a wrench!

 

OFV030 - 30 PSI

* DTT Assassin mechanical pumps

* Glacier Diesel Fuel Boss belt drives

* Ford® 6.0/6.4 to Cummins® conversions

* Aeromotive A1000 pumps

 

When doing flow calculations, it's critical to know the actual pump output in gallons per minute (GPM) so the entire fuel system can be evaluated based on this number. I've found over the years that pump manufacturers "fudge" the numbers on the high side to give them bragging rights.

TORKTEK built 12 different valve bodies with different inlet diameters and enlarged exit holes with the number of them increased. With each prototype valve body they tested a different size stainless ball. So, they tested 15 ball diameters with 12 different valve bodies. A total of two days testing.

What were they looking for? Fluid dynamics. They know that a combination of valve and ball diameter will produce "a sweet spot". The valve will flow at the rated pump GPM and maintain linear pressure readings. What they did find is a change of .001 in diameter totally changed how the valve worked!

The result resembles a stock overflow valve but the seat depth is different, the ball diameter is not stock, the inlet hole is

enlarged and the exit holes are now six total.

 

We now sent the three best performing valves for testing on a Dodge®Cummins® 12V.  Based on the flow bench numbers we knew which valve would work but wanted to test in real world conditions. As expected, prototype valve 5B worked like a charm. Fuel pressure stayed close to 30 up to about 2200 RPM and climbed to the mid fifties at full power. They were pleased with the results.

The OFV030 wasn't designed with the Cummins® 12V into a Ford® 6.0 and 6.4 truck conversion. Customers kept calling about using the stock frame rail pump with the Cummins® 12V. They tried our OFV010 and 020 but still had high fuel pressure. After installing the OFV030, fuel pressure smoothed out to about 35 to 45 PSI.

If you want to use either the Assassin or Fuel Boss on your Cummins®12v, YOU NEED THIS VALVE.

The OFV030 is fully adjustable from 20 to 40 PSI while the OFV035 is factory set to 45 PSI. (adjustable from 30 to 65 PSI)
