Default Turbine fuel system setup

This is a question for all you Hydraulics experts out there. In our large turbine fuel system setups I do like the hi flow nipples and lines "8mm" from the vent to the tanks to the air trap. My question is from the UAT, CAT "airtrap" to the fuel pump or power pack with some turbines. 8mm coming out of the air trap has to be reduced to 6mm going in to the power pack. Dan and I have just been using a Festo reducer, but wouldn't it be the same thing to just have a 6mm nipple on the air trap alleviating the need for the festo. Also with power packs the festo shutoff valve is between the airtrap and the power pack, is there a 8mm to 6mm festo shutoff valve.

Thanks
Doug Arnold

I have never seen a reducing SOV. But you can easily slide a 6mm tube into an 8mm tube, with minimum risk of leakeage and no need for a reducer.

in my opinion, i don't see how we are gaining anything with 8mm coming out of the airtrap but being reduced to 6mm at the powerpack. just have the 6mm nipple at the airtrap then have 6mm shut off no need for reducer one less point of failure and nicer install. I think buying airtraps with the custom size nipples for each application would be nice

MAP hi flow and I think the BVM hi flow come with a step down, not a 100% on the BVM but I know the MAP does.
