I am adding a grapple to my FEL on my kubota b21. My question is... to get pressure to my new grapple valve should I go from the pump pressure line to the new valve "in" then out via PB to the FEL valve "in" ? or should I tap into the FEL PB to get the pressure to the new valve then out via PB to the existing BH.
If i asked that correctly, i understand not to "T" into a pressure line. so in short we go into a valve with pressure and out via PB to the next valve. does it matter what valve get the pressure from the pump first?

Thanks

While "technically" it does not matter, it is far more common to feed the new valve from the PB of the FEL valve making it the second valve in the series.

I used an electric diverter valve poclain #kv-6/2-6 to reroute my curl cylinders , I added a tee on my fel control lever and installed a momentary switch where I can reach it with my thumb hold button to close/ open grapple release button to curl bucket I was skeptical but it is great and by far the cheapest route.

I used an electric diverter valve poclain #kv-6/2-6 to reroute my curl cylinders , I added a tee on my fel control lever and installed a momentary switch where I can reach it with my thumb hold button to close/ open grapple release button to curl bucket I was skeptical but it is great and by far the cheapest route.

The cheapest route? Really? How much did that diverter cost?

Here is a photo of my B21 with a lever-actuated spool valve on the FEL
cross bar, plumbed from the FEL valve PB connection. This one is Brand
Hydraulics, and you can get a valve like this for under $100. The 4-in-1
control on my Kioti (single solenoid-actuated spool valve) was even less
money (less than $50 for the valve). All setups need some hoses and
fittings. A full diverter plus manifold runs well over $100 from what I have
found.

the total cost for my setup was 150.00 no manifold needed a power beyond plug by itself would have been 40.00 not to mention running new lines the length of my fell arms and securing them safely, all I needed was two 36 inch 3/8 hoses ,and qds I needed either way.yes REALLY
