Drilling a power beyond port in Commercial valve end plate
Drilling a power beyond port in Commercial valve end plate
(OP)
I understand that since I cnat locate that end plate with the power beyond port, that I can drill and tap a port for it. Does anyone know of any tip or tricks that might keep from ruining this setup. Thank you for reading.

The bigger problem is how are you going to block the pressure galley from the tank galley? The end plate does not look think enough to have a provision for a plug.

Use at least an auto feed drill press with coolant. Remember their usually soft cast iron and require low feed rates.
Be sure that when you put the cap back onto the valve you torque the valve to the proper torque setting. V20 is IIRC 32 lbft and V40 with four studs is 25 lbft. If you incorrectly torque the valve you can bind the spools in the valves. Check for free movement of all spools after assembly.
