Re: New member. Building D8
The CAD drawing is a little misleading, that return line is from the end of valve.
tank - pump - tee in pressure gauge - valve - prv - tank the other port on each end are returning to the tank & each line has an inline filter. The prv is Y'd to other returning line b/c where's the oil gonna go when it enters the prv? There's an in port & an out port on the prv. You understand how a prv works, right? A steel ball covers the inlet port, a heavy coil spring applies pressure to steel ball & an adjustable screw tensions up the spring so it takes a certain amount of oil pressure to compress the spring & allow oil past the steel ball. The oil entering the prv goes out a different free flow port.
