These valves have a typical flow port relief cartridge that go on VA and VG20/35 stackable valves.

You have two choices for these valves. One is a pilot valve that is driven by an adjustable screw cartridge that allows the flow to go up to 70 gpm and pressures that go from 500 to 5000 psi. The second option is a differential slug adjustable cartridge that lets the flow go up to 40 gpm. There are three pressure fields that go from 500 to 1000 psi, 1000 to 2500 psi and 2500 to 3500 psi.

The block is a SAE-16 pressure port and a SAE-20 tank port.
