Commercial's VA and VG model valves are contemporary versions of our well-proven A20/A35 units which have provided reliable control of fluid power for over 20 years. The VG models are cast from compacted graphite, a high strength iron alloy that allows us to rate the valves to 3500 psi. VA models are cast from gray iron and are rated at 2500 psi.
