A DVG80 is a sectional type directional control valve that is rated for an operating pressure up to 3500 PSI (250 bar) with flows up to 120 GPM (450 liters per minute). This model valve has proven itself over the years to offer excellent performance and reliable service.

The combination inlet/outlet casting has a high and low pressure port on both the top and side faces. The system relief valve is pilot operated and is screw adjustable. Mid-section inlets are offered as a split flow or combined flow types, which splits or combines the flow of one or more pumps to downstream work sections, and a two-position selector type mid inlet, which can be shifted to provide split flows in one position and a combined flow in the other. In the combined flow mode, flow from the second pump is directed to all downstream working sections to give 2-speed operation.

Outlet covers can have high and low pressure ports on both the top and side. Internal coring allows a standard low-pressure outlet to be easily converted to a pressure beyond type. Outlet covers can also contain a relief valve.

All working sections are 3 inch (75 mm) wide allowing them to be ported up to 1¼ inch (32 mm) split flange or SAE 24. Relief valves with anti-cavitation checks are available for work sections. All work sections have parallel circuitry except for the fourth position float with tandem circuitry.
