Abstract
A hydraulic control valve for controlling hydraulic circuits comprises a valve housing defining a valve bore, a first spool valve slidably positioned within the valve bore and adapted to control a first hydraulic circuit, and a second spool valve slidably positioned within the valve bore and adapted to control a second hydraulic circuit. The first spool valve and the second spool valve are positioned co-axially within the valve bore and are independently slidable within the valve bore to allow the first and second spool valves to control the first and second hydraulic valves independently of one another.
