A technique facilitates delivery of high pressure actuating fluid, e.g. drilling mud, to a plurality of actuators. The technique employs a valve system in which high pressure actuating fluid is delivered from inside a rotor to outer stator ports on a surrounding stator. The construction and arrangement of the rotor and stator reduces the inherent instability and susceptibility to sticking that can otherwise affect the operation of the valve. |
