Abstract: Described are a rotary shear seal valve and a method for switching a high pressure fluid. The method includes applying a fixed force between a planar surface of a rotor and a planar surface of a stator. The planar surface of the rotor includes a fluidic channel and the planar surface of the stator has a pair of ports to receive and provide the fluid. A control signal is applied to a linear actuator coupled to the rotor to generate a controllable force between the planar surfaces of the rotor and stator. The control signal is responsive to a rotational state of the rotor. The total force between the planar surfaces of the rotor and the stator is substantially equal to a sum of the fixed force and the controllable force. The method reduces the wear and extends the lifetime of components in a rotary shear seal valve.
