Abstract
A method of operating an actuator in mud having debris and lost circulation material is described. The method includes closing a servo valve positioned within a valve housing. The valve housing has a plurality of fluid vents positioned downstream of the servo valve and a plurality of debris vents positioned upstream of the servo valve. Dimensions of the plurality of fluid vents are less than dimensions of the plurality of debris vents. Closing of the servo valve creates a first fluid path such that fluid flows from a mud pump at a surface into the plurality of debris vents and out of the plurality of fluid vents shielding the servo valve from debris and lost circulation material.
