Abstract:
Directional control valves with blind shear rings are provided. In one embodiment, a valve includes a piston within an inner chamber of a hollow body having inlet and outlet ports in fluid communication with the inner chamber. The valve includes a shear seal ring positioned in the piston and seated against an interior surface within the hollow body. The shear seal ring includes an interior cavity for allowing fluid communication between the inlet port and the outlet port via the interior cavity depending on the position of the piston. Further, the valve includes a blind ring positioned in the piston. At least a portion of the blind ring is exposed to fluid via the interior cavity of the shear seal ring, and the blind ring prevents flow of fluid from the interior cavity of the shear seal ring through the blind ring. Additional systems, devices, and methods are also disclosed.
