    摘要: The subject matter of this specification can be embodied in, among other things, an apparatus that includes a valve with a valve housing having an axial bore, a first inlet port, a first outlet port, and a piston located within the axial bore and having a first fluid passage and configured to allow reciprocal axial movement of the piston within the axial bore between a first position in which the first fluid passage aligns axially with the first inlet port and the first outlet port to form a first fluidic circuit, and a second position in which the piston blocks at least one of the first inlet port and the first outlet port. The apparatus also includes a lockout assembly configurable to fix the piston into a selected position in a first configuration, and not interfere with reciprocal axial movement of the piston in a second configuration.
