Abstract
A double valve includes a first unitary valve assembly and a second unitary valve assembly. Each unitary valve assembly includes a first outlet port, a second outlet port, and a spool. A first pilot assembly and a second pilot assembly are coupled to the first unitary valve assembly and the second unitary valve assembly, respectively. A plate is coupled to the unitary valve assemblies and includes a passage to provide a first common outlet passage that is coupled to the respective first outlet ports of the unitary valve assemblies and a second common outlet passage that is coupled to the respective second outlet ports of the unitary valve assemblies. When the spools are in a first position, fluid flows through the first common outlet passage, and when the spools are in a second position, the fluid flows through the second common outlet passage.
