A double valve (110) includes a first unitary valve (111) assembly and a second unitary valve assembly (112). Each unitary valve assembly includes a first outlet port (188a, 189b), a second outlet port (189a, 188b), and a spool (180, 181). A first pilot assembly (113) and a second pilot assembly (114) are coupled to the first unitary valve assembly (111) and the second unitary valve assembly (112), respectively. A plate is coupled to the unitary valve assemblies and includes a passage to provide a first common outlet passage (140a) that is coupled to the respective first outlet ports (188a, 189b) of the unitary valve assemblies and a second common outlet passage (140b) that is coupled to the respective second outlet ports (189a, 188b) of the unitary valve assemblies. When the spools (180, 181) are in a first position, fluid flows through the first common outlet passage (140a), and when the spools (180, 181) are in a second position, the fluid flows through the second common outlet passage (140b). |
