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.

Double valve constructed from unitary single valves

An energy saver valve includes a first spool () and a second spool () slidably received in a passage () of a housing (). The first spool and the second spool are separate components. The energy saver valve also includes a first outlet port (), a second outlet port (), and a resilient member () located in a resilient member chamber () that biases the second spool towards the first spool. Fluid exits the first outlet port at a first pressure when the energy saver valve is in an initial position, and another passage () provides fluid communication between the fluid in the resilient member chamber and the first outlet port. The fluid exits the second outlet port at a second pressure when the energy saver valve is in an actuated position. The first pressure is less than the second pressure.

Two spool energy saver valve

A double valve is constructed from first and second unitary valve assemblies each having a respective inlet port, a respective outlet port, a respective exhaust port, a respective first cross-mirror port, and a respective second cross-mirror port. A first plate is coupled to the first and second unitary valve assemblies and includes respective passages to provide a common inlet port coupled to the respective inlet ports of the first and second unitary valve assemblies and a common outlet port coupled to the respective outlet ports of the first and second unitary valve assemblies. A second plate coupled to the first and second unitary valve assemblies includes respective passages to provide a first cross-connection between the first cross-mirror port of the first unitary valve body and the second cross-mirror port of the second unitary valve body, a second cross-connection between the second cross-mirror port of the first unitary valve body and the first cross-mirror port of the second unitary valve body, and a common exhaust port coupled to the respective exhaust ports of the first and second unitary valve assemblies.
