Failsafe Pilot Supply Selector Valve |
| 摘要 |
A failsafe pilot selector valve may include at least one inlet port, a first outlet port, a second outlet port, and a biasing element. The failsafe pilot selector valve may have a first end position with the at least one inlet port in fluid communication with the first outlet port, a second end position with the at least one inlet port in fluid communication with the first outlet port, and an intermediate position between the first end position and the second end position with the at least one inlet port in fluid communication with the second outlet port. The biasing element may provide a biasing force to move the failsafe pilot selector valve to the first end position. The pilot selector valve can alternately provide pilot fluid to primary and redundant control elements of a redundantly controlled system in fluid communication with the outlet ports. |
