SHUTTLE VALVE WITH DURABLE SOFT SEAL |
| 摘要 |
A shuttle valve having a cage fixed in the cross bore thereof by opposed inlet adaptors extending into opposed first and second inlets is provided. A shuttle is reciprocally located in a bore in the cage, to selectively seal one of the first or second inlets from fluid communication with the valve outlet. The shuttle may be spring biased to maintain one of the inlets in the closed position without the need to apply a pressure into an inlet of the valve. |
