Can someone please tell me what the advantages are between a unidirectional and bidirectional blocking fitting ? I am confused because when I look at the schematic the only difference I see is the pilot line on the uni is not exhausted and the bidirect it is . Thanks in advance to anyone you can assist. |

A unidirectional blocking valve usually will stop flow in one direction when engaged, functioning as a check valve. |
