Message:
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.

A bidirectional blocking valve usually is a valve that stops flow in both directions when engaged.

I can not give any guidance on application suitability, except that pilot line connections can be more complicated for bidirectional blocking valves.
