An electronic valve is placed in line with a casing in a well. The electronic valve includes a housing having plural ports that are blocked; a valve configured to initiate unblocking of the plural ports to allow fluid communication between the bore of the housing and an outside of the housing; and a deformable seat device having a body placed inside of the bore of the housing. The deformable seat device is configured to have a given diameter D3 for at least one of first and second ends of the body when the plural ports are blocked, and a smaller diameter when the plural ports are unblocked.
