Abstract:
A flow control apparatus with a guide housing having one or ports, a breakable bond, and a platform with an upper surface having one or more pistons. The platform and guide housing have a first bonded configuration where the pistons are received in the ports, a breaking configuration, an opening configuration where the platform is movable away from the guide housing, and a misaligned configuration where the platform is displaced with respect to the guide housing. The guide housing has a guide bore and the platform has a guide projection extending into the guide bore. The guide bore has a groove and the guide projection has an extension extending in the groove for transitioning between configurations.
