Abstract:
A testable back pressure valve can include a housing comprising a housing body. The valve can also include a valve seat coupled to the housing, where the valve seat includes a valve seat body having a first cavity and a second cavity, and where the valve seat further includes a first network of channels disposed in the valve seat body. The valve can further include a valve head movably disposed within the first cavity of the valve seat. The valve can also include a piston follower movably disposed within the second cavity of the valve seat, where the valve head is fixedly coupled to the piston follower. The valve can further include a travel piston movably disposed within the second cavity of the valve seat, where the travel piston is moveably coupled to the piston follower.
