Check valve apparatus and methods
A check valve apparatus includes at least one first test channel including a first pathway extending through a valve body and in communication with a flow path. The pathway is configured to receive a test stick for inserting through the pathway of the test channel to engage a disc such that the disc moves from the open position to the closed position. In further examples, methods for testing a check valve include the step of moving an end of a test stick to engage a downstream face of a disc such that the disc is moved against a bias of a biasing device from the open position to the closed position. The method further includes the step of inspecting an interior portion of the check valve apparatus.
