Abstract
A valve includes an inlet and outlet housing, a flexible one-way valve, and a collar. The flexible valve is locked between the housings. The collar is attached to the inlet housing and extends into the flexible valve. As fluid flows through the valve, the collar supports the flexible valve and prevents collapse due to back flow pressure.
