<p>A valve (18) includes an inlet (12) and outlet (14) housing, a flexible one- way valve (18), and a collar (30). The flexible valve (18) is locked between the housings (12, 14). The collar (30) is attached to the inlet housing (12) and extends into the flexible valve (18). As fluid flows through the valve (18), the collar (30) supports the flexible valve (18) and prevents collapse due to back flow pressure.</p> |
