General Description
Check valves are two-port valves with two openings in the valve body. One opening is for air, gas or fluid (the media) to enter the valve, the inlet port. The other opening in the valve is for the media to exit the valve, the exit port. Like all check valves, spring loaded check valves require no external control to work. Excluding the spring, spring loaded check valves possess the same basic design elements as all other check valves.
