Screwed SS316 and SS304 Check Valve Cast Steel Swing Check Valve
Swing check valve, as the name implies, also uses a swinging disc to allow or block
flow. The difference between the two is in the body design. Swing
check valves are not designed for extremely tight spaces like the
wafer check. They have molded bodies around the area where the disc
opens up. This is the most important difference between the two
types of valve.
Swing check valves on the other hand, have a molded body that
creates room for the disc to swing open fully, thus allowing full
flow. As you can imagine, this is immensely important if your
application requires full flow. For this reason, we recommend wafer
check valves for applications where flow is not an issue, and swing
check valves when a full port valve is required.
