This is probably the most common check valve in use today and is a full-port design, meaning the disc, when fully open, is out of the flow stream. This style of check valve is a good choice in applications that have a high percentage of solids and a lower on/off cycle count. Due to the travel distance of the disc, … See more This valve is similar to the swing check and a little better in terms of closing because of the coiled springs that assist the two cantilevered … See more These full flow valves typically incorporate a center guided stem-disc assembly along with a compression spring. This means the disc stays in the flow stream. The media flows around it and … See more Benefits of using a properly sized and positioned silent check valve: 1.
