The swing check valve is placed on a disc that swings on a hinge or shaft. The disc swings into its position to stop backflow once the flow has been stopped. To enable forward flow, the disc pivots away from the seat. The return flow and disc weight both affect how well the valve closes. Here are some of the features that we need to know:
Features of Swing Check Valve
Here are a few things you should note before choosing the top swing check valve manufacturers:
- The bonnet/disc configuration makes maintenance simple.
- Maximum sealing performance is ensured by the disc’s thorough vulcanization using EPDM rubber (up to DN 300).
- The disc’s lip sealing assures tightness.
- The valve may be opened and closed with little effort using a lightweight disc.
- The disc has a small range of motion horizontally and vertically, allowing it to close tightly.
- Bolts were used to secure the hinge around the shaft, removing play and ensuring durability.
- A full bore ensures low head loss.
- Ductile iron with an epoxy coating that complies with EN 14901 and DIN 3476 part 1.
Applications of Swing Check Valve
Swing check valves are used in various industries to regulate and transport corrosive media, such as water, steam, oil, nitric acid, acetic acid, solid oxidizing medium, and other media. They offer good support for clean process media, but spring check valves offer better service for heavier crudes, distillates, and dense and heterogeneous material.
