Description
Part Description:
V408 Check Valves feature a hard seat all stainless construction and are suitable for use with water, oil, and gas up to 1000 psi as well as steam up to 150 psi. They are rated for use up to 150°C (302°F).
Swing vs Spring:
Swing check valves utilize a disc attached to a hinge which allows it to swing freely. When there is downstream pressure, the disc swings away from the valve seat to allow the liquid to flow through. Reverse flow is stopped by the disc swinging back into place due to gravity or back pressure. Generally, swing check valves allow for higher flow capacity compared to spring check valves but are often noisier and are limited by their orientation.
Spring check valves are suitable for use in both vertical and horizontal orientations and are ideal for applications that require quick responses to flow changes. They use a closing mechanism, such as a disc or poppet, combined with a spring that allows for downstream flow but stops reverse flow altogether. When compared to swing check valves, spring check valves tend to be more compact in design, making them suitable for installation in tight spaces. They also tend to be quieter, while the spring mechanism ensures a faster response to backflow.
