30 lip 2022 · Swing check valves are common check valves used in water and wastewater applications. They are cost-effective, are made of a wide range of materials, and have different designs for specific functionality.
A swing check valve allows forward flow and blocks the reverse flow. It provides a strong option for uni-directional homogenous flow applications. In this article, you will review a swing check valve diagram, operating principles, types, k-values, installation concerns, and applications.
A swing check valve (or tilting disc check valve) is a check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow.
A swing check valve allows full, unobstructed flow and automatically closes as pressure decreases. These valves are fully closed when the flow reaches zero and prevent back flow. Turbulence and pressure drop within the valve are very low.
Swing check valve consists of a circular disc which swings on a hinge pin. This check valve can be mounted horizontally as well as vertically. Preferred orientation is horizontal as there is tendency for disc to stay open if flow reversal occurs very slowly.

27 lip 2023 · Swing check valves allow fluid flow in one direction while preventing backflow in the opposing direction. They have a hinged disc known as the “swing disc” or “clapper,” which swings on a hinge or pivot at the valve’s top.
