Description
What is a Swing Check Valve?
A swing check valve (In piping schematics, the swing check valve is typically shown using the non-return valve symbol, representing one-way flow) is a mechanical device that allows fluid to pass in one direction while automatically preventing reverse flow.
It operates through a hinged disc mechanism that swings open with forward flow and closes when flow reverses, ensuring reliable protection against back pressure.
This design is particularly useful in fire protection networks, HVAC systems, and water distribution lines, where the check valve cracking pressure and reliability are crucial for system safety.

FAQs
1. How to install a swing check valve?
Install the valve in the horizontal or vertical position (flow upwards) with the arrow on the body indicating the direction of flow. Ensure proper alignment of the flanged ends and avoid stress on the pipeline during tightening for best sealing performance.
2. Is a swing check valve a backflow preventer?
Yes. A swing check valve automatically closes when reverse flow occurs, effectively acting as a backflow preventer in piping and fire protection systems.
3. What are the three main types of check valves?
The main types include swing check valves, lift check valves, and spring (or silent) check valves, each designed for specific flow and pressure conditions.
4. What is the difference between swing and non-slam check valves?
A swing check valve uses a hinged disc that swings freely, while a non-slam check valve closes faster using a spring mechanism to minimize water hammer in high-velocity systems.
5. What’s the difference between a swing check valve and a spring check valve?
The swing type relies on gravity or reverse flow to close, suitable for large flow rates, while the spring type uses internal tension for faster closure in high-pressure or vertical systems.
6. What operation condition is suitable for a swing check valve?
It is ideal for low to medium flow velocities in horizontal or upward vertical pipelines, handling clean water or fire suppression fluids under pressure up to 365 PSI.
