Product Q&A

Q:How to select the right check valve for water supply and industrial pipelines?

For water supply, pumps, and pipelines, use swing or resilient seated valves. Consider flow velocity, pressure (PN10/PN16), and orientation. For slow closure to prevent hammer, choose damped valves.

Q:What makes check valves essential in fire protection and pump stations?

Check valves prevent backflow and protect pumps from reverse rotation, closing automatically to ensure safety and maintain pressure. Resilient seated or double-door check valves are popular for their reliable sealing.

Q:Are check valves suitable for high-frequency flow changes and automated systems?

Standard check valves operate automatically with flow direction. For systems with frequent flow changes, silent or spring-loaded check valves close quickly and quietly, reducing water hammer. High-quality designs with proper damping handle demanding conditions well.

Q:What are the main advantages of check valves in HVAC and chilled water systems?

Check valves prevent reverse flow and protect HVAC and chilled water systems by safeguarding pumps and chillers. They ensure low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliable performance boost efficiency and shield components from backflow damage.
