Product Q&A

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

For water supply and industrial pipelines, swing or resilient seated check valves are recommended. Consider flow velocity, pressure rating (PN10/PN16), and installation. For preventing water hammer, choose slow-closing or damped check valves.

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

Check valves prevent backflow and protect pumps from reverse rotation in fire protection and pump stations. They close automatically when flow stops, ensuring safety and pressure maintenance. Resilient seated or double-door check valves are favored for reliable sealing and low pressure drop.

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

Standard check valves operate automatically with flow direction changes. For systems with frequent flow changes, silent or spring-loaded check valves are recommended for quick, quiet closing, reducing water hammer. High-quality designs with proper damping effectively manage demanding conditions.

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

Check valves prevent reverse flow in HVAC and chilled water systems, protecting equipment like pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliable performance enhance system efficiency and safeguard sensitive components from backflow damage.
