Product Q&A

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

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

Q:Why are check valves crucial in fire protection and pump stations?

Check valves prevent backflow, protect pumps from reverse rotation, and ensure safety. Resilient seated or double-door check valves offer reliable sealing.

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

Standard check valves operate automatically with flow. Silent or spring-loaded check valves close quickly, reducing water hammer in systems with frequent flow changes. 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 are crucial in HVAC and chilled water systems to prevent reverse flow and protect equipment like pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliable performance maintain efficiency and protect components from backflow damage.
