Product Q&A
Q:How to select the right check valve for water supply and industrial pipeline systems?
A:
For water supply and industrial pipelines, swing or resilient seated check valves are recommended. Consider flow velocity, pressure rating (PN10/PN16), and orientation. For preventing water hammer, choose slow-closing or damped check valves.
Q:What makes check valves essential in fire protection and pump station systems?
A:
Check valves prevent backflow, protect pumps from reverse rotation, and ensure system safety. 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?
A:
Standard check valves function automatically with flow direction. For systems with frequent flow changes, silent or spring-loaded check valves are optimal, closing quickly and quietly to reduce water hammer. Quality designs with proper damping handle demanding conditions well.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves prevent reverse flow in HVAC and chilled water systems, protecting pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. Their compact, reliable design boosts system efficiency and safeguards sensitive components against backflow.
