Product Q&A
Q:How to select the right check valve for water supply and industrial systems?
A:
For water supply, pump outlets, and industrial pipelines, swing or resilient seated check valves are best. Consider flow velocity, pressure rating (PN10/PN16), and installation orientation. For preventing water hammer, choose slow-closing or damped valves.
Q:What makes check valves essential in fire protection and pump systems?
A:
Check valves prevent backflow and protect pumps from reverse rotation in fire protection and pump stations. They close automatically when forward flow stops, ensuring safety and maintaining pressure. 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 operate automatically based on flow direction. For frequent flow changes, silent or spring-loaded check valves are ideal as they close quickly and quietly, minimizing 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?
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 when open. Their compact design and reliable performance enhance system efficiency and safeguard components from backflow damage.
