Product Q&A
Q:How to select the right check valve for water and industrial systems?
A:
For water supply, pump outlets, and pipelines, swing or resilient seated check valves are recommended. Consider flow velocity, pressure rating (PN10/PN16), and installation. For slow closure to prevent water hammer, choose slow-closing valves.
Q:What makes check valves essential in fire protection and pump systems?
A:
Check valves prevent backflow and protect pumps by closing when forward flow stops, ensuring safety. Resilient seated or double-door check valves are popular for reliable sealing and low pressure drop.
Q:Are check valves suitable for high-frequency flow changes and automated systems?
A:
Standard check valves auto-operate with flow direction. For frequent changes, use silent or spring-loaded check valves to minimize water hammer. High-quality designs with proper damping effectively handle demanding conditions.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves in HVAC and chilled water systems prevent reverse flow, protecting pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. The compact design ensures efficiency and guards against backflow damage.
Q:What materials are available for customization?
A:
We offer customized material options including Ductile Iron, Cast Steel, and Stainless Steel to meet project-specific requirements in different regions.
