Product Q&A
Q:How to select the right check valve for water supply and industrial pipeline systems?
A:
For water supply, pump outlets, and industrial pipelines, swing check valves or resilient seated check valves are commonly recommended. Consider flow velocity, pressure rating (PN10/PN16), and installation orientation. For slow closure needs, opt for slow-closing or damped check valves.
Q:What makes check valves essential in fire protection and pump station systems?
A:
Check valves prevent backflow and protect pumps from reverse rotation in fire protection and pump stations. They close when forward flow stops, ensuring system safety and pressure. Resilient seated or double-door check valves offer reliable sealing and low pressure drop.
Q:Are check valves suitable for high-frequency flow changes and automated systems?
A:
Standard check valves automate based on flow direction. For frequent flow changes, silent or spring-loaded check valves are ideal, closing quickly to reduce 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 in HVAC and chilled water systems prevent reverse flow, protecting pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. Their compact design ensures system efficiency and shields sensitive components from 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.
