Product Q&A
Q:How to select the right check valve for water supply and industrial systems?
A:
For water supply and industrial pipelines, choose swing or resilient seated check valves, considering flow velocity, pressure rating (PN10/PN16), and installation orientation. Use slow-closing or damped valves to prevent water hammer.
Q:Why are check valves crucial in fire protection and pump systems?
A:
Check valves prevent backflow, safeguarding pumps from reverse rotation. They auto-close when flow stops, ensuring safety and pressure maintenance. Resilient seated or double-door check valves are favored for reliable sealing and low pressure drop.
Q:Are check valves fit for high-frequency flow changes and automated systems?
A:
Standard check valves operate automatically with flow direction. For systems with frequent flow changes, opt for silent or spring-loaded check valves for quick, quiet closure, minimizing 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 are essential 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 ensures system efficiency and shields sensitive components from backflow damage.
