Product Q&A

Q:How to select the right check valve for water supply and industrial pipeline systems?

For water supply and pipelines, swing or resilient seated check valves are recommended. Consider flow velocity, pressure rating (PN10/PN16), and installation orientation. For slow closure, choose slow-closing or damped valves to prevent water hammer.

Q:What makes check valves essential in fire protection and pump station systems?

Check valves prevent backflow and protect pumps from reverse rotation, closing automatically when forward flow stops. They ensure safety and pressure maintenance. 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?

Standard check valves operate automatically with flow direction. For systems with frequent flow changes, silent or spring-loaded check valves are ideal, closing swiftly and quietly to reduce 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?

Check valves are essential in HVAC and chilled water systems to prevent reverse flow and protect pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliability maintain system efficiency and safeguard components from backflow damage.

Q:What is the working temperature range of this valve?

The valve operates within a working temperature range of up to 80 degrees Celsius.
