Product Q&A

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

For water supply, pumps, and pipelines, use swing or resilient seated valves. Consider flow velocity, pressure (PN10/PN16), and orientation. For slow closure to prevent hammer, choose damped valves.

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

Check valves prevent backflow and protect pumps, closing automatically for safety and pressure maintenance. Resilient seated or double-door check valves are popular for reliable sealing.

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 close quickly and quietly, reducing 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?

Check valves are crucial in HVAC and chilled water systems to prevent reverse flow and protect equipment such as pumps and chillers. With low cracking pressure, tight shutoff, and minimal pressure loss when open, they ensure efficiency and safeguard components from backflow damage.
