Flanged Axial Flow Check Valve for Pump Discharge Protection

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

Check valves are vital in fire protection and pump stations, preventing backflow and protecting pumps from reverse rotation. They close automatically when forward flow stops, ensuring safety and maintaining pressure. Resilient seated or double-door check valves are favored for reliable sealing and low pressure drop.

Standard check valves operate automatically based on flow direction. For systems with frequent flow changes, silent or spring-loaded check valves are recommended for quick, quiet closing, reducing water hammer. High-quality designs with proper damping effectively handle demanding conditions.

Check valves in HVAC and chilled water systems prevent reverse flow, protecting pumps and chillers. They feature low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliable performance maintain system efficiency and protect sensitive components from backflow damage.
