DN100 Flanged Check Valve with Axial Guided Disc

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

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

Standard check valves operate automatically with flow direction. For frequent flow changes, silent or spring-loaded check valves, which close quickly and quietly, are ideal as they reduce water hammer. High-quality designs with proper damping effectively handle demanding conditions.

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