DN100 Slow Closing Non Return Valve for Pump Systems

For water supply, pump outlets, and industrial pipelines, swing or resilient seated check valves are typically recommended. Consider flow velocity, pressure rating (PN10/PN16), and installation orientation. For slow closure to prevent water hammer, choose slow-closing or damped check 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 system safety and maintaining pressure. Resilient seated or double-door check valves are favored due to reliable sealing and low pressure drop.

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

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 reliable performance maintain system efficiency and protect components from backflow damage.
