DN100 Pilot Controlled Check Valve for Water Distribution Networks

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

Check valves are vital in fire protection and pump stations for preventing backflow and protecting pumps from reverse rotation. They auto-close when forward flow stops, ensuring system safety and pressure maintenance. 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 ideal as they close quickly and quietly, mitigating water hammer. High-quality designs with proper damping can handle demanding conditions well.

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