Flanged Axial Check Valve with Internal Disc Guide

For water supply, pump outlets, and pipelines, swing or resilient seated check valves are recommended. Consider flow velocity, pressure rating (PN10/PN16), and orientation. For slow closure, 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 flow stops, ensuring safety and maintaining pressure. Resilient seated or double-door check valves are favored for their sealing reliability and low pressure drop.

Standard check valves operate automatically with flow direction. For 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 effectively handle demanding conditions.

Check valves in HVAC/chilled water systems prevent reverse flow, protecting pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. Compact design ensures efficiency, safeguarding components from backflow damage.
