Check Valves

AGB Check Valves prevent reverse flow and protect pumps, compressors, and pipelines from damaging backflow surges. Available in dual-plate wafer, swing, tilting disc, and piston configurations, each design is optimized for low cracking pressure and rapid closure to minimize water hammer.

✓ Quick closing response minimizes water hammer
✓ Low cracking pressure for easy opening
✓ Maintenance-friendly renewable internals
✓ Multiple configurations: dual plate, swing, tilting disc, piston
