Product Description
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.
The dual-plate wafer design offers the most compact installation footprint, making it ideal for space-constrained applications. The swing check valve provides low pressure drop for high-flow systems, while the tilting disc design offers the fastest closure response for pump protection.
All AGB check valves are designed for maintenance-free operation with renewable internals for extended service life. Available in a wide range of materials for corrosive, cryogenic, and high-temperature services. Factory-tested to API 598 before shipment.
Quick Closing Response
Rapid disc closure minimizes water hammer and reverse flow damage to pumps.
Low Cracking Pressure
Optimized spring loading for low differential pressure opening.
Maintenance-Friendly
Renewable internals and top-entry access for in-line servicing.
Multiple Configurations
Dual plate, swing, tilting disc, and piston types for any application.
