Check valves permit flow in one direction only and protect systems from backflow. Selection balances the type (swing, lift, dual-plate, tilting-disc) against pressure, flow velocity, and space. Sizing to avoid chatter and confirming the cracking pressure are essential for reliable operation.
Q: What is a check valve used for?
A: Check valves prevent reverse flow in a pipeline, protecting pumps, compressors, and upstream equipment from backflow damage.
Q: Which standards govern check valves?
A: Common standards include API 594 (dual-plate and swing check), API 6D, and MSS SP-71.
Guidance reflects general engineering practice for check valves; confirm against the project specification and applicable standards before procurement.
