Axial Flow Check Valves Guide: Non-Slam Closure, Water Hammer Control and Selection
Learn how axial flow check valves help reduce check valve slam, reverse flow, pressure surges, and water hammer risk in pump discharge lines, long-distance pipelines, water treatment systems, oil and gas pipelines, power plants, and industrial fluid systems. This guide explains axial disc movement, spring-assisted non-slam closure, low-pressure-drop flow paths, material selection, pump shutdown conditions, surge analysis, installation location, maintenance considerations, and key differences from swing check valves and dual plate check valves.
What is the Difference Between Butterfly Valve and Butterfly Check Valve?
Compare butterfly valves and butterfly check valves by operating function, disc movement, flow direction, installation, maintenance, and application. Butterfly valves are manually or automatically operated for pipeline isolation and throttling, while butterfly check valves operate automatically to allow one-way flow and prevent reverse flow in water, cooling, HVAC, chemical, and industrial piping systems.
