Check Valve
A check valve, also known as a one-way valve or non-return valve, is mainly used to prevent backflow of media, prevent reversal of pumps and drive motors, and achieve discharge of vessel media. Check valves can also be used in auxiliary systems for replenishing overpressure pipelines, and are generally installed on kill lines or kill lines requiring large flow rates.
