A pressure surge can occur in a hydraulic system if you try to stop the flow in a pipeline to quickly. When a valve closes or a pump stops the water or oil or other fluid in a hydraulic system will attempt to continue flowing. This will cause an increase in pressure which can damage the pipe. Surge control devices absorb and limit this pressure increase and prevent damage to the pipework.
