What is the purpose of slow-acting valve controls?

Slow-acting valve controls serve an essential role in managing the flow of water, particularly in high-pressure systems. The primary purpose of these controls is to minimize the risk of water hammer, which is a phenomenon that occurs when there is a sudden change in the flow of water. When valves are opened or closed too quickly, it can generate a shock wave in the plumbing system, resulting in potentially damaging pressure surges.

By using slow-acting valves, operators can progressively increase or decrease flow rates, allowing for a more controlled transition that reduces sudden pressure changes. This controlled flow helps to protect the integrity of pipes and fittings, thus preventing catastrophic failures and costly damages. Therefore, focusing on the management of pressure and ensuring system longevity is a critical function of slow-acting valve controls in fluid delivery systems.
