What is a sacrificial valve?

A sacrificial valve is a type of valve designed to protect more critical components in a system by allowing itself to wear out or fail first. It is typically made from materials that are less durable, ensuring that it absorbs the wear and tear from operational stresses. When the sacrificial valve fails, it can be easily replaced without significant impact on the overall system, thereby preventing damage to more expensive or essential parts. This approach is commonly used in various industrial applications, including water and gas systems.
