Best 10 bottom valve Suppliers in the world 2025 - Blog

Introduction to Bottom Valves

Bottom valves are crucial components in fluid handling systems, typically installed at the bottom of a suction pipe in a tank or a well. Their primary function is to prevent the backflow of liquid when the pump stops operating, ensuring that the suction pipe remains primed. This not only saves time and energy during the next pump start - up but also protects the pump from damage due to dry running. Bottom valves are widely used in various industries such as water treatment, oil and gas, chemical processing, and agriculture.
