Which Valve Is Superior: Butterfly Valve Or Lift Check Valve?

May 30, 2023 | News

Butterfly valves and check valves are commonly used in industrial settings to regulate the flow of fluids and gases. Butterfly valves are known for their cost-effectiveness and rapid operation, while lift check valves are often used to prevent backflow and protect downstream equipment. However, there are various types of butterfly valves and lift check valves available. As a China-based lift check valve manufacturer, we will provide you with more information about these valves.

More on Butterfly Valves

Butterfly valves are utilized to control the flow of liquids and gases. They consist of a disk or rotor connected to a central shaft, with the valve being fully closed when the disk is perpendicular to the flow and fully open when it is parallel.

High Performance Butterfly Valves

High performance butterfly valves (HPBVs) are designed for applications that demand high flow rates and precise control. They are usually made of materials that can tolerate high temperatures and pressures, making them suitable for use in harsh environments. HPBVs operate at a higher performance level than other types of butterfly valves due to their unique design. They have a disc that rotates 90 degrees to open or close the valve, providing a full flow path when fully open. Additionally, they have a high Cv value, indicating that they can deliver a high flow rate with minimal pressure drop.

Lift Check Valves – A Type Of Check Valve

Lift check valves, manufactured by China valves manufacturers, are designed to prevent backflow and protect downstream equipment from damage. These valves are typically installed in pipelines where backflow could cause serious problems, such as in pump discharge lines or in pipelines that transport hazardous materials. Lift check valves work by allowing flow in one direction, and then closing to prevent flow in the opposite direction. When the flow direction is reversed, the valve lifts from its seat and allows flow in the opposite direction. Lift check valves are typically made of materials that can withstand high pressures and temperatures.

How To Choose Right Valve For Your Application

When selecting a valve for your application, it is critical to consider several factors, including the type of fluid being regulated, the system’s temperature and pressure, and the required flow rate. Both butterfly valves and lift check valves have their unique advantages and disadvantages, and the right valve for your application will depend on your specific needs.
