About Butterfly Valve

A butterfly valve, also known as a disc valve, is a simple regulating valve used for switch control in low-pressure pipelines. It consists of a disc that rotates around the valve axis for opening and closing. These valves are versatile, suitable for controlling various fluids like air, water, steam, and corrosive substances. They are commonly used for cutoff and throttling in pipelines.

Application Range

Butterfly valves find extensive application in industries such as petroleum, natural gas, chemical engineering, and water treatment, as well as in cooling water systems of thermal power plants. They are particularly suitable for large-diameter valves used in flow control.

Butterfly Valve

Turbine flanged triple eccentric butterfly valve

Turbine flanged triple eccentric butterfly valves are widely used for flow control in various industries. They handle temperatures up to 425°C and are made of materials like cast iron, cast steel, and stainless steel.

Pneumatic hard-seal butterfly valves

To address the contradiction between requiring high-temperature resistance with hard seals, which often result in significant leakage, and needing zero leakage with soft seals, which lack high-temperature resistance, a third eccentricity has been introduced to butterfly valves.
