Flange Butterfly Valve

ZhongGuan Valve is a senior supplier for many inventory vendors and distributors in  many different countries .Flange Butterfly Valve body: It is usually made of materials such as cast steel, cast iron, stainless steel, etc., which have strong corrosion resistance and durability.

Butterfly plate: It is the core component of the valve, usually made of materials such as stainless steel and aluminum alloy, ensuring the portability and efficiency of the valve.

Seals: Rubber, PTFE and other materials are usually used, which have good sealing performance and can effectively prevent leakage.

Drive device: Butterfly valves can be driven manually, electrically, or pneumatically, and different drive methods are suitable for different working environments.

Application

Flange Butterfly Valves are widely used in various industrial fields, especially in pipeline systems that require fluid regulation and cutoff. Specific applications include:

Chemical industry: used for controlling fluids such as acid-base solutions and chemical gases.

Oil and natural gas: used for fluid regulation in oil and gas pipelines.

Water treatment: used for fluid control in water plants and sewage treatment plants.

Fire protection system: used for water flow control in fire pipeline systems.

Food and Beverage: Used for fluid control in food and beverage production, especially in situations with high hygiene requirements. 

Working principle

The core component of aFlange Butterfly Valve is a disc-shaped valve plate, which is connected to the valve stem through a shaft. The rotation of the valve plate determines the opening and closing of the valve. Valve plates are usually made of materials such as cast iron, aluminum alloy, stainless steel, etc. When the valve is opened, the angle of the valve plate is parallel to the direction of fluid flow, allowing fluid to circulate; When the valve is closed, the valve plate is perpendicular to the direction of fluid flow, blocking the fluid.corrosive media.

Lifecycle Cost Efficiency

Modular construction reduces maintenance duration by 60% and parts replacement cost by 50%, achieving MTBF ≥50,000 cycles.
