Bf Butterfly Valve

Bf Butterfly Valve

As a key equipment in the field of fluid control, BF butterfly valve plays an indispensable role in many industries with its unique design and excellent performance. It is mainly composed of valve body, butterfly plate, valve stem and drive device. The butterfly plate is like a disc, installed on the central axis of the valve body, and connected to the drive device through the valve stem. When the drive device is activated, it drives the valve stem to rotate, and then the butterfly plate makes a 90-degree rotation in the valve body, so as to realize the opening, closing and flow regulation functions of the valve.

The BF Butterfly Valve is an essential tool for regulating the flow of liquids and gases in various industrial applications. Its compact design, efficient flow regulation, and corrosion-resistant construction make it a reliable choice for industries ranging from water treatment and HVAC systems to oil and gas and chemical processing.

Advantages and features

  • Strong and durable materials: The valve body and butterfly plate are usually made of high-strength, corrosion-resistant materials. For example, the valve body may be made of stainless steel, nickel-plated iron, etc. These materials have excellent compressive strength and wear resistance, and can withstand the high-pressure impact and long-term friction of the fluid in the pipeline.

  • Easy and flexible operation: BF butterfly valves have a variety of drive devices, and can be selected according to actual needs. Manual drive is suitable for occasions with low operating frequency and relatively simple control requirements. The operator only needs to turn the valve stem through the handle to realize the opening and closing operation of the valve.

Order code Model DN Valve opening angle flow cv value
90° 70°
18240 DFR-01-800 800 68250 34395
18241 DFR-01-900 900 86375 39731
18242 DFR-01-1000 1000 119750 55084
18243 DFR-01-1050 1050 117500 70500
18244 DFR-01-1200 1200 154000 92300
Note: When the valve uses switch control, Cv is selected when it opens at 90°; when the valve uses analog control, Cv is selected when it opens at 70°. The recommended control angle is 25°~70°, and the optimal control angle is 60°~65°.

Applications

 

 

  • Urban water supply and drainage system: In the urban water supply system, it is widely used in water source intakes, water plant water distribution networks, and water supply pipelines at the user end. It can control the flow and pressure of water flow to ensure that urban residents and industrial enterprises can obtain stable and sufficient water.

  • Petrochemical industry: The petrochemical production process involves the transportation and treatment of a large amount of liquid and gaseous media. It plays an important role in crude oil extraction, refining, and chemical raw material production. It can be used to control the flow of various oil products, chemical raw materials, and corrosive media to ensure the safe and stable operation of the production process.

  • Power industry: It is also widely used in power facilities such as thermal power plants, hydropower stations, and nuclear power plants. In the cooling system of thermal power plants, butterfly valves are used to control the flow of circulating water to ensure the normal operation of generator sets.

FAQ

 

Q: How durable is it in high - pressure industrial pipelines?
A: It is extremely durable in high - pressure industrial pipelines. Constructed from high - strength materials like forged steel or ductile iron, it can withstand substantial pressure differentials without deformation or damage, ensuring long - term reliable operation in demanding industrial settings.


Q: What maintenance does it require regularly?
A: Regular maintenance for it mainly involves periodic inspection of the sealing elements. Check for any signs of wear or damage to the gasket.


Q: Can it handle abrasive fluids?
A: It can handle abrasive fluids to a certain extent. Equipped with wear - resistant coatings on the valve disc and seat, it can resist the erosive effects of abrasive particles in the fluid. However, the degree of resistance depends on the nature and concentration of the abrasives. For highly abrasive fluids, additional protective measures or specialized versions of the valve might be recommended.


Q: How accurately can it control the flow rate?
A: It can control the flow rate with a high degree of accuracy. The well - designed valve geometry and the precision of the closing mechanism allow for fine - tuned adjustments. By precisely regulating the opening area of the valve, it can achieve accurate flow control, which is crucial for maintaining consistent process conditions in industrial applications.
