Main Features and Benefits

1. Material Strength and Corrosion Resistance:

Stainless steel is known for its excellent strength and corrosion resistance, which enables stainless steel flange butterfly valves to maintain long-term reliable operation in environments exposed to harsh chemicals, high pressure or extreme temperatures. Its durability allows the valve to have a long service life even in demanding environments.

2. Compact structure and light weight:

Butterfly valves have a more compact design and lighter weight than other types of valves (such as gate valves or ball valves). This design advantage simplifies the installation process and reduces the need for structural support, which is particularly beneficial in large-scale industrial applications.

3. Easy installation and maintenance:

The flange connection method facilitates the installation and removal of the valve, thereby simplifying the maintenance and replacement process, reducing downtime, and reducing operating costs.

4. Wide range of applications:

Stainless steel flange butterfly valves are suitable for a variety of media, including liquids, gases and slurries. Its excellent sealing performance makes it suitable for switch control and throttling applications.

5. Efficient flow control:

The disc of the butterfly valve rotates around its own axis to open and close. It has a simple structure and fast operation, which is very suitable for applications that require rapid closure.

Main components of stainless steel flange butterfly valve

1. Valve body:

The valve body is made of stainless steel, providing a strong and durable shell for internal components. The flange design ensures a tight and leak-free connection between the valve and the pipeline flange.

2. Valve plate:

The valve plate is also made of stainless steel and is the core component for regulating flow. When the valve plate is parallel to the direction of the fluid, the valve is in the open state; when it is vertical, the valve is closed.

3. Valve seat:

The valve seat is usually made of elastic materials such as EPDM, PTFE or Viton, providing a tight seal between the valve plate and the valve body, thereby preventing the valve from leaking when closed.

4. Valve stem:

The valve stem connects the valve plate to the actuator or handle, transmitting the rotational motion required for operation to the valve plate. The stainless steel valve stem has excellent strength to prevent bending or breaking under stress.

5. Actuator/Handle:

The butterfly valve can be operated manually by a handle or automatically by a pneumatic, electric or hydraulic actuator. This flexibility enables it to be integrated into automated systems for remote or precise control.

Applications of Stainless Steel Flange Butterfly Valves

- Water treatment: Used to regulate flow and isolate sections of water pipes.

- Chemical processing: Suitable for handling a variety of corrosive chemicals due to its corrosion resistance.

- Oil and gas: Used to control pipeline systems for fluids such as crude oil and gas.

- Food and beverage: Excellent in applications that require high hygiene standards and easy cleaning.

Conclusion

Stainless steel flange butterfly valves are the preferred choice in many industrial applications due to their durability, corrosion resistance and efficient flow control capabilities. Their simple design and easy maintenance make them a cost-effective solution for both high-performance applications and standard applications. Whether in water treatment, chemical or oil and gas industries, these valves provide reliable service with minimal maintenance requirements and are an important part of modern piping systems.
