RF Type Butterfly Valve

RF type butterfly valve is a common industrial control valve, which is commonly used for fluid control, such as liquids, gases, etc. Flanged butterfly valves have a number of unique designs that provide very efficient fluid control and operation compared to other valves. The flanged butterfly valve is mainly composed of two main parts: the valve body and the valve disc. The valve body is a pipe section that is usually made of materials such as cast iron, stainless steel, and carbon steel, while the valve disc is a disc made up of a rudder-like structure, usually made of a high-strength material such as stainless steel or PTFE. The design of the flanged butterfly valve is very simple, but very flexible, so it is very convenient to use in piping systems. It is usually installed on a pipe through a flange connection and controls the flow and pressure of the fluid by operating a handle or an electric motor. At the same time, the kinetic energy involved in the operation of the butterfly valve is very small, so there is almost no waste of energy. In addition, flanged butterfly valves are extremely resistant to corrosion and high temperatures, making them widely used in the chemical, petroleum, pharmaceutical and food industries. In conclusion, as an efficient, economical and reliable control valve, the flanged butterfly valve plays a vital role in the modern industrial field.

Design criteria and features:

RF type butterfly valves are a commonly used type of valve with design features and benefits as follows:

1. Design features: Butterfly valve is a lightweight, short-structure valve, its structure is simple, composed of valve body, valve stem, gear, butterfly plate and other components. The butterfly plate is mounted at one end of the stem and is opened and closed by a geared stem.

2. Advantages: Butterfly valves have the following advantages:

(1) Small size, light weight, simple structure, easy to install and maintain.

(2) It is convenient to open and close, the fluid channel is smooth when opened, the flow resistance is small, the adjustment range is wide, and the flow control ability is strong.

(3) Good sealing, suitable for the control of gas, liquid, particles and other media.

(4) It has a long service life, can withstand harsh working conditions such as high temperature and high pressure, and has strong corrosion resistance and wear resistance.

(5) Electric, pneumatic and manual control modes are diverse, suitable for different working conditions.

To sum up, the butterfly valve connected by flange has the advantages of simple structure, convenient opening and closing, good sealing, long service life, etc., and is a widely used valve type in many industrial and construction fields.

Scope of application:

RF type butterfly valves are widely used in the control and regulation of industrial pipelines, including the following areas:

1. Chemical industry: petroleum, chemical, metallurgy, pigments, coatings, medicine, etc.

2. Environmental protection industry: water treatment, sewage treatment, air treatment, etc.

3. Food industry: food, wine, beverage manufacturing, etc.

4. Energy industry: electricity, nuclear energy, thermal power, wind energy, hydropower, etc.
