DN80 3 inch wafer Type IP65 Pneumatic UPVC Butterfly Valve with spring Single Acting pneumatic actuator

We are a professional manufacturer and supplier of pneumatic butterfly valves. Our factory independently develops and produces pneumatic butterfly valves, and the products are widely praised.

Advantages and characteristics

1. Simple structure, small size, light weight: compared with other types of valves, pneumatic butterfly valves have obvious advantages in volume and weight, easy to install and maintain.

2. Low cost, easy installation: The manufacturing cost of pneumatic butterfly valve is relatively low, and the installation process is simple and quick, reducing the cost of use.

3. easy to operate, fast response: pneumatic butterfly valve can achieve remote control and automatic control, improve production efficiency and product quality. At the same time, its response speed is fast, and it can quickly complete the switching and adjusting actions.

4. Suitable for high-viscosity and high-corrosive media: The disc of the pneumatic butterfly valve has compact structure, small fluid resistance, and can be applied to the flow control of high-viscosity and high-corrosive media.

Pneumatic wafer butterfly valve

Pneumatic wafer butterfly valve, butterfly valve equipped with pneumatic actuator. The execution speed of pneumatic actuators is relatively fast, and workers do not need to do it themselves, which saves human resources and time to a large extent. The butterfly disc of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc rotates around the axis, and the initial position of the valve is determined according to the actual demand, when the valve is rotated 90° from the initial position, it is the end of an action (from open to close, or from close to open), and conversely, it is the end of another action (from close to open, or from open to close).

Structure: Pneumatic wafer butterfly valve is mainly composed of valve body, valve disc, valve stem, pneumatic actuator, etc.

The valve body is usually made of ductile iron or stainless steel material, and the interior is precision machined to have good corrosion resistance.

The disc is the part of the butterfly valve, usually made of stainless steel or aluminum alloy, and the surface is polished to improve the flow performance.

The valve stem is connected with the valve disc and the pneumatic actuator, and the valve disc is opened and closed through the control of the pneumatic actuator.

                                       Technical parameter

As an important fluid control device, pneumatic flange butterfly valve is widely used in chemical, petroleum, metallurgy and other fields.

The pneumatic flange butterfly valve is composed of a body, a disc, a stem, a seat and a driving device.

Its most notable feature is the unique shape of the valve disc, similar to the shape of a butterfly, hence the name butterfly valve.

The disc of the butterfly valve can be freely rotated in the pipe, and the flow of the fluid can be adjusted by changing the rotation Angle.

In addition, the flange butterfly valve also has the characteristics of simple structure, light weight, easy installation, etc., which makes it widely used in the industrial field.

The working principle of the pneumatic flange butterfly valve can be simply divided into two steps: opening and closing.

When the valve is opened, the drive rotates the valve to an Angle through the air pressure, so that the fluid can pass smoothly.

When the valve is closed, the drive rotates the valve perpendicular to the pipe, preventing the passage of fluid.

Pneumatic butterfly valves are used in a wide range of industries, including but not limited to:

Petrochemical: Used for cutting off and regulating control of pipelines, storage tanks and reactors and other equipment, suitable for conveying various corrosive and non-corrosive fluid media, such as furnace gas, natural gas, liquefied petroleum gas and so on.

Manufacturing: It plays a role in fluid control systems, water supply systems, air conditioning systems and other equipment to achieve accurate control of fluid media.

Environmental protection: In environmental protection projects such as sewage treatment and waste gas treatment, pneumatic butterfly valves are used to control the fluid flow of the treatment system to ensure the normal operation of environmental protection equipment.

Energy field: In the power, oil, natural gas and other energy fields, pneumatic butterfly valves are used to control the transmission and distribution of energy media.

Water supply and drainage system: In the urban water supply and drainage system, the pneumatic butterfly valve is used to control the direction and flow of water flow to ensure the normal operation of urban water supply and drainage.

Marine engineering: In Marine engineering, pneumatic butterfly valves can be used to control various fluid medium pipelines of ships to ensure the normal operation of ships.
