Product Description

Eccentric butterfly valve is a commonly used fluid control equipment, widely used in petroleum, chemical, electric power, water treatment and other industries. The following is the product introduction of eccentric butterfly valve:
1. Product Overview
The eccentric butterfly valve controls the on-off and flow rate of the fluid by rotating the butterfly plate. It is characterized by simple structure, small size, light weight, flexible operation, and is suitable for large-diameter pipelines. The eccentric design reduces the friction of the sealing surface and extends the service life of the valve.

2. Main types
- Single eccentric butterfly valve: There is an eccentric distance between the center of the valve stem and the center of the butterfly plate, which is suitable for low pressure and normal temperature occasions.
- Double eccentric butterfly valve: There are two eccentric distances between the center of the valve stem and the center of the butterfly plate, with better sealing performance, suitable for medium pressure and medium temperature occasions.
- Triple eccentric butterfly valve: There are three eccentric distances between the center of the valve stem, the center of the butterfly plate and the center of the sealing surface, with the best sealing performance, suitable for high pressure and high temperature occasions.

3. Structural features
- Valve body: usually made of cast iron, cast steel, stainless steel and other materials, corrosion-resistant and high-temperature resistant.
- Butterfly plate: disc-shaped, with various materials, which can be selected according to the medium.
- Valve stem: connects the actuator and the butterfly plate to transmit torque.
- Seal ring: Commonly used materials include rubber, polytetrafluoroethylene (PTFE), etc. to ensure sealing.

4. Advantages
- Easy to operat: 90-degree rotation can achieve switching, and the operating torque is small.
- Good sealing: eccentric design reduces friction and has excellent sealing performance.
- Long service life: Reduce wear and extend valve life.
- Wide range of application: can be used for water, steam, oil, gas and other media.

5. Application areas
- Petrochemical: used for the control of crude oil, natural gas and chemical media.
- Power industry: used for boiler feed water and cooling water systems.
- Water treatment: used for tap water and sewage treatment.
- Food and medicine: used in places with high hygiene requirements.
