Centerline butterfly valves and how to choose a reliable supplier?
Butterfly valves are widely used in various industries to regulate the flow and cut off the medium in pipelines. They have the advantages of simple structure, small size, light weight, low cost, easy installation and maintenance. However, not all butterfly valves are suitable for every application. Depending on the design, material and sealing performance, different types of butterfly valves have different characteristics and limitations.
One of the most common types of butterfly valves is the centerline butterfly valve, which has a concentric design of the valve stem, the disc and the body. The disc is mounted on the valve stem and rotates 90 degrees to open or close the valve. The sealing ring is usually made of rubber or PTFE, which is embedded in the valve body or attached to the disc. When the valve is closed, the disc compresses the sealing ring and forms an elastic force to ensure the tightness.
Advantages of centerline butterfly valves
Centerline butterfly valves have several advantages over other types of butterfly valves, such as:
- They are easy to operate and have a fast opening and closing speed.
- They have a low flow resistance and a large flow coefficient.
- They have a good sealing performance and can achieve bidirectional sealing.
- They have a simple and compact structure and can be installed in any position.
- They have a wide range of applications and can be used for water, gas, oil, steam and other media.
- They have a low cost and are economical and practical.
Limitations of centerline butterfly valves
However, centerline butterfly valves also have some limitations that need to be considered before choosing them, such as:
- They are not suitable for high temperature and high pressure conditions, because the sealing ring may deform or deteriorate under high temperature or pressure.
- They are not suitable for corrosive or abrasive media, because the disc and the sealing ring may be damaged by corrosion or abrasion.
- They may have a large torque and a short service life due to the friction between the disc and the sealing ring.
