Powder metallurgy plain bearings, specifically sintered bronze bushings, are a crucial component in the operation of butterfly valves, particularly those conforming to the DIN standard with a nominal diameter (DN) of A50. These bushings are manufactured through a sintering process, which involves compressing metal powders and then heating them to fuse the particles tog, creating a solid but porous metal structure.

The sintered bronze material offers several advantages for butterfly valve applications. Its porous structure allows for the infiltration of lubricants, providing self-lubricating properties that reduce friction and wear. This results in longer service life and reduced maintenance requirements for the valve.

In addition, sintered bronze bushings exhibit excellent mechanical properties, including high strength and durability. They can withstand the rigorous operating conditions of butterfly valves, including high pressures, temperatures, and frequent movement. The material's corrosion resistance also ensures reliable performance in various environments.

When selecting sintered bronze bushings for butterfly valves, it is important to consider the specific requirements of the application. The bushings must fit precisely into the valve housing to ensure proper alignment and sealing. The material should also be compatible with the lubricants and fluids used in the system.

Installation and maintenance of sintered bronze bushings for butterfly valves require careful attention. Proper installation ensures that the bushings are securely in place and aligned correctly. Regular maintenance, including lubrication and inspection, helps to extend the service life of the bushings and maintain the optimal performance of the valve.

In summary, sintered bronze bushings manufactured through powder metallurgy are an excellent choice for butterfly valves, particularly those with a DN A50 DIN specification. Their self-lubricating properties, high strength, and durability make them suitable for demanding applications. With proper installation and maintenance, these bushings can provide reliable and long-lasting performance for butterfly valves.

Powder Metallurgy Plain Bearing & Valve Bushings

VIIPLUS Metallurgy bearing is a bearing and made from metallurgy material. It is a mechanical component to permit constrained relative motion between two or more parts, especially linear or rotation movement.

The application of bearing with inserted graphite to large metallurgical crane.

VIIPLUS Bronze bearing materials have been affecting the metallurgical quality of early bearing failure of the main factors.

VIIPLUS bearings are widely used in valve,metallurgy, mining, petroleum, paper making, construction and other large machinery and equipment.

The development of self-lubricating composite bearing and trend of inlay material are introduced.

The VIIPLUS Company specializes in engine bearings, friction materials, sintered components and coatings.

All the valve's internal self-lubricating bearings are sliding bearings, the whole material the use of carbon steel liner.'

Because of its superior performance, the friction in friction application fields become best material, such as sleeve bearing, sliding bearing, the valve seat, seals, pump wear ring, etc.

According to the classify of the material, the using fields also can be divided to several parts:

1. Copper-based, used in ventilator, office machinery, starter, dynamoelectric tool and aero-transport;
2. Iron-based, used in the low-velocity and high-pressure environment;
3. Iron-copper-based, used in high-velocity and high pressure environment;
4. Iron-copper-pb-based, used in middle(high)-pressure and middle(high)-velocity environment, similar to the copper-based.
As the leader of self-lubricating bushing manufacturers in China, we recognize high quality, competitive price and best service as the crucial factors for a successful corporation. Here advanced technology, equipments and management system are widely adopted to ensure the soonest delivery and first-class quality.

Lubricant fitting is provided to permit stem bushing lubrication for ease of operation.

Valve Upper and lower bushings are standard for smooth valve operation.

The most common applications in valves are, for stem material in butterfly valves, and backseat bushings and wedges in cast steel valves.
