Different sealing structures of butterfly valves:

1. Soft sealing butterfly valve:

This seal structure type is perfect for butterfly valves that have both concentric and double eccentric structures. The pressure rating of these valves should not exceed CLASS 1500 for them to be suitable. In comparison, the centerline sealing structure is an excellent choice for valves that require a lower pressure rating of no more than CLASS150.

The valve body is equipped with a soft sealing ring that possesses the following characteristics:

A: Additional sealing rings or metal support rings are not necessary for the reliable sealing of it. Let me provide you with a highly similar content based on the original information.

B: It can maintain a two-way leak-free seal,

C: Less maintenance and long life.

The laminated metal-graphite sealing butterfly valve is a unique piece of equipment that is designed to effectively control the flow of fluids in a variety of industrial applications. This valve is constructed using a combination of laminated metal and graphite, which results in a durable and reliable sealing mechanism that is well-suited for use in high-pressure and high-temperature environments.

Unlike other types of butterfly valves, the laminated metal-graphite sealing butterfly valve offers superior performance and efficiency, thanks to its unique seal design. This valve operates by using a circular disc that rotates around a central axis, allowing for precise control over the flow of fluid. The laminated metal-graphite seal helps to prevent leaks and ensure that the valve maintains a tight and secure fit at all times.

Whether you are working in the chemical, pharmaceutical, or petroleum industry, the laminated metal-graphite sealing butterfly valve is an excellent choice for your fluid control needs. This valve is built to withstand even the most challenging conditions and is sure to provide you with reliable performance for years to come. So why wait? Invest in a laminated metal-graphite sealing butterfly valve today and experience the benefits for yourself!

The laminated metal-graphite sealing structure is specifically designed for use with triple eccentric butterfly valves that have a maximum pressure rating of CLASS 1500. This sealing structure is highly effective, as it is capable of preventing leakage in both directions. The laminated metal-graphite sealing material is typically made using a combination of stainless steel and non-metallic substances. The non-metallic materials used can include flexible graphite, PTFE and non-asbestos materials. The specific choice of material depends on the working conditions and the unique needs of the valve system. Overall, this sealing structure is a must-have for anyone looking to create a reliable, leak-free valve system.

3. Resilient sealing structure of elastic ring:

The metal sealing ring structure of our product is based on the J-type, making it ideal for use with butterfly valves incorporating a double eccentric design. It is suitable for pressure ratings of less than CLASS1500 and possesses a fireproof feature, making it ideal for use in environments with frequent temperature changes. Its exceptional sealing performance, extended life expectancy, and simplicity of manufacture make it an excellent addition to any application.
