Mental seat butterfly valve and resilient butterfly valve how to choose

Mental seat butterfly valve

Adopt metal sealing surface and other rigid materials to achieve zero leakage requirements, which can be used for medium high temperature, medium high pressure projects.

Its features:

1. the use of temperature can meet the requirements of high temperature (200℃+-);

2. high pressure, wear resistance, long service life

3. High cost. Compared with ventilated butterfly valve and soft seal butterfly valve, its cost is relatively high, and the configured actuator needs a larger model, resulting in a higher overall cost.

For environmental protection projects requiring zero leakage and slightly higher temperature and pressure, this kind of valve is a good choice, but cost control is unavoidable.

Resilient butterfly valve

The sealing surface is made of soft materials such as rubber fluorine rubber. When the valve is closed, the valve plate (metal material) and the sealing rubber (non-metal material) in the valve body are fully fitted to meet the requirements of zero leakage.

Its features:

1. widely used, can be used in water treatment projects, waste gas treatment projects;

2. In terms of temperature, due to the influence of the temperature resistance of the sealing material, the medium is used more in the project at normal temperature. The common sealing material is recommended to use temperature rubber (< 100℃), fluorine gum (<150℃);

3. Due to the influence of temperature and use time, the sealing material will slowly wear and age, so it is necessary to test and maintain the equipment regularly;

For projects requiring zero leakage, such as water treatment projects, this type of butterfly valve is a good choice, of course, choose to use but also meet many other requirements.
