If you have a hard seal butterfly valve, you can come to our company to buy it!

Hello, happy to answer your questions. Welded ball valve and hard seal butterfly valve are two valves with very simple structure, but ball valves are more used in small diameters, and butterfly valves are mostly used in large-diameter pipelines. If it is under the condition of the same specification and the number of covers, the ball valve will be more expensive than the butterfly valve, including the volume and weight will be much larger.

However, because butterfly valve and ball valve are two completely different valves, and various uses are also different, so if you simply compare butterfly valve and ball valve, it is meaningless, and use the right valve in the right working environment to play its function and better serve us.

Abstract:The difference between hard seal butterfly valve and soft seal butterfly valve is mainly reflected in the structure, temperature resistance, pressure and sealing performance, among which in the temperature resistance comparison, the soft seal is used in the normal temperature environment, and the hard seal can be used in low temperature, room temperature, high temperature and other environments. Therefore, the scope of application of the hard seal butterfly valve is also relatively wide, and the scope of application includes furnaces, gas, steam, natural gas, city gas, hot and cold air, chemical smelting engineering and power generation environmental protection system, and the pipeline that transports various corrosive and non-corrosive fluid media.

Specifically, about the difference between hard seal butterfly valve and soft seal butterfly valve, and what is the scope of application of hard seal butterfly valve, let's take a look with me in the article! 1. The difference between a hard seal butterfly valve and a soft seal butterfly valve is in the first place.

If butterfly valves are divided according to the sealing form, they can be divided into metal hard seals and rubber soft seals. Let's take a look at the difference between hard seal butterfly valve and soft seal butterfly valve?

1. Structure: Soft seal butterfly valves are mostly centerline type hard seals, and most of them are single eccentric, double eccentric, and triple eccentric butterfly valves.

2. Temperature resistance: soft seal is used in normal temperature environment, hard seal can be used in low temperature, normal temperature, high temperature and other environments.

3. Pressure: soft seal low pressure-normal pressure, hard seal can also be applied to pneumatic soft seal butterfly valve under medium and high pressure conditions.

4. Sealing performance: soft sealing and triple eccentric hard seal butterfly valve have good sealing performance, and triple eccentric butterfly valve can maintain good sealing in the environment of high pressure and high slip temperature.

2. What is the scope of application of the hard seal butterfly valve?

The hard seal butterfly valve, also known as the flap valve, is a simple control valve, which can also be used for the on/off control of low-pressure pipeline media. The hard-sealed butterfly valve mainly plays the role of shut-off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting, so what is the scope of application of the hard seal butterfly valve?

The hard seal butterfly valve is suitable for the pipelines that transport various corrosive and non-corrosive fluid media in the furnace, gas, steam, natural gas, city gas, hot and cold air, chemical smelting engineering and power generation environmental protection systems, and is used to regulate and cut off the flow of the medium. The flammable hard seal butterfly valve is divided into manual hard seal butterfly valve, pneumatic hard seal butterfly valve, and electric hard seal butterfly valve.

There are many good manufacturers! There are many good factories in Jiangsu.

Zhejiang Chaoda and Antwei are professional manufacturers of hard sealing.

Suzhou Antwei Valve **** is a professional manufacturer of metal hard seal wear-resistant valves, covering an area of 30,000 square meters, plant 22,000 square meters

At present, the wear-resistant valves produced by Antwei have been widely used in petrochemical, coal chemical, silicon chemical, metallurgy, electric power and other industries, especially in the application of super harsh working conditions such as lock bucket valve, slag lock valve, high temperature valve, high pressure differential venting valve and silica powder valve.

This is the goods they just received yesterday. The packaging has been changed very well, the appearance is beautiful, and it should be relatively low in the whole market. Hope it helps.
