What valves are used for high temperature thermal medium oil heat transfer oil .

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Generally, cast steel valves such as gate valves, globe valves, etc. are metal hard seals.

There are two types of boiler heat transfer fluids. One is mineral oil, the base oil of mineral oil is a certain fraction cut from petroleum, which belongs to a hydrocarbon mixture. The second is synthetic oil, which is synthesized through chemical reactions, and the higher the purity, the better.

The application of heat transfer oil as an intermediate heat transfer medium in the process of industrial heat exchange has a history of more than 50 years. It is a once-through boiler developed based on the design idea of forced circulation. <

Choose the one that suits you according to the situation.

1. According to the medium temperature when the valve is working, it can be divided into:

1.Ordinary valves: valves for medium temperature -40 425.

2.High temperature valves: valves for medium temperatures 425 600.

3.Heat-resistant valves: suitable for valves with medium temperature above 600.

4.Cryogenic valves: suitable for valves with medium temperature -40 -150.

5.Ultra-low temperature valves: suitable for valves with medium temperature below -150.

Second, according to the nominal diameter of the valve can be divided:

1.Small diameter valve: valve with nominal diameter DN<40mm.

2.Medium diameter valve: nominal diameter DN50 300mm valve.

3.Large-diameter valves: valves with nominal diameter DN350 1200mm.

4.Extra-large diameter valve: nominal diameter DN 1400mm valve three, 1Low-pressure valves: valves with nominal pressure pn (including steel valves with pn) 2Medium pressure valve: A valve with nominal pressure.

3.High-pressure valve: A valve with nominal pressure.

4.Ultra-high pressure valve: a valve with nominal pressure pn.

Since the temperature of the heat transfer oil does not exceed 350 degrees at most.

Therefore, the selection should be selected, the temperature resistance can reach 350 degrees, such as cast steel material, the inside of the valve is metal seal, the rubber seal can only withstand temperature of 80 degrees, and the valve gasket can choose asbestos gasket or metal gasket.

It is best to use a globe valve or a gate valve, because the temperature is relatively high, and it is suitable for valves made of hard seal material.

Heat transfer oil should be a heavy-duty positive material gate valve.

According to the temperature of the medium, according to the temperature of the medium when the valve is working, it can be divided into: 1Ordinary valves:

Valves for medium temperatures -40 425. 2.High Temperature Valve:

Valves for medium temperatures up to 425 600. 3.Heat-resistant valves:

It is suitable for valves with medium temperature above 600. 4.Cryogenic valves:
