What material is used for the high temperature butterfly valve?

High-temperature cast iron butterfly valves can be used.

High-temperature wear-resistant is generally made of stainless steel and high-temperature treated.

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.

What is the actual temperature on your side? The data on your side gives you a detailed one.。。 The better I am here to choose the type and material for you.

This is based on factors such as the medium used by the valve, temperature, pressure, etc. Individual valves are basically wear-resistant, and hard-sealed rubber, etc., are relatively wear-resistant.

Sealing of butterfly valves.

There are nine kinds of materials:

x1 (natural food glue) zhi

DAOX2 (Hypalenne);

x3 (ethylene propylene monomer);

x4 (neoprene rubber);

x5 (nitrile rubber);

x6 (abrasion resistant rubber);

x7 (fluoroelastomer);

x8 (silicone rubber);

x9 (heat-resistant ethylene propylene rubber).

Butterfly valve, also known as flap valve, is a simple structure of the regulating valve, which can be used for the on-off control of low-pressure pipeline medium butterfly valve refers to the shut-off part (disc or butterfly plate) as a disc, rotating around the valve shaft to achieve opening and closing of a kind of valve, the valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting 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.

Nine types: x1 (natural food rubber), x2 (hypalen), x3 (ethylene propylene rubber), x4 (neoprene), x5 (nitrile rubber), x6 (wear-resistant rubber), x7 (fluoroelastomer), x8 (silicone rubber), x9 (heat-resistant ethylene propylene rubber).

9 types: H-stainless steel composite layer.

X3-EPDM version.

x4-chloroprene.

Rubber x5-nitrile rubber.

x6 (abrasion resistant rubber);

x7 (fluoroelastomer);

x8 (silicone rubber);

x9 (heat-resistant ethylene propylene rubber).

F-PTFE right.

What he said is not perfect, there are Teflon, and there are hard seals.

Stainless steel high-temperature butterfly valve. It can withstand high temperatures above 800 degrees.

Just add a layer of ceramic fiber products for thermal insulation.

Yes, but to use a butterfly valve that is resistant to high temperature and high pressure, the material requirements are relatively high.

Butterfly valves can be used in high-temperature occasions and can reach 800, but they are rarely used in high-pressure places, and generally will not be exceeded.

The high temperature and high pressure environment has high requirements for the material, and the butterfly valve is made of chromium-molybdenum steel, which can withstand high temperature to 850 degrees, and the maximum pressure is 64 kg at high pressure.

What kind of butterfly valve do you use, generally there are many ball valves at high temperatures.

The working temperature of the electric actuator does not allow such a high temperature environment, and the 1000 degree high temperature can not solve the problem by simply lengthening the valve stem and staying away from the heat source, and can be driven by a non-direct cross slider, and the low torque can be used to transmit torque by the slider with poor thermal conductivity such as non-metal, and the heat sink is appropriately added in the middle to achieve.

The two most used methods are currently available.

1 Lengthening the stem keeps the electric actuator away from high temperatures.

2. Add a heat sink between the electric actuator and the valve so that the high temperature cannot be conducted to the electric actuator.

This kind of valve belongs to the high-temperature valve, and there are usually more high-temperature butterfly valves. I see that the high-temperature valve or high-temperature butterfly valve made by Lei Li is made of stem extension and heat dissipation bracket, and there is basically no temperature to the actuator. There is no thermal conductivity temperature, but you should pay attention to the ambient temperature.

Lei Li does high temperature butterfly valves are still good, compared with other leading companies.

The ultra-high temperature butterfly valve selects suitable high-temperature resistant materials and unique structural forms, and the maximum operating temperature can reach 900 meters in the case of low pressure difference. Replacing the traditional water-cooled structure of the inner loop and the backward structure of lining refractory mud, this series of ultra-high temperature butterfly valves has simple structure, easy operation, large caliber and light weight. A non-face seal is used between the valve body and the valve plate.

The leakage is small, and it can be widely used in the industrial sector for automatic control or remote control of the production process.

High-temperature butterfly valves should generally not be burned with fire.

The high-temperature butterfly valve cannot be burned with fire, because the fire can be burned out at high temperature
