How to choose a suitable Chinese valve model: China Valve Selection Guide

Chinese valves are integral components in fluid control systems, they are used to control, regulate and interrupt the flow of fluids. In order to ensure the safe, efficient and reliable operation of the system, it is essential to select the right Chinese valve. This article will detail the key factors and steps of valve selection in China to help you make an informed decision.

1. Chinese valve types

First, you need to determine the type of Chinese valve you want. Common Chinese valve types include gate valves, ball valves, butterfly valves, check valves, safety valves, etc. Each Chinese valve has its specific purpose and performance characteristics, so it needs to be selected according to the actual application scenario.

1. Gate valve: suitable for large diameter, high pressure difference applications, with good sealing performance.

2. Ball valve: simple structure, quick switch, suitable for frequent operation occasions.

3. Butterfly valve: compact structure, suitable for medium and low pressure, large diameter applications.

4. Check valve: prevent fluid backflow, suitable for unidirectional flow occasions.

5. Safety valve: When the system pressure exceeds the set value, the excess fluid is automatically discharged to protect the system safety.

Second, Chinese valve materials

The material of Chinese valves directly affects its performance and service life. Common Chinese valve materials include cast iron, carbon steel, stainless steel, copper, plastic and so on. When choosing Chinese valve materials, the following factors need to be considered:

1. Working media: Different media have different corrosivity to Chinese valve materials, and materials with good corrosion resistance need to be selected.

2. Working pressure and temperature: Chinese valves need to work normally within the specified working pressure and temperature range, so it is necessary to select materials with sufficient strength and temperature resistance.

3. Environmental conditions: Consider the environmental conditions of the Chinese valve, such as humidity, salt spray, etc., choose the appropriate material.

Three, China valve size

The correct selection of the Chinese valve size is essential to ensure the proper operation of the system. When determining the size of Chinese valves, the following factors need to be considered:

1 Flow: According to the actual flow requirements of the system, choose the appropriate diameter of the Chinese valve.

2. Pressure: According to the actual working pressure of the system, choose a Chinese valve with sufficient strength.

3. Temperature: According to the working temperature range of the system, select the appropriate temperature grade of the Chinese valve.

Fourth, the Chinese valve drive mode

The driving methods of Chinese valves are manual, pneumatic, electric, hydraulic and so on. When choosing the Chinese valve drive method, the following factors need to be considered:

1. Operation requirements: According to the operation frequency, remote control and other requirements, select the appropriate drive mode.

2. Safety: For flammable and explosive environment, explosion-proof drive mode should be selected.

3. Economy: considering equipment investment, operating costs and other factors, choose a cost-effective drive.

5. Brand and quality

Choosing well-known brands and high-quality Chinese valves can ensure the performance and service life of Chinese valves. In the purchase of Chinese valves, you can refer to the manufacturer’s technical parameters, quality assurance system, after-sales service and other aspects of information, comprehensive evaluation.
