What is the recommended opening of the valve?

The recommended opening of industrial pipeline valves is determined based on the design requirements and operating parameters of the pipeline. For valves with the same characteristics, our recommended opening is generally between 50% and 70%, and cannot exceed 80%. For linear characteristic valves, the recommended opening is generally between 40% and 60%.

The recommended opening of a valve refers to the relative position between the open and closed states of the valve under specific circumstances. The relative opening and closing positions of the valve are determined by the fluid system designer based on actual conditions and needs. The recommended opening of the valve not only affects the flow characteristics of the fluid, but also affects the performance and stability of the valve. The recommended opening of the valve is very important in industrial production. Before determining the valve opening, it is necessary to select a suitable valve. Different types of valves have different characteristics and usage scenarios, and their prices also vary greatly. Therefore, the appropriate valve should be selected based on the actual situation encountered. In practical applications, the convenience and stability of valve operation are also very important. For valves that require frequent adjustment, valves that are easy to operate should be selected. Such as electric valves and pneumatic valves.

What are the factors that determine the recommended valve opening, and what are the setting principles?

There are many factors that determine the recommended valve opening. Let me share five points with you.
1. System pressure and flow requirements: According to the required pressure of the valve, select the appropriate valve and determine its relative opening and closing position.
2. Fluid characteristics: Consider the density, corrosivity, compressibility and viscosity of the valve fluid to select the appropriate valve type.
3. Pipeline resistance: Changes in the valve opening speed will affect the resistance in the pipeline, which in turn affects the pressure and fluid distribution of the entire valve system. Before determining the recommended opening of the valve, everyone needs to consider its impact on the resistance within the pipeline.
4. Safety factors: In some specific applications, the safety performance of valves is very important. For example, in the production of chemical plants, safety factors such as explosions and chemical leaks may be encountered, which requires the selection of valves with safety performance. Such as safety valves, explosion-proof valves, etc.
5. Economy: While meeting the valve performance requirements, economical valves and opening levels should be selected as much as possible, which can reduce the cost and maintenance costs of the valve system,carbon steel gate valves.

Recommended valve opening setting principles
1. Ensure the normal operation of the valve system: The opening and closing settings of the valve can ensure the normal operation of the valve system and meet the requirements and needs of factory production.
2. Do not over-adjust: The valve opening and closing degree should be adjusted appropriately and should not be adjusted too frequently. Unnecessary consumption of the valve system caused by frequent adjustments should be avoided.
3. Consider long-term operation: Before determining the recommended opening of the valve, the stability and reliability of the valve operation should be considered, and the valve should not be damaged due to frequent adjustments.
4. Parameters for optimizing performance: When the valve system is operating normally, the recommended opening setting of the valve should also consider its performance parameters, such as pressure, temperature, etc.

What are the precautions for practical application of recommended valve opening

1. In the thermal system, the outflow or stop of hot water is controlled by adjusting the opening and closing positions of the valve to meet different temperature and pressure requirements. Also be careful not to over-adjust the valve, which can result in heat loss and greater pressure loading on the valve.
2. In chemical plant production, regulating valves can control the pressure and temperature of chemicals according to the needs of chemical reactions. Pay attention to safety during the chemical production process and ensure that the valves used can withstand the corrosion and wear of chemicals.
3. In the water supply system, the switch of the regulating valve controls the water pressure and water flow, which can meet the water needs of different regions. During this process, attention should be paid to the occurrence of water coning and the impact of water flow on the pipeline.
4. During use, the wear degree and sealing performance of the valve should be checked frequently, and the valve should be maintained and replaced in time to ensure that the valve can work normally.
