The opening degree of the gate valve refers to the degree to which the gate or valve is opened, usually expressed as a percentage of the opening degree. The determination of the opening degree needs to consider the following factors:

1. System requirements:

Determine the opening degree of the gate valve according to the needs of the system, such as the need to control the flow of liquid or air flow.

2. Gate valve type:

Different types of gate valves have different opening ranges, and the opening range needs to be determined according to the type of gate valves.

3. fluid properties:

The pressure, density, viscosity and other properties of the fluid will affect the opening degree of the gate valve, and the appropriate opening degree needs to be determined according to the nature of the fluid.

4. Environmental conditions:

Ambient temperature, humidity, vibration and other conditions will also affect the opening of the gate valve, it is necessary to consider the impact of environmental conditions on the gate valve.

5. Experience and skills of the operator:

The experience and skills of the operator have a certain impact on the opening degree of the gate valve, and it is necessary to ensure that the operator has relevant knowledge and skills.
