The air volume control valve is also called the air control valve. It is an indispensable central air conditioning terminal accessory in the ventilation, air conditioning and air purification engineering of industrial plants and civil buildings. It is generally used in air conditioning and ventilation system pipes to adjust the air volume of branch pipes. HVAC control valves can also be used for the mixed adjustment of fresh air and return air.
The electric air valve is used as a gas medium to adjust the flow or cut off device in the dusty cold air or hot air gas pipelines of ventilation and environmental protection projects in the hardware, chemical, building materials, power stations, glass and other industries.
Analysis of the difference between the air volume control valve and the electric air valve:
The difference between the air volume control valve and the electric air valve is that the driving mode is different, and the control state is also different;
1. Electric air valve
The electric air valve is driven by electricity. The control method of the electric air valve can be divided into electric switch open quantity and electric analog quantity. The electric switch quantity has only two states of on and off, and the electric analog quantity can be adjusted between 0-100%;
2. Air volume control valve
The air volume control valve is the so-called manual air valve, and the control state can be adjusted between 0-100%, which requires manual operation.
