The linear flow control valve AFC is used to regulate the flow of combustible and cold air on various equipment to ensure the stable and efficient operation of the burner. Its control ratio is up to 25:1, and it is suitable for remote flow regulation or stage control of the combustion process when equipped with an actuator.

Characteristic

1. The linear valve AFC adjustment Angle is in a linear relationship with the gas flow rate

2. High precision control, the adjustment range can reach 25:1

3. It can be used in various gases and ambient air

4. Tight sealing structure, low leakage rate and high control accuracy

5. High pressure and high temperature resistance, suitable for the high temperature and high pressure environment of burner

6. Automatic control mode is adopted, and customized configuration can be made according to user requirements

Operational principle

Thread linear drive: when the rotating valve stem is rotated, the thread structure converts the rotary motion into the linear movement of the valve core, so as to accurately adjust the flow rate.

Flow control: the change of valve core position directly changes the cross-sectional area of the flow channel, and realizes the stepless regulation of flow from fully open to fully closed.
