Overview
The linear flow control valve AFC is used to regulate the flow of fuel and cold air on various equipment. It regulates the control of Prida 25:1. It is equipped with our company’s AT31,AT50 and other actuators, which is suitable for remote flow regulation or stage control of combustion process.
Features
● There is a linear relationship between the regulating angle of AFC linear valve and gas flow rate.
● The adjustment range can be up to 25:1.
● Threaded linear valve can be used in all kinds of gas and room temperature air.
● It adopts automatic control mode and can be customized according to the needs of users
● Flanged linear valves can be used for cold or hot air.
Precautions for Installation and maintenance of AFC Linear Valve
● To ensure the normal and safe operation of the valve and a long service life, consider the following
recommendations when designing the combustion system:
●
Ensure that all functions of the system comply with valve specifications (gas type, working pressure, flow rate,
ambient temperature, voltage, etc.).
● According to the required installation position, it should be in the vertical position or tilted upward to the
horizontal position with the actuator, and shall not be inverted.
● In the case of vertical pipes, the flow direction should be from bottom to top.
● A fer removing the end cover, make sure that no foreign body enters the valve (such as chips or excessive
sealants) during handling or installation.
●A gas filter should always be installed upstream of the valve.
●It should be ensured that the installation area is protected from Rain Water and water splashing or falling
● Perform leak and functional tests after installation(maximum test pressure is 1.5 Pmax)
● For corrosive gases, maintenance must be carried out at least once a year
● It should be ensured that all work is carried out only by qualified technical personnel and complies with local
and national regulations.
● In order to prevent product damage and dangerous conditions please read the instructions provided with the
product carefully before installation.
● The maintenance cycle is once a year,and the number of maintenance is increased as appropriate.
