The A- FOR pneumatic four-way valve is adapted to the regenerative combustion system, which simultaneously completes the three functions of organizing combustion, direction and flue gas emission through its periodic reversing operation. The A- FOR four-way valve is driven by compressed air, and the valve stem rotates 90 degrees to complete the dual air source four-channel switching. Under the condition of source pressure of 0.4-0.6Mpa, the commutation time is less than 5S.

A- FON is butterfly valve plus pneumatic pulse, suitable for cold combustion-supporting air at 200 ℃. Driven by the cylinder valve action, is the ideal device for regulating flow in the pipeline. A- FON butterfly valve is used in occasions with many intermittent operation times, flow regulation function and high switching frequency of large and small fires. The closing of the valve ensures a low leakage rate. It is necessary to provide compressed air 0.1-0.6MPa pressure to the cylinder, which is very practical in pulse control occasions. By adjusting the regulating valve of the cylinder, the speed of opening and closing the valve can be controlled to achieve pulse control.
