Flap Valve


The DFL model FCA flap type damper is designed for pneumatic transport applications and is used to isolate air or industrial gas in combustion and various process lines where temperatures may reach up to 900ºC. It consists of a cylinder shape body and a flap type gate.

When the flap comes in contact with the seat that is lodged in the gate, the valve will achieve full tightness.

The valve is provided with a flange type connection as per FCA Standard or according to customer’s requirements.
