Air choke valve - Import export

The FDABURML coupling module is a combination of an air valve and a fire damper, coupled with a single housing. This is an alternative to typeical fire valves. The main advantages of the FDABURML are better fire rating and a smaller size with more product configurations and application options. The main component of the coupling module is the CFDM fire damper. The fire damper is available in Ø 100, 125, 160, and 200 mm. The wing blade of the damper provides a very low resistance to the air flow. The fire damper can be ordered with one or two optional limit switches to feed back the actual blade position. The FDABURML coupling modules match the most popular versions of air supply or exhaust valves which can be replaced with one another, even with the coupling module installed in a partition or already in use. The entire coupling module is compact. As a result, the air valves with the mounting frames cannot exceed 50 mm in height.

These valves have closure system in screen form by means of slide and connected to pipe lines and used for stopping fluid inside pipe. Screwed shaft which is mounted inside housing moves slide up and down and performs open and close operation for valve. Sealing is maintained by gasket which is coated over slide. They are used liquids which do not have abrasive property and in liquid fuel installations. They are not used for controlling and flow adjustment.
