Egg basket valves, which are also known as checkered valves, are generally used on air discharge channels and in some cases on air return channels. The egg basket valve is produced in two models, round and square, and it is also possible to use both models inside the Armstrong tile.
These valves are produced in 0 and 45 degrees in terms of blade angle. Egg basket valves with a blade angle of zero degrees, the useful surface of the valve is more than the 45 degree type and the pressure drop is less than the 45 degree type. In 45 degree models, due to the vane angle, the visibility into the channel is lower than the zero degree type, and there is also the possibility of different arrangements of the vanes to direct the air flow.
Round egg basket valves are produced in standard sizes suitable for canals with diameters of 4, 6, 8, 10, 12, 14, 16, 18 and 20 inches. It exists. In square models, the size is customized and it is possible to install dampers behind parallel and opposite valves.
These valves are installed with self-tapping screws on a wooden frame installed on the edge of the channel, so it can be used on all types of walls such as plaster, cement, brick, wood, etc. This valve is produced in different types of electrostatic powder colors. The following are the features of these valves.
Installation location: wall or front of false ceiling or ceiling
Blade thickness: 0.8 mm
Material: Aluminum
Applications: return air and evacuation of different buildings
Frame thickness: 1 mm
Features: very low pressure drop for air discharge, air discharge control with damper, with straight and 45 degree vanes, one, two, three and four-way ventilation.
