Uses Aluminum tailgate with the highest amount of air density, or in other words, the diffusion and transfer of inlet air in the intake manifolds. Ventilation systems. This valve is on the return and discharge route. Uses The aluminum round mesh valve is blown with the highest amount of air density, or more simply, the diffusion and transfer of inlet air in the intake manifolds of the ventilation systems.

Iron wall vents are made for the openings of canals that are installed in the walls of buildings. Wall valves consist of linear, lattice and one-way, two-way, three-way and four-way. Ordinary wall valve is made of three types of aluminum, iron and plastic, which has a damper and also without a damper.

The vertical blades also drive the wind to the armpit and the front blades to the front or downward. It is necessary to explain that the horizontal blades in front of the plastic valve play precisely the role of the damper and have the ability to change both air and air pressure and, if needed, block the air through the plastic valve path.

Flexible pipe or flexible hose pipe is a flexible metal form that is used to cover and protect network and power cables. These pipes are mainly used to protect cables in welding and industry. A shield or cover is used to prevent damage to the cable. The most important feature of these pipes is their flexibility. So it is resistant to any load or rotation. Therefore, at high pressures, long-term resistance to sunlight and high and low temperatures is very strong and durable and has a long useful life.
