The 15 degree linear valve is produced in three types: one-way, two-way, and full sugar head. 15 degree one-way linear vents are generally related to the distribution of exhaust air in the front part of the wall and at a not very high height (below 3 meters) or parts of the wall front that are hidden in the roof structure are used. Two-way 15 degree linear valves are generally used on the roof to distribute outgoing air with a relatively high height (about 4 meters). Also, the 15 degree linear valve model with a full sugar head is suitable for ceiling return air or installation inside the ventilation valve of the fan. It is a coil.
The linear valves produced in Shahrokhi Technical Institute in various frame sizes and vane profile shapes to cover all kinds of tastes and aerodynamic needs of our dear customers are produced from the best extruded aluminum fabric profiles along with electro-static furnace paint. These air regulating valves are used for various applications. Linear vents can be used in exhaust or suction (air exhaust or return), on the wall or ceiling, and even on the corner of the walls. Due to the stability of the vanes of these valves, it is possible to produce them in long lengths as well as in the form of a soldier and two open heads to be placed together in cases where the required length of the valve is greater than the maximum length that can be produced (two and a half meters). By using these capabilities, all kinds of architectural needs can be solved. It is worth mentioning that choosing a low height in relation to the length of the linear valve adds to the visual beauty of this.
The 15 degree linear valve, as its name suggests, passes the air passing through it by changing the angle of the air movement by 15 degrees. This model of linear valves has a suitable useful surface and low pressure drop. According to the vane profile used in 15 degree linear valves, different models can be produced such as 15 degree two-way linear valves and full sugar head linear valves.
Two-way 15-degree linear valves are generally used on the roof to distribute outgoing air with a relatively high height (about 4 meters). Also, the 15-degree linear valve model with a full sugar head is suitable for ceiling return air due to having the least visibility inside the valve. Or it is installed inside the inspection valve under the fan coil. In addition, with different combinations of vertical and horizontal rows of these blades, various distribution patterns such as three-sided and four-sided, etc. can also be produced.
The applications of this model can be used in spaces where a long throw length with a small angle change in the valve is required, including spaces where the required throw length is slightly more than the height of the ceiling. It is worth mentioning that, if needed, the vanes of this model of linear valves can be assembled and operated vertically.
These valves are installed with self-tapping screws and on a wooden frame installed on the edge of the channel, so it can be used on all types of ceilings such as plaster, cement, brick, wood, etc. The zero degree linear valve can be ordered with parallel and reciprocal valve back dampers. This valve is produced in different types of electrostatic powder colors. The default color of these valves is white electrostatic powder paint (RAL 9016). In case of request, it is possible to apply other colors by announcing the corresponding color resin. It should be noted that it is possible to provide the valve in an acid-washed form without any color coating.
In order to increase the pressure behind the linear and homogeneous valve and to make the output flow uniform along the length of the valve, plenum boxes can be used, which are offered to our dear customers both assembled and non-assembled. In addition, by using the connection of flexible channels between the main channel and plenum boxes, errors of channel implementation and also the cost of channel implementation are reduced.
Linear valve installation:
In order to maintain beauty, the width of the valve should be greater than its height. It should be noted that the vanes of this valve model are fixed and there is no ability to move the vane to adjust the air ejection in different directions. These valves are installed with self-tapping screws on a wooden frame installed on the edge of the canal, so it can be applied on all types of roofs such as plaster, cement, brick, wood, etc. 15 degree linear valve can be ordered with parallel and opposite valve back dampers. This valve is produced in different types of electrostatic powder colors.
