The 30 degree linear valve is produced in one-way and two-way types, the one-way 30 degree linear valve is used in the front part of the wall or the roof next to the side wall, and the two-way type is used in the ceiling away from the side walls. This type of air vent is suitable for a one-way model on the side wall up to a ceiling of 4 meters, and in order to maintain the beauty of the vent, the width of the vent 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. Also, in some cases, this type of valve is also used in the return air channeling system.

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 valued customers are produced from the best extruded aluminum fabric profiles with electrostatic 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 proportion to the length of the linear valve adds to its visual beauty.

The 30 degree linear valve, as its name suggests, passes the air passing through it by changing the angle of the air movement by 30 degrees. This model of linear valves has a suitable useful surface and low pressure drop. According to the vane profile used in 30 degree linear valves, different models can be produced such as 30 degree two-way linear valves.

Two-way 30 degree linear valves are generally used in the ceiling away from the side walls. Also, due to the low visibility inside the valve, this valve model is suitable for ceiling return air or installation 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.

Among the applications of this model, we can mention the use in spaces where a long throw length is required with a 30 degree angle change in the valve, including spaces where the required throw length is half 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.

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:

Installation of inspection valve is different from installation of these valves; The installation of the 30 degree two-way linear valve is done 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. 30 degree linear valve can be ordered with parallel and cross valve back dampers. This valve is produced in different types of furnace electrostatic powder colors. The default color of these valves is white electrostatic powder paint (RAL 9016) and upon request, it is possible to apply other colors by announcing the relevant color RAL. It should be noted that it is possible to provide the valve in an acid-washed form without any color coating.

Consumables and materials and thicknesses:

The material of the blade and frame profile in this valve is generally aluminum profile with a thickness of 1.25 mm for the blades and 1.25 mm for the frame.

The width of the valve frame can be 3.3 cm or 4.5 cm of aluminum profile or any other size of black or galvanized iron.

Dimensional limitations of construction:

The maximum length is 250 cm
The maximum width is 150 cm
The minimum length is 15 cm
The minimum width is 5 cm

Accessories:

Damper behind the valve made of galvanized sheet, parallel PD model
Damper behind the valve made of aluminum profile, 7 and 8 OD models
Automatic motorized channel damper, MOSQPDTV model

Final cover:

Color: 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 declaring the corresponding color resin. It should be noted that it is possible to provide the valve in an acid-washed form and without any color coating to the customer.

Anodized: These valves can be provided with anodized coating upon customer’s request.

Hot galvanized: It is not used for these valves.

Wood design cover: If requested by the customer, it is possible to provide wood design cover for these valves by sending a sample of the desired cover.

Installation requirements: Along with this valve, 4 screws related to installation are provided along with a screw nut to maintain the appearance of the valves. (Screws and screws are exclusively for valves produced by Shahrokhi Technical Institute.)
