Zero degree linear valve refers to valves with a blade angle of zero degree and in the form of narrow blades. This type of valve is used for both air supply and return air. The installation location of this valve is inside the wall and front of the false ceiling or in the ceiling. These valves are more shaped when their length is longer than their width, and it should be kept in mind that due to the linear distribution of air at a zero degree angle and the use of fixed vanes, it is not possible to move the vanes to adjust the air ejection in different directions.

The linear valves produced in Shahrokhi Technical Institute in various dimensions, frame and blade profile shape to cover the various tastes and aerodynamic needs of our valued customers are produced from the best extruded aluminum fabric profiles with electrostatic furnace paint. This air control valve model is 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 large lengths, as well as in the form of a soldier and two open ends 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). has it. 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 zero degree linear valve, as its name suggests, passes the air passing through it without changing the angle of the direction of air movement. For this reason, among linear valves, this model has the highest useful surface and the lowest pressure drop. Among the applications of this model, it can be mentioned that it can be used in spaces where a long throw length is required without changing the angle of the valve, including spaces where the required throw length is greater 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.

Installation of these valves is done by self-tapping screws and on a wooden frame installed on the edge of the channel, so it can be used on all types of roofs 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 furnace 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 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.

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 the plenum boxes, channel implementation errors and also the cost of channel implementation are reduced.

Linear valve installation:

The installation of the air distribution box and linear valve is very important; the installation of these valves is done with self-tapping screws and on a wooden frame installed on the edge of the channel, so it can be applied on all types of ceilings such as plaster, cement, brick, wood, etc. . 0 degree linear valve can be ordered with parallel and cross valve rear dampers. This valve is produced in different types of electrostatic powder colors.

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 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 coating:

Color: The default color of these valves is white electrostatic powder paint (RAL 9016), which can be applied in other colors upon request, by declaring the relevant color. It should be noted that it is also possible to offer the valve acid-washed 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.)
