Heated air dampers with rectangular section SVK-NS are intended for use in regions with cold climates. The purpose of the SVK-NS valves is to regulate the air flow rate or close the air ducts.

Structurally, the SVK-NS valve is a rectangular body, inside of which there are rotary louvers and, at each junction of the louvers, tubular electric heaters (TENs), designed to warm up the joints in case of possible icing of the valve and freezing of the louvers. Thus, the operability of the valve is ensured at an outdoor temperature of up to -60 ° C (moderate (U) and moderately cold climate (UHL) with placement category 2, 3, 4, 5 according to GOST 15150-69).
When designing an automation system, it is necessary to provide for the following operation algorithm in the winter period:

• before opening the valve, the heating elements are turned on for 10-15 minutes;
• after this time has elapsed, the valve drive is turned on with the subsequent disconnection of the heating elements.

SVK-NS valves are supplied with a universal platform for installing an electric or manual drive. The valve is equipped with a terminal box for connecting heating elements. The damper is mounted to the air duct using bolted connections. The valves remain functional and can be operated regardless of their spatial orientation.

Accessories
Electric drive, insulated casing for electric drive, manual drive.

The SVK-NS dampers of the Russian plant Arktos are intended for use in rectangular air ducts and are designed for regions with cold climates. The devices are installed in low pressure ventilation.

Design features and types of valves

The valve is made in a rectangular body, inside of which rotary louvers are installed. Tubular electric heaters are located at each junction of the blinds. In case of freezing of the blinds, they heat up the attachment points. As a result, the valve can perform its functions at temperatures down to -60 ° C.

The valves are produced in 24 standard sizes and are supplied in the following variants:

• SVK-NS - basic configuration without a drive. Has a universal platform for the drive and a terminal box for connecting heaters.
• SVK-NS + R - completed with a manual drive, a platform for the drive, a drive handle and a terminal box
• SVK-NS + electric drive - the set includes an electric drive in a warm casing.

Features of the operation of heated air valves:

• before opening the valve, it is necessary to turn on the electric heaters for 10-15 minutes
• after warming up, the electric heaters are turned off and the valve drive is turned on

SVK-NS valves of the following names are produced: 300x150U, 500x250U, 500x300U, 600x250U, 600x350U, 700x400U, 800x500U, 1000x500U

It is possible to buy valves with heating for rectangular air ducts SVK-NS from Arktos in Moscow in the A-clim company. On our website, a full range of devices with a detailed technical description and price is presented. We provide free delivery in Moscow.

This type of valve is the best option for regions with cold climates. The main purpose of the SVK-NS dampers is to close the air dampers or adjust the air flow rate.
Structurally, these valves represent a rectangular body, inside which rotary louvers are mounted. Each jalousie joint has tubular electric heaters, which are designed to warm up the joints in case of possible icing of the valve and freezing of the jalousie. In this way, the functioning of the valves is ensured at an air temperature of up to minus 60 degrees.
In the process of designing an automation system, it is necessary to provide for the following algorithm for working in winter:
1.before opening the valves, it is necessary to turn on the heating elements for ten to fifteen minutes;
2. then you can turn on the valve drive with disconnection of heating elements.
The SVK-NS valves are supplied with a universal platform for installing a manual or electric drive. The valve has a terminal box for connecting the heating elements. The valve is installed using bolted connections. The valves can function in any orientation in space.

Heated rectangular air dampers Arktos (SVK-NS) are designed to regulate the air flow rate or shut off the air ducts. Arktos SVK-NS dampers are designed for installation at the air intake or exhaust and have tubular electric heaters (TENs) at each junction of the rotary louvers for heating the joints in case of possible icing of the valve and freezing of the louvers. Heated air dampers are installed in low pressure ventilation systems (with differential pressures up to 1500 Pa). Body parts and louvers are made of galvanized sheet steel. All versions of the valves are equipped with louvers turning units made of materials that ensure the operation of the product at temperatures from -60 ° C to + 40 ° C (bushings are made of brass, axles are made of carbon steel with a zinc coating).

The standard-size range of Arktos heated air valves consists of 24 valves with the possibility of manufacturing each in the following versions: SVK-NS in the basic version is supplied without a drive (manual or electric), with a universal platform for a drive (manual or electric). In this case, a terminal box is installed on the valve for connecting the heating elements. SVK-NS + R with a manual drive is supplied with an installed platform for the drive and a drive handle. A terminal box with connection of heating elements is also installed. SVK-NS K + DRIVE TYPE is supplied complete with an electric drive installed in a heat-insulated casing. This ensures the operation of the electric drive at a minimum operating temperature of the valve up to - 60 ° C.

The casing is a box-shaped structure made of galvanized steel sheet, the inner walls are coated with thermal insulating material and a self-regulating heating cable is placed inside. Cable supply voltage 230 V, power consumption 40 W. A terminal box is installed on the air valve of the Arktos valve, in which the heating elements of the valve, the heating element of the valve drive, and the electric drive itself are switched. SVK-NS K is supplied only with an insulated casing without an electric drive. In this case, the type of drive is not indicated in the designation. The maximum height of the drive mounted in a heat-insulated casing is 85 mm. Manufacturing of air dampers with heating is possible with two body thicknesses of 160 and 220 mm; in the latter case, it is ensured that the louvers do not protrude beyond the dimensions of the damper.

Arktos dampers of standard sizes 1000x2400, 1400x1800, 1400x2400 are equipped with two actuators. It should be borne in mind that installing an electric drive on the valve (without additional drive insulation elements) reduces the lower limit of valve operation, which in this case is determined by the lower permissible operating temperature of the drive. When a manual drive is installed on the valve, the operating range remains the same - 60 ° C to + 40 ° C. By special order, it is possible to manufacture valves for other dimensions of the ventilation duct. The maximum valve height (dimension "B") is 2400 mm, the maximum valve length (dimension "A") is 2500 mm. It should be borne in mind that rectangular air dampers with dimensions on the "A" side over 1400 mm consist of two identical sections and are equipped with two actuators.

The heated air valve can be opened manually or remotely by means of an electric drive. The degree of protection of the product is IP44 in accordance with GOST 14254-96. For the correct operation of the SVK-NS air valve equipped with an electric drive, the control automation (in the control cabinet) must provide the following operation algorithm: before opening the valve, the heating elements are switched on for 20 minutes (the time interval is implemented by the automation); after 20 minutes, the valve drive is turned on, followed by turning off the heating elements. For an SVK-NS valve with an insulated casing of an electric drive, a permanent connection of the drive heating must be provided at an ambient temperature below -25 ° C.

Installation of SVK-NS Heated Rectangular Section Valve

Installation of the Arktos damper in the duct is carried out using bolted connections. Air duct sections at the places where the air damper is installed must be accessible for their maintenance and repair. Provide access to the actuator assembly when installing the valve. The valve remains operational regardless of the spatial orientation. For the electrical connection, a splash-proof terminal box is installed on the end face of the housing. Air dampers SVK-NS comply with the safety requirements of GOST 12.2.003-91. Protection class I in accordance with GOST 12.2.007.0-87. The air valve must be grounded in accordance with GOST 12.1.030.
