Danfoss butterfly valves. Danfoss Valve Danfoss Butterfly Valve Benefits

Danfoss shutter

Danish Danfoss valves are, perhaps, the most widely used and widespread not only in Europe but also in the world. Valves type Sylax produced by Danish giants in factories Socla in France, among them - the absolute leader. Characteristic feature that they can boast of Sylax valves is the way of their installation - they are all installed between the flanges connecting two sections of the pipeline. Fasteners of valves from Danfoss absolutely reliable - in addition to the saddle seal protruding beyond the body edges, the valve is equipped with lateral guides that allow the device to be precisely positioned between the flanges.

By by and large v Sylax valves all best ideas from the world's leading manufacturers of valves for pipelines.

Features and characteristics of Sylax ( Danfoss valves)

High-strength cast iron, which is not afraid of corrosion, sharp, in the range from minus 30 to plus 150 degrees, temperature changes and mechanical influences, is selected as a material for the body and disk, which completely or partially - in most models - covers the current of the working medium.

The rod on which the models Sylax the swivel disc is attached, spring-loaded with two bearings. As a result, the slewing mechanism becomes better controllable and is not subject to vibration.

A novelty in the opening and closing mechanism is a design developed for Sylax, which allows the disc to float along the horizontal axis of the valve. As a result, the reliability of the mechanism has increased, and the ability to accurately regulate the flow of the working medium has greatly increased.

Danfoss shutter today it is considered one of the most reliable in terms of tightness. In it, as in some valves, there is a special circular deepening channel. But if the channel is evil for valves, then Sylax shutter"Uses" it for lining - and this is a guarantee of one hundred percent tightness with a complete shutdown of the pipeline.

Finally, the Sylax models are heat-resistant. Heat resistance is achieved due to the use of a special durable polymer for the seat seal, which can withstand temperatures of up to 130 degrees for a long time.

The Vorder company is the official dealer of the Danish company Danfoss, specializing in the production of pipeline valves. The manufacturer has been working in this direction since 1933 and by now has won an excellent reputation, both among private buyers and in the professional environment.

Note! Direct cooperation with the Danish plant allows us to maintain optimal prices for all brand products, and also makes it possible to guarantee the original origin of the fittings. It should be noted that there is a wide range of devices, thanks to which each user will be able to purchase the necessary products. For example, on this page you can buy a butterfly valve with a cast iron or steel disc. The range of fittings includes 20 models, the nominal diameter of which varies from 25 to 350 mm.

Benefits of Danfoss Butterfly Valves

Pipe fittings of this brand are widely used in household and industrial air conditioning, heating, and water supply systems. Moreover, it can act as a working environment as hot and cold water and other liquids, for example, glycol solutions. In this case, the maximum temperature in the system can reach 120 ºС, and the pressure varies from 10 to 16 bar. However, the advantages of the devices are not limited to this. A separate word is deserved by such advantages as:

    double seal for maximum tightness;

    high maintainability due to the interchangeability of parts;

    reliable fixation of the stem with a spring ring;

    lack of contact between the housing and the working medium, thereby preventing corrosion and extending the service life of the device.

And in addition, it is worth noting the relatively low cost, which is explained by the loyal pricing policy of the manufacturer, as well as direct supplies of fittings to the warehouse of the Vorder company. By using the services of our online store, you can really inexpensively purchase a steel or cast iron butterfly valve.

Danfoss butterfly valves are used for cutting off or regulating the flow of the working medium in heating, hot and cold water supply, air conditioning and ventilation systems, as well as in various installations of the chemical, pharmaceutical and food industries. As a shut-off element in these devices, a disc is used, when turned, the shutter is opened or closed. In the Build Engineering online store, you can buy butterfly valves from a trusted manufacturer of engineering equipment. Valves of the VFY and SYLAX brands are available for sale at an affordable price.

Characteristics of Danfoss butterfly valves

Equipment manufactured by Danfoss has the following characteristics:

  • nominal diameter: 25-350 mm (VFY, SYLAX), 400-1200 mm (SYLAX);
  • maximum pressure: 10, 16 atmospheres (VFY, SYLAX);
  • permissible medium temperature: -15 ... + 120 ° С (VFY, SYLAX).

Butterfly valves are mounted on the pipeline between conventional counter flanges without the use of additional gaskets, since their role is played by the seat seal. Models are available with centering lugs, double flanges and threaded lugs. Valves with threaded lugs and double flanges can be installed at the end of a pipeline.

The following types of control are used to actuate the gates:

  • manual (metal handle, gear drive);
  • mechanical (pneumatic drive, electric drive).

Butterfly valve features

All parts of these devices are interchangeable, including axles, discs and seat seals, which reduces maintenance costs. The stem is double sealed to ensure high tightness. Anti-friction bearings reduce torques and increase equipment life. The splined disc-to-stem connection provides reliable torque transmission and less wear than other types of connections. The self-centering disc guarantees a high degree of tightness and reduces seat wear.

Availability various materials seat seal and disc allows this equipment to be used for a variety of media. The easily disassembled system ensures easy maintenance.

From us you can purchase reliable pipeline fittings at an acceptable cost with delivery in Moscow and the regions of the Russian Federation.
