Price formation factors for ball valves

Application area. The price of a shut-off steel ball valve depends on the area of ​​​​its application. The fittings that are used in residential buildings have a simpler design, so the cost of such products is low. Stopcocks used in the chemical, gas and oil industries have a sophisticated device to withstand pressure, temperature, corrosive liquids, etc. This equipment is offered at a higher cost.

Vexve ball valves- products of the Finnish company VEXVE OY, which today is one of the largest manufacturers of ball valves for pipelines. Due to the fact that the products of this company have proven themselves only from the best side, they are used not only in water supply and heating systems of the municipal industry, but also in industrial energy networks, in the food, petrochemical and oil refining, gas industries.

For almost fifty years, the company VEXVE OY has not only existed in Vammala, but has been successfully developing. During this time, the company has achieved great success: 200 thousand units of products are produced annually, which are exported to 20 countries around the world. Vexve ball valves represent the majority of these products and are the pride of the company. On the territory of the Russian Federation, the fittings of the enterprise could be purchased already 20 years ago. During this time, the company's engineers have improved Vexve ball valves, achieving the highest possible sealing and reliability. The product range includes valves with the possibility of installation by welding, as well as with coupling and flange connection. Preferably, valves have a nominal diameter ranging from 15 to 500 mm, since this is the most demanded pipe fittings.

Features of Vexve ball valves

The all-welded design of cranes provides a number of advantages. Firstly, the protection against leaks is significantly increased, since the body is a monolithic part in which the connection between the individual elements takes place at the physical and chemical level, and not mechanically. Secondly, due to the absence of fasteners, the weight of the reinforcement is reduced. Well, among other things, Vexve all-welded ball valves are more reliable than prefabricated ones in terms of protection against corrosion, coking with efflorescence and dirt. Stainless steel, which is the material for the production of these valves, resists corrosion, and at the same time has high fatigue strength, resistance to water hammer and thermal deformation. Not only the valve body is made of stainless steel, but also the valve stem and ball, unlike many other brands, where these structural parts are made of copper alloys.

The valves are equipped with polytetrafluoroethylene (PTFE) seals. In the people they are also commonly called Teflon seals, and in industry - fluoroplastic. These seals are able to withstand temperatures ranging from -269 to +260 °C. Moreover, PTFE seals are resistant to many aggressive chemicals such as alkalis, acids, solvents and oxidizers. Such sealing elements are tightly pressed against the ball by means of disk-type springs, thereby ensuring sealing both at low and at high pressure drops. The top sealing ring can be replaced without interrupting the flow of the medium, which significantly reduces the repair time.

Product testing is carried out in production in accordance with the European quality standard EN488:2003. In addition, all fittings produced by the enterprise are ISO 9001 and ISO 14001 certified. Product certification is carried out by the international agency Det Norske Veritas. Of course, in order to be able to be sold in Russia, Vexve ball valves have certificates of compliance with domestic standards and sanitary and hygienic conclusions, permission from the Gosgortekhnadzor of the Russian Federation.

Ball valves are a type of shut-off and control valves designed to shut off or regulate the flow of the working medium in various systems. The operation of such devices is based on the rotation of a steel ball having a through hole for passing the medium. At Build Engineering, you can purchase a Vexve ball valve for various purposes. The equipment manufactured by Vexve is made from the best materials and components in accordance with modern standards and can ensure the reliable operation of the system.

Ball Valves

Vexve ball valves are used to open/close the flow of coolant in a central heating system. This equipment has an all-welded design. Faucets are made of high-strength materials, allowing them to be used for water of any quality. A high quality ball seal and a special stem design with O-rings ensure high tightness. The compactness and light weight of the device make it easy to install.

Ball valves are characterized by low hydraulic resistance when the working medium is passed, which saves on pumping equipment. Due to their rounded shape, they are easy to isolate. They are easy to operate and require no maintenance. Vexve manufactures full bore and reduced bore valves with the following features:

• conditional pass: 10-800 mm;
• connection method: for welding, for threading, for flange.

This equipment can also be equipped with an electric or pneumatic drive.

Extended Stem Valves

Valves with an extended stem are used to shut off the medium flow of a central heating system in an underground installation. Vexve manufactures stainless steel reduced ball valves with the following features:

• conditional pass: 25-800 mm;
• connection method: for welding;
• stem length: 350 mm, 750 mm, 1000 mm, 1250 mm or on request;
• drive type: manual, hydraulic or electric.

The stem has a non-knockout design with two O-rings. The ball and stem are made of stainless steel, which increases the reliability and service life of the equipment. This shut-off valve has a small hydraulic resistance. The design of the device is completely sealed.

The ease of installation and operation of ball valves, along with their reliability, allows them to be used for the stable operation of various engineering systems.

Function of vexve ball valves

By individual order, they are equipped with manual gear drives, servo, pneumatic and electric drives. Specially by order for heating systems, valves are produced with an elongated spindle to bring the valve control element to the specified ground surface or height. Ball valves vexve, having an elongated stem, are made with cast thermal insulation and can be used in pipelines of heating networks and gas pipelines with channelless pipes in polyurethane foam insulation. In water supply systems, at industrial facilities and in thermal power engineering, high requirements are now placed on the indicators of operational reliability of devices and materials. Therefore, on the basis of regulatory requirements and requirements for operational reliability, the use of fittings made of non-ferrous metals, as well as ball fittings with coupling fastening to pipes, is limited. In pipelines with a diameter of more than 5 cm, operating in large pressure and temperature ranges, it is not advisable to use fittings made of non-ferrous metals. This is due to the fact that the strength indicators of the body of threaded fasteners of fittings made of non-ferrous metals are much lower compared to welded and flanged fittings made of steel and cast iron. But there are regulatory restrictions on cast iron fittings. Because of this, steel fittings for pipes belong to the main type used in heat and power facilities (central heating centers, thermal power plants, heating networks, boiler houses, thermal units) and in industry, including in pipelines of oil products and water supply networks, food and chemical industries.

vexve ball valves have the following features and benefits

- by means of an all-welded steel construction (fittings and body are welded together, steel DIN St /37.0/37.8), the device has a low weight and light insulation;
- ball and stem are made of stainless steel, ground and polished (stem - AISI 303, ball - AISI 304). This makes the faucet easy and reliable to use and reliable for a long time;
- Teflon seals (Teflon PTFE) loaded with belleville springs (resistant to wear, dirt and chemicals) make the ball perfectly sealed for various uses, at high or low pressure surges;
- the construction of the stem of the Veksve crane is not knock-out and has two O-rings made of FPM;
- the sealing outer ring is replaceable, and in models DN 65-300 mm both seals can be replaced;
- A PTFE Teflon sealing sleeve located between the stem body and the stem acts like a sealing surface. From the DN 65 version, the crane spindles are equipped with a stainless steel bearing bush;
- for DN 150-300 it is desirable to use a gearbox with a manual drive;
- the faucet handle is removable, for modification DN 10-150 it is made of galvanized steel, for DN 200-250 it is made of painted carbon steel. DN 300 does not have a handle.
Benefits of using and installing VEXVE cranes
