Ball valves - view pipeline fittings, in which the shutter has the shape of a ball with a hole, in open position through which gas or liquid enters. Ball valves are a shut-off device; the movable moment of the valve has the shape of a body of rotation with a passage for the flow of the working medium; to shut it off, it rotates around its axis perpendicular to the axis of the pipeline. A manual or pneumatic drive used in a ball valve provides locking.

The main advantages and disadvantages of a ball valve over valves with valves include the following:

• low hydraulic resistance;
• simplicity of design;
• possibility of well-free installation on the pipeline and installation in any working position;
• small dimensions in height;
• absence of stagnant zones;
• simple shape of the flow part;
• full bore in ball valves;
• good protection and lubrication of sealing surfaces;
• simple operation (rotate the plug 90°);
• applicability for viscous or contaminated media, suspensions, slurries and slurries;
• possibility of use as a shut-off or regulating device;
• ball valves are more durable and reliable.

Ball valves are most often used for installation of plumbing and heating systems, water pipelines, and also recently they have become widespread in the assembly of gas pipelines.

The international classification divides ball valves into:

• Standard;
• Full bore;
• Partial bore.

The ball valve can have several options depending on the number of pipes and the direction of the working medium (through and angle valves, multi-way and three-way valves).

For the manufacture of ball valves, brass is used, stainless steel and cast iron. Ball valves are manufactured depending on where they will be used. Materials, coatings, designs depend only on the purpose of the crane.

Brass ball valves

Not much time has passed since the appearance of the brass ball valve, but it was immediately appreciated by the consumer. Brass ball valves can be classified as universal; they are used in plumbing, heating networks, and in the oil and gas industry.

The main advantages of brass taps include:

• Brass ball valves are used when transporting high-temperature working media;
• Using brass ball valves, you can instantly shut off the flow;
• Brass ball valves offer no resistance to flow;
• The closing of a brass tap cannot be prevented by mechanical impurities and deposits in the transported medium;
• The brass ball valve is not subject to corrosion;
• The ball valve body is made of brass using the hot pressing method. Brass cylinder heated in induction furnace up to 700°C in one working stroke the press acquires its final shape, this guarantees a homogeneous structure of the material in any section of the product, which, in turn, ensures the reliability of the product.

Steel ball valves

Ball valves are made of bronze, plastic, brass, ceramic, etc. Today, the leader among all valves of this type are steel ball valves. Took a leading place steel cranes due to high reliability and durability, great functionality, but at the same time their price is very low.

Steel ball valves are designed:

• for covering normal, aggressive and food environments;
• to block the flow of a liquid medium that is non-aggressive to the valve material;

The ball valve is indispensable for use in heat supply systems, in oil pipelines, in heating, cooling ventilation systems, in steam and condensate networks, in oil pipelines and other systems.

The main advantages of steel ball valves:

• Steel ball valves can be equipped with electric drives, pneumatic drives and worm gear reducers, and the drive mechanism is easy and simple to install even after the installation of the crane;
• Steel ball valves are made from super quality materials, have low weight and enormous reliability;
• It is possible to remove the faucet handle and move it 180°;
• During use, steel cranes do not require preventive maintenance. It does not need to be tightened or lubricated.
• The housing design does not have heavy and unreliable casting parts;
• Steel ball valves are reliable, durable and have high tightness.

Gas ball valves (GShK)

Gas taps balls are most often used in hot water pipelines, but design features expand the scope of their application.

Gas ball valves (GShV) are indispensable in industrial sectors such as petrochemical, chemical, gas and oil. Gas taps have a number of advantages over other types of shut-off valves, such as high strength, tightness, ease of use and long service life.

Gas ball valves have a number of important features:

• Replaceable sealing inserts in the valve allow you to quickly replace the seal;
• The lower drain hole makes it possible to clean the product without cutting out the pipeline, which greatly simplifies the process of cleaning the faucet.
• Thanks to the temperature compensator in the self-aligning wedge, you can easily control the temperature of the product.
• The cranes are environmentally friendly and comply with all SanPiN and state standards.

Gas valves are not used for regulation, since they have only two positions - fully open or closed. One of the important differences between gas ball valves and pipeline valves is strength.

Gas ball valves have several modifications, which differ according to the following principles:

• According to the diameter of the pipe being locked;
• According to the type of fastening of shut-off valves to the gas pipeline;
• According to technical data determined by pipeline safety requirements.

Gas ball valves differ in design during manufacture:

Climatic performance:

• Gas ball valves made of steel 20 GOST 1050-88 (from –40°C to +80°C).
• Gas ball valves “northern version - Nord” (an “N” is added to the designation). Crane made of steel 09G2S GOST 19281-89 (from –60°C to +80°C).

Design depending on the transported pipeline medium:

• Gas ball valves with fluoroplastic valve seal (F-4 GOST 10007-80) ("Zh" is added to the designation). The taps are designed to operate in the following types of environments: free of mechanical impurities, non-aggressive natural gas(GOST 5542-87), liquid phase of liquefied hydrocarbons (GOST 20448-90 and GOST 27578-87), petroleum products, water.
• Gas ball valves with polyurethane seal seal (SKU PFL 100 TU 38-1051240-78). Designed to operate in the following types of environments: non-aggressive natural gas, unrefined from mechanical impurities (GOST 5542-87), petroleum products, water.

Union ball valve

You can always buy a coupling ball valve from us:

• three-way coupling ball valve
• steel ball valve
• brass coupling ball valve
• stainless steel coupling ball valve

Stainless steel ball valve

Currently, stainless steel ball valves are used in all sectors of the economy: heat supply, food and chemical industry, in gas and oil pipelines and other pipeline networks, where switching, redirection and blocking of moving flows of the transported medium are needed (some models can also be used as valves). Most taps can withstand any aggressive environment - acidic, alkaline, hydrocarbon, etc.

Types of stainless steel ball valve:

• stainless steel three-way ball valve with with the following diagrams flow distribution: left - closed - right, left - right, left - on the flow - right;
• stainless steel wafer type ball valve;
• flanged collapsible (there are also solid cast ones);
• coupling;
• stainless steel welded dismountable ball valve (all-welded non-dismountable ones are available);
• welded deep (underground).

Possibility of control: manual, electric, pneumatic. The stainless steel ball valve has a wide range of diameters up to 200 mm and operating temperatures up to 180? C. Simplicity of design and reliability in operation allowed the stainless steel ball valve to become an indispensable link in any pipeline and a sought-after product.

Ball valve GShK wafer installed between the mating flanges of the pipeline using standard bolts. At the customer's request, it is possible to complete it with counter flanges and fasteners.

Reliability and tightness are especially important when transporting natural gas and safe use its consumer. The full bore cross-section of the valve valve ensures minimal aerodynamic and hydraulic resistance and does not interfere with the passage of pipeline cleaning devices.

Our ball valves do not require Maintenance or revisions throughout the service life.

GShK wafer-type ball valves are available in the following types:
