Краны шаровые

Snainless steel ball valves are varieties of cranes that are used in piping systems. The lockingelement has a spherical (ball) which has a through circular opening axially therethrough which is openwhen the faucet and the working medium passes. Tap hole diameter substantially the same as the innerdiameter of the conduit in this case is called a full bore valve. When the valve is closed fully hydraulic losses are negligible. It makes extensive use of stainless steel ball valves on gas pipelines in the food andchemical industry, namely where there is contact with aggressive liquids, gases, steam, hot water or sea water, oil, and other products with high pressure and temperature. Used for the manufacture of stainless steel grades AISI 316 (10H17Н13M2), AISI 321 (12X18H10T), AISI 304 (08H18Н10). Stainless steel ball valves do not corrode, and do not react with different working environment.

It should be noted these are the main advantages of ball valves:

leak tightness of a Class “A”, which is very high;
hydraulic losses are very small;
There are no dead zones;
simple design makes them durable and easy to operate;
quick turnaround;
able to apply in a viscous and contaminated environments;
high temperature limit of the working environment – from – 60 C to + 200 C;
high temperature limit of the environment – from – 60 C to +80 C.

CLASSIFICATION stainless ball valves

Depending on the passage, cranes may be: full flow and constricted.

Depending on traffic jams, ball valves are divided into: the rotation of the tube with a lift before the turn,and without lifting.

Depending on the shape of the passage, stainless ball valves can be: round, oval, rectangular, trapezoidal.

Depending on the material body, ball valves are divided into: titanium, plastic, brass, bronze, zinc, aluminum, steel, cast iron, ceramic, graphite, etc.

Depending on the material of the sealing surface cranes also come with plastic, graphite, metal, rubber seator nest.

Depending on the design of the hull ball valves are parallel, perpendicular or angled connectors, or one-piece body.

Depending on the actuator and the control valves can be manually operated or mechanized. In pipelines in ball valves are used as control environment that is transported by pipeline.

Depending on the direction of fluid flow ball valves are communicating, angular, multi-way, three-way.

Depending on the design of the locking bodies, cranes are divided into: valves with ball bearings and afloating ball.

Depending on the method of joining the line stainless ball valves are divided into: the coupling and nipple, flange, and welded.

Not a lot about each crane.

The coupling ball valves – designed to stop the flow of the medium, often water. They are called spherical, since the movable valve member has a spherical shape, which rotates around its axis and has a through hole.With PTFE end rings sealed space between the ball and the valve body. The coupling ball valves, stainless steel controlled by a lever actuator, gearbox. Typically, the valves are controlled by a lever, when the nominal diameter is less than DN125. If the diameter is larger, it is recommended to control the drive gear.With electric controlled valves where there is a place off control or shut-off valve is remote.

Stainless steel materials are often used in water, gas and steam supply systems, heating systems.

Cranes coupling are made of very light, high-quality, durable materials, thus differing durability andintegrity.

Nipple Ball Valves – is perhaps the most common cranes at the moment, and most commonly used in the petrochemical industry, power engineering, metallurgy, etc.

Nipple stainless steel ball valves have male threads on both sides, and attached to the pipe by means of coupling nuts and nipples.

Housing and locking parts are made with stainless steel faucet stainless steel, structural steel and othersteels. The main advantage of such cranes – is the ability to repeatedly install and dismantle them, as well asthe ability to operate in a temperature range from -60 to +200 ° C,

Flanged Ball Valves – used in the oil and gas industry in the trunk pipelines for transportation of natural gas, oil, and other chemicals, as well as in urban and municipal services.

The main advantages of stainless steel flanged ball valves – it’s a long life, low price, tightness, simple structure, no dead zones, the ability to install in any working position, easy steering control rod at 90 ° C,the possibility of applying for a very viscous and contaminated media, sludge and suspensions.

Welded ball valves – attached to the pipe by welding. They are used in heating systems and district heating.

The advantage of these cranes is that they have the full integrity of the compound as a fully steel body, andidentified for minimum maintenance. Shut-off ball cock inside made ​​of stainless steel, operational pressurePN 25 and the fluid temperature (water, steam, compressed air) is 0 … +150 ° C.

Our company offers a wide range of stainless steel ball valves, which are separated by the ambient temperature, pressure, flow rates, the method of connection, etc. We guarantee quality and reliability.STAINLESS STEEL BALL VALVES are varieties of cranes that are used in piping systems.
