A stainless steel ball valve is a type of shut-off and adjustable valve, the locking mechanism of which is a spherical plug in the form of a ball. The “seat” seal of the ball valve is a fluoroplastic seal. This seal is hermetically sealed and ensures smooth adjustment of the faucet handle. Depending on the environment and operating conditions, taps are made of different grades of steel, with different connection options.

Scope of application:

  • civil works
  • drinking pipelines
  • food industry
  • cryogenics
  • pharmaceutical industry (liquid transport)
By connection type Ball Valves stainless steel
AISI304L/316L are divided into:
  • BP/BP coupling ball valve (internal thread)
  • ball valve for welding (3 private faucet with welded pipes at the edges)
  • 3-way ball valve (L-shaped and T-shaped)
  • flanged ball valve

Hello, dear reader! Among the representatives of shut-off valves, the flanged ball valve stands out both for its appearance, and the way of joining communications. In today's article we will look at what design it is and how best to use it.

Flanged valves ball type differ from their analogues by the presence of flanges - round or less commonly found square parts, with the help of which the assembly body is attached to the mating flanges of the pipes.

The main function of fittings is to open or block flow through a pipeline.

Depending on the characteristics, material of manufacture and thickness of the housing walls, it can be installed in systems with contents that differ in their characteristics.

Purpose and scope

As shut-off valves, ball valves have practically replaced valves and gate valves from the market. By virtue of their design, they allow you to quickly shut down the work flow, including in certain sections of the network. This quality is in demand in emergency situations, when it is necessary to carry out local repairs and other cases.

A flange connection is used where it is difficult to use a threaded or welded connection.

For example, on pipes large diameter It is difficult to cut quality threads. Therefore, as a rule, flanged structures are installed in industrial and utility networks, in pipelines with a cross-section of more than 40 mm.

At home, flange connections are used for mixers and for laying water supply systems through submersible pumps.

Connection diagram for a submersible pump using a flange valve:


Characteristics

State standards standardize the main standard sizes and technical specifications device data. They are installed in a single size range, but have different restrictions, depending on the scope of application.

The main standard sizes include:

  • nominal inner diameter(DU), the range of which is allowed from 15 to 1400 mm;
  • construction length.

Technical parameters include:

  • the value of working pressure PN with different restrictions in individual GOSTs from 1 to 10 MPa, up to 250 MPa and above;
  • the operating temperature value or its relationship with the pressure indicator (determined by the manufacturer).

The applicability of cranes to various working environments is determined by the developers.

What materials are they made from?

The raw materials for the manufacture of the body and the shut-off part of the flange fittings are:

  1. cast iron;
  2. brass;
  3. carbon and alloy steel;
  4. stainless steel

On the picture steel crane stainless:

Crane device

The type of valve in question consists of a body with flanges, a locking mechanism located inside it, a manual control handle or other drive.

The locking device includes a polished ball, often chrome-plated or stainless steel, a rod secured through a spindle with a handle. A slot is made in the sphere, serving as a passage hole.

Principle of operation

When the handle is turned, the ball turns with a slot either towards the walls of the body (closed position) or towards the flow and opens its passage through the pipe.

Advantages and disadvantages

Let's look at the pros and cons of these cranes.

  • The main advantage of flanged devices is that the valve can be relatively easily dismantled without damaging the joints, repaired and put back in place.
  • Connections through flanges are considered the most reliable at high pressure working environment in system.
  • The crane can be mounted in both vertical and horizontal positions.

For ball valves flange type there are also disadvantages:

  • ball valves do not like impurities in the working environment, their sphere begins to wear out and leaks appear;
  • for everyday use they are quite expensive;
  • They are heavy, which creates additional load on the pipeline.

Differences between a faucet and a valve

Valves and gate valves were previously widespread. However ball design turned out to be more reliable, easier to manage and operate. Valves, for example, require constant maintenance, they often jam, and they are more massive.

Types and designs

Flanged ball valves are divided into types according to operating conditions and areas of application.

From the point of view of maintainability, housing designs can be:

  1. all-welded;
  2. two-part;
  3. three-part.

According to the degree of throughput, cranes are distinguished:

  1. full bore;
  2. standard bore.

The division by type of management is important:

  1. manual;
  2. with gearbox;
  3. electric drive;
  4. pneumatic drive;

Differences

Manual controls are standard.

Mechanical gearboxes are installed where smooth opening of the device is necessary, as well as on taps with a diameter of more than 30 cm.

Electric drives make it possible to control the device remotely and quickly adjust settings.

Pneumatic drives also allow you to control an object remotely, including in explosive areas where installing an electric drive is impossible.

Life time

The duration of stable operation of ball flange fittings is determined by the operating conditions and the material of its manufacture. Often the first seals to fail are those exposed to hot temperature network content. The mechanical part of stainless steel units can last up to 50 years, according to manufacturers.

The choice is determined by the composition of the working environment and the size of the communication pipes.

The most basic information about the crane is included in the device’s data sheet and is shown on the body markings.

approximate price

The cost of devices of this type depends on the standard sizes, technical characteristics And trademark products. A flanged valve with a diameter of 100 mm with a working pressure of 16 bar made of carbon steel, produced by a Russian manufacturer, can be purchased for an average of 3,500 rubles. A valve of the same size, but with a stainless steel stem and ball, a control function and a manufacturer from Finland will cost 49 thousand rubles.

Rules for installation and operation of the crane

Installers must be familiar with the installation rules recommended by the manufacturer.

Important to check before starting installation work completeness of the equipment, absence of any damage or defects.


When installing the tap, check the position of the valve - it should be in the open position.

During operation, the device is regularly inspected and checked for leaks. flange connections, cleanliness of the surface of the sphere and seals.

Do not use tools or levers that extend the handle to operate the crane.

Required tools and materials

To install a flanged manual valve you will need:

  • a set of keys;
  • ruler for checking alignment;
  • pipe cleaning tool;
  • the fittings themselves;
  • bolts and nuts for fastening.

If there are no counter flanges on the pipes, you will need welding equipment and flanged discs.

Work progress

  • Determine the installation location: it must be accessible for carrying out work on maintenance tap, and have room to turn the handle completely.
  • Pre-attached flanges

products for two bolts to the mating parts of the pipeline.

  • Check the alignment of the valve holes and pipes, and the alignment of the holes for the bolts in the flange disks.
  • Flange seals are placed.
  • Tighten the bolts crosswise with the appropriate force.

Features of operation

It is necessary to turn the valve handle until it stops, that is, the valve must be open or closed completely. Incomplete rotation of the handle can damage the sealing seats of the valve.

Depending on the design, the valve handle must be turned after a certain time to avoid the sphere jamming.

Frequent errors and problems during installation

Incorrect selection of fittings based on the type of working medium, its pressure and other important parameters.

Violation of installation rules: errors in the alignment of the tap and pipeline, misalignment of flanges during installation, which lead to tension and damage to the connection.

Installation of flanges with defects quickly leads to leaks.

When choosing equipment, it is necessary to provide a reserve for conditional pressure- the fittings must have a higher rating of this parameter, which is very important for the stable operation of the product in the future.

One of the disadvantages of flanged models is the weakening of fastening connections over time and, as a result, loss of tightness. Therefore, it is important to periodically tighten the bolts.
