ball valve</h1

A ball valve is a type of valve that uses a spherical orifice plug (a rotating ball) to stop and start hydraulic flow.
A ball valve usually rotates 90 degrees (a quarter turn valve) on its axis to open and close.

It is one of the most widely used types of milk. Ball valves are suitable for both liquid and gas service.

They are very popular in the chemical, petrochemical and oil and gas industries due to their long life and reliable sealing throughout their useful life.

Ball valves can even be used for vacuum and refrigeration services.

Developed around 1936, ball valves are one of the least expensive valves available in a wide range of sizes.

Ball valves are sometimes used as control valves due to their cost-effectiveness, but are not preferred.

Because they do not provide precise control and settings.

The ball is placed inside the valve body and a handle or actuator is used to rotate the ball perpendicular or parallel to the direction of flow, thus controlling the flow of fluid.

When the hole is aligned with the direction of flow, the valve is in the open position, allowing fluid to pass through.
Conversely, turning the ball to block the hole closes the valve and stops the flow.

A ball valve is a quarter-round valve whose flow blocking member is in the form of a perforated sphere that rotates around a vertical axis relative to the direction of the fluid flow.

When the hole is aligned with the flow, the valve is open, and when the hole is perpendicular to the flow, the valve is closed.

Application of ball valves

Ball valves are used in a wide variety of applications including the following:

Plumbing: Ball valves are used to shut off and connect water flow in plumbing.

Industries: Ball valves are used to control fluid flow in industrial applications such as refineries, power plants, and chemical plants.

Installations: Ball valves are used to control the flow of water and gas in heating, ventilation and air conditioning systems.

Ball valves are used in a wide range of industries due to their versatility and ability to manage all types of fluids, from corrosive chemicals to high-pressure gases. The main applications of ball valves are:

Use of ball valves in refineries:

As shut-off and isolation valves for lower tower lines and thermal cracking units. Gas/oil separation lines, measuring stations, gas distribution pressure measurement and regulation, oil loading control stations, pumping and compressor stations, emergency shutdown loops, refining units, etc. are used.

Applications of ball valves in the electrical industry

It is used to control boiler feed water, such as burner shut-off valves, to control and turn off steam, etc.

Ball valves in gas and oil production

In subsea isolation and shutdown facilities, they are used for oil head isolation, pipeline fluctuation control, processing isolation, storage, transmission and distribution, secondary and enhanced oil recovery.

Water treatment

Municipal water treatment plants use ball valves to control water flow in various processes such as filtration, chlorination and distribution.

HVAC systems

Heating, ventilation and air conditioning systems use ball valves to regulate the flow of water and refrigerant in commercial and residential buildings.

Other applications of ball valves include:

Food industry
Sea and solid transportation
Water supply and transportation
Production

Ball valve standards

The following international codes and standards are used for ball valve design:

Design standard – API 6D / ISO 14313 / BS EN 17292/BS 5351/MSS SP 72
Test standard – API 6D / API 598 / BS 6755 Part I/MSS SP 61
Fire test standards – in accordance with API 6FA, API 607, ISO 10497 or BS 6755 Part II.
Dimensional standard – ASME B16.10 / API 6D

Advantages of ball valves

Simple Operation: Ball valves can be easily opened and closed by turning the valve handle 90 degrees.

High reliability: Ball valves have few moving parts, which makes them very reliable.

Good sealing: Ball valves provide a perfect seal when closed.

Easy installation: Ball valves can be easily installed in pipelines.

Types of ball valves

Ball valves are available in different types including the following:

Full metal ball valves: These valves are made of metals such as brass, cast iron or steel. They are suitable for high pressure and high temperature applications.

Plastic ball valves: These valves are made of plastic such as PVC or CPVC. They are suitable for low pressure and low temperature applications.

Butterfly Ball Valves: These valves have a disc that rotates to open and close the flow. They are suitable for applications that require fast flow.

The ball valve is a versatile and reliable valve that can be used in a wide range of applications.
