Ball valves for flow regulation of media

Ball valves are an essential component in many different industries and applications. These valves are designed to regulate the flow of liquids or gases by opening or closing a ball-shaped door inside the valve. Ball valves are known for their reliability and durability, making them a popular choice in both commercial and industrial applications.

One of the advantages of ball valves is their ability to handle high pressure and high temperatures without being damaged. This makes them suitable for use in processes where high levels of precision and reliability are required. Ball valves are also very versatile and can be used to regulate the flow of a variety of liquids and gases, including:

  • Water
  • Oil
  • gas
  • Chemicals

At Alfotech we offer a wide range of ball valves in different sizes and variants. Our ball valves are always supplied in stainless steel, which ensures a long service life, durability, and high corrosion resistance. These properties are particularly important in many industrial applications.

Differences between 2-part, 3-part and 3-way ball valves

2-part ball valves consist of two parts that can be separated when the valve needs to be cleaned or repaired. These valves are simpler in design and may be suitable for simple applications with lower reliability and flexibility requirements.

3-part ball valves consist of three parts and are designed for easy disassembly, cleaning, and maintenance. They are suitable for applications where flexibility and configurability are needed.

3-way ball valves have three connection ports and can direct the flow between three different pipelines or systems. They can be operated manually or automatically and are suitable for applications where there is a need to direct the flow between different pipelines or systems, such as in dosing or flow regulation.

Benefits of ball valves

Ball valves have many benefits in various applications, including in food processing, pharmaceutical production, and the chemical industry. Here are some of the most significant ones:

  • High flow and low pressure drop: Ball valves have a large orifice diameter and a streamlined passage that creates a direct path. This results in a high flow capacity with minimal pressure drop. This is particularly important in applications where there is a need to transport large volumes of liquids or gases with minimal resistance.
  • Durability: Our ball valves are constructed from durable stainless steel, which makes them resistant to corrosion and wear, making them suitable for use in aggressive environments or applications with high pressure and temperature.
  • Easy to operate: Ball valves are usually easy to operate and do not require much torque to open or close. This makes them a good choice when frequent operation is needed or when you want to automate the operation with an actuator.
  • Good sealing: Ball valves are known to have an effective seal when closed. This is due to the ball valve pressing a ball against the seat to create a secure seal. This is important in applications where you need to prevent leaks or cross-contamination.

Installation and dismantling of ball valves

Installation and disassembly of ball valves can vary depending on the application and the specific type of ball valve, but there are some general steps that apply to most cases.

Installing a ball valve typically involves finding a suitable location between two pipelines and connecting the ball valve to the pipelines using fittings and gaskets. It is important to make sure that the ball valve is of the correct size and configuration and that it is designed to handle the expected pressure and temperature loads in the system.

During installation, make sure to tighten all fittings around the ball valve, but avoid over-tightening as this can damage the ball valve. It is also important to check that the ball valve is compatible with the material used in the pipe.

Dismantling a ball valve typically involves shutting off the valve or unscrewing the valve leading to the ball valve and relieving the pressure in the pipe. Then, locate and remove any fittings that hold the ball valve in place and remove any gaskets.

After removing the ball valve, inspect it for any signs of damage or wear, such as cracks, corrosion, or loose parts. If it is necessary to replace the ball valve, install the new ball valve using the same procedure as the installation.
