Ball Valves
Stainless steel ball valves are particularly valued for their resistance to corrosion and extreme temperatures, which makes them suitable for aggressive media, high-pressure environments, and applications demanding long-lasting performance. Unlike other valve-types, ball valves offer a tight, leak-proof seal, making them effective in critical systems where leakage prevention is essential.

What are ball valves used for?
Ball valves are versatile components used to control the flow of liquids or gases. Their simple design, durability, and ability to provide a tight seal make them ideal for applications in industries such as water treatment, oil and gas, chemical processing, and HVAC systems.
How do high-pressure ball valves work?
High-pressure ball valves are designed to handle higher pressures by using robust materials and various types of gaskets and O-rings. The valve ball rotates inside the valve-housing, ensuring precise control of flow while withstanding high-pressure environments up to 500 bar.
What is the difference between a two-way and a three-way ball valve?
A two-way ball valve has one inlet and one outlet, controlling flow in a straight line. A three-way ball valve, on the other hand, features an additional port, allowing fluid to be directed or mixed between multiple pathways, making it suitable for more complex industrial systems.
