Product Entity Class
Ball Valves
Ball valves are shut-off valves with a perforated ball as the closure element that opens or closes the flow of liquids or gases through a 90-degree rotation. They are used in industrial piping systems for controlling and shutting off media. Sealing occurs via valve seats that enclose the ball.
Ball valves are not gate valves, check valves, or diaphragm valves, but exclusively rotatable ball shut-off valves.

Ball Valves: Frequently Asked Questions
How do ball valves work?
Ball valves feature a perforated ball as the closure element, operated by a 90-degree rotation. In the open position, the medium flows through the ball's bore, while in the closed position, the ball completely blocks the flow. Sealing is achieved through valve seats that enclose the ball, ensuring reliable shut-off.
Which industries are ball valves suitable for?
Ball valves are used in diverse industrial applications, particularly in the gas, chemical, petrochemical, and food industries. They are suitable for controlling and shutting off various media in piping systems. Due to their robust construction and reliable sealing function, ball valves are especially suited for demanding process environments.
What are the advantages of ball valves compared to other valve types?
Ball valves offer several advantages: The 90-degree rotation enables quick and easy operation. The through bore ensures minimal pressure loss in the open state. Ball valves also provide particularly reliable sealing through the valve seats and are robust against different media and operating conditions.
Which media can be controlled with ball valves?
Ball valves are suitable for controlling and shutting off both liquids and gases in industrial piping systems. Depending on design and material selection, they can handle aggressive chemicals, hydrocarbons, food products, or technical gases. The selection of the appropriate ball valve depends on the specific properties of the medium, pressure, and temperature.
What does 'Double Block & Bleed' mean for ball valves?
Double Block & Bleed is a specialized solution in ball valves that combines two shut-off points (Block) and a drain capability (Bleed) in a single valve. This design allows for safe isolation of a medium while simultaneously draining or venting the space between the two shut-off points. Ball valves with Double Block & Bleed function are particularly used in safety-critical applications in the gas and petrochemical industries.
