Ball Valves

Ball valves are industrial valves with a spherical throttling device for shutting off, regulating or controlling flow rates in piping systems. They are available in various designs, including 2-piece flanged ball valves and trunnion-mounted versions. The valves are used in industrial fluid and process engineering.

Ball valves are not butterfly valves, gate valves or check valves, but valves with a rotating spherical element as the shut-off component.

Ball Valves: Frequently Asked Questions

How do ball valves work?

Ball valves use a spherical throttling device with a bore that opens or closes the flow by rotating 90 degrees. In the open position, ball valves allow nearly unrestricted flow. Sealing is achieved through sealing rings pressed against the ball surface.

What types of ball valves are available?

Ball valves are offered in various designs, including 2-piece flanged ball valves and trunnion-mounted versions. The design depends on operating pressure, nominal size, and application conditions. Trunnion-mounted ball valves are particularly suitable for large nominal sizes and high pressures.

In which industries are ball valves used?

Ball valves are used in the gas, chemical, petrochemical, and food industries. They are suitable for industrial fluid and process engineering where reliable shutoff and flow control are required. These valves perform well with both liquid and gaseous media.

What are the advantages of ball valves over other valve types?

Ball valves offer quick actuation through 90-degree rotation, low pressure drops when open, and excellent sealing performance. They are low-maintenance, versatile, and suitable for a wide range of media. Additionally, ball valves enable simple visual verification of the switching position.

What is the function of Double Block & Bleed ball valves?

Double Block & Bleed ball valves are specialized solutions with dual shutoff function and a vent opening between the shutoffs. This design enables safe isolation of system components and controlled draining of residual media. They are particularly used in safety-critical applications in the gas and petrochemical industries.
