Ball valves are designed so that they can be opened or closed with a simple 90° turn. Their key feature is a ball with a through-bore, which provides a clear advantage over gate and globe valves.

Key Characteristics of Ball Valves

Ball valves offer consistent, tight shut-off with very low pressure loss, thanks to a precisely machined ball. They are available with full or reduced bore and can be operated using different actuation methods. Their short switching time, minimal maintenance requirements, and options such as stem extensions make them suitable for a wide range of applications in industry, utilities, and plant engineering.

Accurate Flow Control

The seats found in ball valves—made from Teflon, neoprene, or fluorinated polymers—offer outstanding sealing performance and ensure consistent tightness at low and medium temperature ranges.

Temperature Range of Ball Valves

Whether for extremely cold or very hot operating conditions, selecting the appropriate sealing materials—such as graphite or high-performance plastics—allows ball valves to be used in temperatures from as low as −200 °C to well above 500 °C.

Compact Design and Easy Handling

Compared to many other valve types, ball valves are more compact. They can be fully opened or closed with a quarter turn and require only low operating torque, making them ideal for both automated systems and manual operation.

Key Features of Ball Valves

Our high-performance ball valves provide secure shut-off with minimal flow loss and can be used with water, gas, oil, steam, and other media. Optional actuators and stem extensions offer high flexibility, making them well suited to industrial applications with demanding requirements for tightness, temperature resistance, and pressure stability.

Advantages of ball valves

✓ Quick quarter-turn operation
✓ Tight shut-off with low torque demand
✓ More compact than most other valve designs

Disadvantages of Ball Valves

✓ Standard ball valves are not suitable for precise throttling

✓In slurry or similar applications, suspended solids can accumulate in body cavities, causing wear, leaks, or valve malfunction

Trunnion-Mounted Ball Valve

A trunnion-mounted ball valve incorporates additional mechanical support at both the top and bottom of the ball. This construction is used particularly for larger sizes and higher pressure classes. Since the ball is supported at two points, operating torque is significantly reduced. The pipeline pressure is taken up by the stem anchored in the trunnion, preventing excessive friction between the ball and the seats. As a result, the valve remains easy to operate even under full pressure.

Floating Ball Valve

In a floating ball valve, the ball is supported only by the stem and is free to move slightly downstream. When pressure is applied, the ball is pushed against the seat, creating a tight, positive seal.

Full Bore

A Full Bore (or Full Port) ball valve has an internal bore that is nearly the same diameter as the adjacent pipeline. This design minimizes friction and pressure drop. Because there is no restriction to flow, full-bore valves tend to be more expensive but are preferred in applications where pigging is required. They are commonly used in the chemical, petrochemical, and refinery sectors.

Reduced Bore

Reduced Bore (or reduced port) ball valves have an internal flow path one or two nominal sizes smaller than the pipeline. This creates a restriction that generally results in greater energy losses.
