Häger GmbH & Co. KG ANSI-Ball Valves
Ball valves have a special feature that allows opening and closing with a 90° rotation. The ball valve is equipped with a drilled ball, offering a significant advantage compared to gate valves and globe valves.
The key features of ball valves
Ball valves provide reliable, tight shut-off with minimal flow loss thanks to a precisely matched ball. They are available with full or reduced bore and various actuation types. Their fast switching time, low maintenance, and options like stem extensions make them suitable for diverse applications in industry, utilities, and plant construction.
Precise flow control
The seats used in ball valves, made of Teflon, neoprene, or fluorinated polymers, provide excellent sealing properties and ensure reliable tightness at low to medium temperatures.
Temperature Range of Ball Valves
Whether for extremely cold or hot processes – by selecting suitable sealing materials such as graphite or high-performance plastics, ball valves are suitable for temperatures ranging from -200 °C up to over 500 °C.
Compact Design and Easy Operation
Ball valves are smaller than many other valve types, allow quick opening and closing with a 90° turn, and require only low torque—making them ideal for both automated and manual applications.

The key features of ball valves
Our high-performance ball valves ensure reliable shut-off with minimal flow loss, are suitable for water, gas, oil, steam, and other media, and offer maximum flexibility thanks to optional actuators and stem extensions – ideal for industrial applications with demanding requirements for tightness, temperature, and pressure resistance.
Advantages of ball valves
✓ Quick quarter-turn open/close operation
✓ Tight sealing with low torque requirement
✓ More compact than most other valve types
Disadvantages of ball valves
✓ Conventional ball valves have poor throttling capabilities
✓ In slurry or similar applications, suspended particles may settle and become trapped in body cavities, leading to wear, leakage, or valve failure
Trunnion Mounted Ball Valve
A trunnion-mounted ball valve features additional mechanical anchoring at the top and bottom of the ball, making it suitable for larger and high-pressure ball valves. This specific mounting design reduces the operating torque, as the ball is supported at two points. Every ball in this configuration is pivot-mounted. The stem mounted on the trunnion absorbs the pipeline pressure, preventing excessive friction between the ball and the seats. As a result, the operating torque remains low even under full working pressure.
Floating Ball Valve
A floating ball valve is not held in place by a trunnion but is instead mounted only on the stem. As a result, the ball can sometimes shift slightly downstream. When this happens, the ball presses against the seat, creating a positive seal.
Full Bore
A Full Bore Ball Valve, also known as a Full Port valve, features a bore diameter that closely matches the diameter of the connected pipeline. This design minimizes friction and pressure loss across the valve. Since there is no restriction to fluid flow, Full Bore valves are typically more expensive. However, they are ideal for applications where pigging is required. This technology is commonly used in the chemical, petrochemical, and refinery industries.
Reduced Bore
Reduced Bore Ball Valves, also known as reduced port valves, are designed with a flow path that is one or two nominal sizes smaller than the pipeline. This results in a more restricted flow, which generally leads to higher energy losses.
