Trunnion Ball Valve Manufacturer in Germany
Valvesonly Europe is a Trunnion Ball Valve Manufacturer in Germany, supplying heavy-duty trunnion mounted ball valves for high-pressure, large-size, and critical pipeline applications across Europe. These valves are designed for reliable shut-off, low operating torque, and long service life in oil and gas, LNG, petrochemical, power, chemical, and industrial process systems.
A trunnion ball valve is selected where pipeline pressure, valve size, and sealing reliability are important. Unlike a floating ball valve, the ball is mechanically supported by trunnions at the top and bottom. This fixed-ball design reduces seat load, lowers operating torque, and allows smooth operation even in high-pressure service.
Function and Working
In a trunnion mounted ball valve, the ball remains fixed in position while spring-loaded seats move toward the ball to create sealing. Line pressure assists the seat sealing action, making the valve suitable for demanding shut-off applications. This design also allows double block and bleed, cavity pressure relief, and safe isolation in critical pipeline systems.
Advantages of Trunnion Ball Valves
- Suitable for high-pressure and large-bore pipelines
- Lower operating torque compared to floating ball valves
- Double block and bleed design available
- Fire-safe and anti-static construction
- Reliable sealing for gas, liquid, and hydrocarbon service
- Suitable for manual, pneumatic, electric, and hydraulic operation
- Long service life with reduced seat wear
