Bronze Turnnion Ball Valve

Waits Valve offers the advanced Bronze Turnnion Ball Valve, a high performance ball valve with a fixed ball structure and bidirectional sealing design. Unlike floating ball valves, the ball of this valve is fixed by upper and lower "bearing supports" and does not move with pressure, making it suitable for opening and closing control under high pressure, large diameter or severe working conditions. Waits Valve has established a global leading position with innovative product engineering, strict quality assurance procedures and predictive service systems.

Product Description

The valve body of Waits Valve Bronze Turnnion Ball Valve is made of high quality corrosion resistant bronze, which is particularly suitable for working conditions such as seawater, salt water, and low corrosive chemical media. In the bronze fixed ball valve, the fixed ball realizes axial sealing along the axis of the flow channel, so that the sealing seat is not prone to excessive friction. It is widely used in marine engineering, shipbuilding, water treatment, cooling systems and industrial process control.

Product performance feature:
Excellent performance in corrosive environments (seawater, chemical media) with long term oxidation resistance and biofouling prevention, suitable for marine engineering and chemical pipelines.Trunnion mounted design secures the ball with axial bearings, preventing pressure induced displacement and ensuring uniform sealing surface wear, ideal for high pressure and large diameter applications.Combines soft/hard sealing structures to achieve leakage rates <0.01% while maintaining long term sealing integrity.High wear resistance and thermal stability minimize maintenance frequency caused by abrasive media or thermal stress.
Application areas
Ship and offshore platform piping systems
Cooling systems and heat exchangers
Water treatment and filtration devices
Industrial process pipeline automation
Port and seawater desalination systems
Control of low-corrosive fluids in petroleum and chemical transportation
