Hastelloy C-4 Valve Balls Hollow Trunnion Ball Without Stem

Valve trunnion ball usually refers to a key component in ball valves. A ball valve is a valve that uses a sphere as an opening and closing member. One hemisphere of the sphere is fixed on the valve stem, while the other hemisphere can rotate to control the flow of fluid. In ball valve design, the trunnion ball refers to the part of the ball that is usually mounted on the trunnion of the valve, allowing the ball to rotate when the valve opens and closes.

The main functions and uses of valve trunnion balls include:

• Flow Control: By rotating the trunnion ball, the flow of fluid through the valve can be controlled. When the ball is aligned with the valve channel, fluid can pass through smoothly; when the ball is rotated perpendicular to the channel, fluid is blocked from flowing.
• Opening and closing operation: The trunnion ball moves with the rotation of the valve stem to open and close the valve.
• High pressure resistance: The trunnion ball is designed to withstand high pressure differences to ensure the sealing performance of the valve in high pressure environments.
• Wear and Corrosion Resistance: Trunnion balls are usually made of wear and corrosion resistant materials such as stainless steel, nickel alloys or other special alloys to ensure that they maintain their functionality and performance over long periods of use and under various operating conditions.
• Reduce leakage: The design and material selection of the trunnion ball help reduce leakage when the valve is closed and improve the sealing performance of the valve.

The valve trunnion ball is an important component of the ball valve, which directly affects the use effect and life of the valve. In the chemical, oil, gas, pharmaceutical and other industrial fields, especially where high pressure resistance, wear resistance and corrosion resistance are required, valve trunnion balls play a key role.
