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.
