About the performance and application of hard seal trunnion ball valve

The hard seal fixed ball valve is a valve commonly used in industrial pipeline systems. It is named because its sealing pair is metal to metal (i.e. hard seal) and the ball is a fixed structure. Here are its main uses):

The main uses of the hard seal fixed ball valve:

1. High temperature and high pressure conditions: Suitable for high temperature fluids such as steam, hot oil, and boiler systems.

Can withstand high pressure environments and are widely used in power plants and petrochemical industries.

2. Strongly corrosive media: The metal sealing surface can be made of cemented carbide, alloy steel, Stellite alloy, etc., with strong corrosion resistance. Used in chemical industry, metallurgy and other occasions that require corrosive media.

3. Containing solid particles or abrasive media: The hard seal structure can prevent the problem that the soft seal is easily damaged by particles, and is suitable for media such as slurry and ash.

4. Pipeline transportation system: Widely used in oil and natural gas pipelines, especially long-distance pipelines, to adapt to complex outdoor environments. The ball is fixed and will not move after being pressurized, which is suitable for large-caliber and high-pressure scenes.
5. Emergency shut-off system: quick opening and closing, suitable for emergency occasions requiring quick shut-off.

Advantages and features of this valve:

1) Excellent sealing performance, can ensure sealing even under high temperature and high pressure.

2) Long service life and strong wear resistance.

3) Suitable for a variety of media: water, steam, oil, acid and alkali, natural gas, liquefied gas, etc.

4) Stable structure, not easy to leak due to pressure fluctuations.
