High-pressure ball valve is a ball valve suitable for high-pressure working conditions. It is widely used in oil, natural gas, chemical industry, hydraulic system, water conservancy, power and other industries.

Features of high-pressure ball valve:

1. High-pressure resistance: usually can withstand 3,000 PSI (20MPa) ~ 10,000 PSI (70MPa) or even higher pressure.

2. Strong material: often made of stainless steel (SS316, SS304), carbon steel, alloy steel to ensure pressure resistance and corrosion resistance.

3. Strong sealing: PTFE (polytetrafluoroethylene), PEEK or metal seals are used to ensure zero leakage.

4. Compact structure: generally use floating ball or fixed ball structure to ensure stability under high-pressure environment.

5. Various connection methods:

-1. Threaded connection (NPT, BSPP, BSPT)

-2. Flange connection

-3. Compression fitting

-4. Butt welding/socket welding

Application areas of high-pressure ball valves

✅ Hydraulic system (hydraulic oil, high-pressure gas)

✅ Oil and natural gas pipelines

✅ High-pressure water jet system

✅ Chemical equipment (high-pressure chemical fluid control)

✅ Testing equipment (high-pressure air tightness test）
