Hard Face Sealing Ball Valve
The hard-sealed ball valve is a high-performance valve with a metal sealing structure and excellent high-temperature resistance, high-pressure resistance and wear resistance. It is widely used in the petroleum, chemical, electric power, metallurgy and other industries, suitable for high-temperature, high-pressure, highly corrosive media and working environments containing particles or impurities.
Product Features
- Excellent high-temperature and high-pressure resistance
Adopting a metal hard seal structure, it is suitable for extreme working conditions of high temperature (up to 600°C) and high pressure (up to PN420).
- Wear resistance and long service life
The ball and valve seat are made of high-hardness alloy materials (such as tungsten carbide, stainless steel, etc.), with excellent wear resistance and long service life.
- Zero leakage seal
The precision-machined ball and valve seat cooperate to ensure zero leakage when the valve is closed, meeting the strict sealing requirements.
- Adapt to complex media
Suitable for media containing particles, impurities or highly corrosive media, such as steam, gas, mud, etc.
- Multiple operation modes
Support manual, pneumatic, electric or hydraulic operation to meet the control needs of different scenarios.
- Multiple connection methods
Provide flange connection, butt welding connection and other methods to meet the installation requirements of different pipeline systems.
