Fully Welded Ball Valve
Floating ball valve fully welded
Usage
Applicable to various pipeline equipment such as city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants, etc.
Features
The fully welded ball valve is formed by welding seamless steel pipes. The entire valve is a bolt-free design, which will not cause external leakage due to handling collisions and casting sand holes. It is also light in weight and easy to transport and install. Since the valve seat is a movable design loaded by a spring or butterfly spring, it has a strong adaptability to changes in pressure and temperature, and will not cause any leakage within the specified pressure and temperature range.
