Product usage:
It is applied to various pipeline equipment such as urban gas, urban heating, petrochemical industry, shipbuilding, steel, pressure regulating station, power plant, etc
Product features:
The all welded ball valve adopts seamless steel pipe assembly and welding. The whole valve is designed without bolts, and there will be no external leakage caused by handling collision and casting sand hole. It is light and convenient for transportation and installation. Since the valve seat is a movable design loaded by a spring or a butterfly spring, it has strong adaptability to changes in pressure and temperature, and there will be no leakage within the marked pressure and temperature range.
