Fully Welded Ball Valve
SEV Fully welded ball valve is made by engineers with 30 years experience on valve design and manufacture. It is successfully developed according to the latest technical standard. It is mainly applied for both long distance pipeline delivery of petroleum, natural gas and coal gas and for urban gas conduit system. Because of the particular characteristics of fully welded ball valve, the capability to endure pipeline stress. non-corrosibility, safety, weather resisting property and long run reliability is fully considered when designed. There are many operating patterns as gearbox driven. air-driven, electric-driven, air-hydraulic driven and various special controlling forms.
