Single Weld Joint Ball Valve
  • Fully-welded ball valve is widely used in oil and natural gas gathering and pipeline transportation, Our single weld joint ball valve are developed by our technician, artistically designed and more practical. Our ball valve is in accordance with two-way sealing valve seat, automatic discharge pressure at the same time, fire prevention, anti-static function.
  • Small volume, Light weight, Split & Fixed type metal or soft sealing, Double seat, Double block and bleed, Single weld structure, Advanced manufacuture technology, Reasonable sealing, Stable performance, Long life.
