                  Structure: floating ball core

                  [valve assembly]
                  Seat seal: 304, 316, 316L+STL\ tungsten carbide
                  Spool material: 304, 316, 316L+STL\ tungsten carbide
                  Stem material: 304
                  Applicable medium: water, oil, steam and so on

                  [performance]
                  Through design, the flow resistance is small and the pressure is low
                  Anti blow stem design, safe and reliable
                  Stem explosion proof design
                  Sealing surface, the ball core surface can be spray welding treatment or tungsten carbide
                  Allowable pressure difference: less than nominal pressure 1.6MPa
                  Leakage: zero leakage
                  Return difference: + 2.5%

                  [pneumatic actuators]
                  Double acting: ventilation, ventilation, gas failure to maintain the current position
                  Single action: ventilation, breathe air to open, closed source fault
                  Single acting air to close off gas and ventilation: open source, open fault
                  Optional accessories: reversing solenoid valve, limit switch, air filter pressure reducing valve, electrical positioner, hand wheel mechanism, retaining valve, electrical part can be selected explosion-proof
