Pneumatic floating ball valve

[valve body]
Nominal diameter: DN20-DN250
Body material: WCB, 304, 316, 316L
Connection: flange
Pressure rating: PN1.64.0MPa
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
