"O" type to cut off the ball valve can be realized media pass-through, to achieve the purpose of access regulation, applicable to both cut off the occasion. Its connected to the actuator, has compact structure, small size, light weight, small resistance, the advantages of stable and reliable. According to user requirements configuration GT, ats quarter-turn pneumatic piston type actuators. Pneumatic piston type actuators for the piston driven gear and rack, pinion and rack drive actuator, has small volume, large output torque, work balance and long life. And can install solenoid valves, limit switches, valves locator implementation such as two and proportional control.

Product features

Flange floating ball valves also used to pour sealing valve stem design, fire prevention, anti-static function, automatic pressure release and locking devices such as structure design, it is mainly used for cutting, distribution, and change the flow direction of medium, suitable for chemical, oil, natural gas, metallurgical and other industries and medium containing hydrogen sulfide, serious corrosion of long distance natural gas pipeline, etc.

Flange of floating ball valve ball by two seat clamping, supporting shaft support, contain a "floating" state. Due to the use of special design of double inclined plane elastic sealing ring, effectively reduce the sphere and the friction between the sealing ring, reduce operating torque. When the medium pressure is small, sealing ring and ball contact area is lesser, reason has larger sealing pressure, ensure reliable sealing. When the medium pressure, sealing surface contact with the sphere area also increases accordingly, so the sealing ring can bear larger medium thrust without damage, to ensure reliable sealing.
