Pneumatic extended stem stainless steel CF8 flange ball valve is a valve switch device that uses pneumatic single acting or double acting pneumatic actuators to regulate pipeline flow and cut off pipeline media. Equipped with an extended valve stem, the distance between the valve body and the actuator can be extended to better isolate some reactions caused by the medium and the actuator and accessories, such as high-temperature media, low-temperature media, insulation layer that needs to be thickened or locally limited, all of which can be solved by the extended valve stem; The valve body material of the ball valve includes stainless steel 304 (CF8), stainless steel 316 (CF8M), super duplex steel 2205/2507/904/310S, etc. Pneumatic actuator accessories can also choose limit switches (feedback devices), solenoid valves (electrically controlled pneumatic through reversing), positioners (analog adjustment), etc
