Instruction of Pneumatic Ball Valve Series

Pneumatic actuator: Use new-style AT pneumatic actuator, it has Double acting and Single acting (Spring return). Design according to rack-and-pinion structure.. Big diameter valve install AW type pneumatic actuator, AW pneumatic actuator design according to pull-plug type structure, it have more large torque, and has Double acting and Single acting (Spring return). Refer to our stylebook of pneumatic actuator for more details information.

Feat seat structure: Floating ball valve use lip elastic seal, it has better sealability and longer working life. For the low pressure and ultra low pressure or vacuum condition, it adopts leaf spring loading to keep longer sealability. Material of middle temperature and high temperature ball valve adopt pare-position toluene and metal.

Firesafe Structure: Ball valve according to the working conditions environment to design as Firesafe structure. Ball valve fireproof design mgf.API6D and JB/T6889
