Note:
The length of the ball valve structure and the size of the connecting flange are designed and manufactured according to JB/T79 standards or user requirements.
The actuator models * * */* * are respectively pneumatic actuator double acting/single acting (spring reset).
The actuator models adapted to different valve torques and media may vary, and the relevant dimensions may change accordingly.
The above actuator configuration and data all use soft sealed (F) valves. Please consult our company for the configuration and data of hard sealed valves.
