Pneumatic High Platform Ball Valve _ Electric High Platform Ball Valve

Comparative analysis of pneumatic high platform ball valves and electric high platform ball valves, comprehensive technical characteristics, application scenarios, and market data:

1、 Core structure and working principle
High platform design
The top of the valve body integrates a standardized actuator installation platform (ISO 5211 standard), which can directly install pneumatic/electric actuators without the need for transition brackets.
The sphere adopts a floating or fixed structure, with an O-shaped flow channel design, and the flow resistance approaches zero when fully opened.
Differences in driving methods
Pneumatic type: The piston actuator is driven by compressed air, with a response speed of ≤ 0.05 seconds/time, suitable for fast cutting scenarios.
Electric type: motor-driven, supporting 4-20mA signal adjustment, with an adjustment accuracy of ± 1%, suitable for continuous flow control.
2、 Performance comparison
Parameter Pneumatic high platform ball valve Electric high platform ball valve
Sealing grade ANSI Class VI (soft seal) Metal hard seal can reach ANSI Class V
Applicable pressure PN1.0~PN6.4MPa PN1.0~PN4.0MPa
