Two-stage pneumatic ball valve

The two-stage pneumatic ball valve is mainly used for automatic control in loading and unloading systems, and is suitable for application scenarios where there are clear requirements for the opening and closing process and safety status. Through the two-stage action logic, the valve realizes staged opening and closing control, which helps to improve the safety and controllability of the loading and unloading operation process.

The valve actuator can use a three-position pneumatic actuator or be controlled by a split control electrical accessory. During operation, the valve can complete the initial opening and full opening in the set sequence, or close in the opposite sequence, which is used to reduce the instantaneous impact of the medium and reduce the load on pipelines and related equipment, suitable for liquid or gas loading and unloading scenarios.

The valve's fault state is generally set as closed. In case of abnormal air supply or control signal, the valve can automatically close to prevent medium leakage and meet the safety requirements during loading and unloading operations. The valve supports local operation and remote control, and can be configured with travel switches, interlock signals, and communication modules, making it easy to connect to DCS or PLC systems for status monitoring and centralized management.

The action time of the valve can be selected and adjusted according to the actual working conditions, which can both meet the requirements of loading and unloading efficiency and also take into account the stability of system operation. When used as a self-control valve for loading and unloading, the two-stage pneumatic ball valve can ensure operational safety while improving the reliability and flexibility of on-site control.
