GOA uses natural gas or nitrogen gas as the motive power and hydraulic oil ad the driving medium to actuate the pipeline valve to a fully open to fully closed position. The common control functions include: local pneumatic operation, local hydraulic operation, automatic line break protection, remote control, and emergency shutdown (ESD), etc.

The LBP-1000 is an electric line break detection and protection system independently developed and manufactured by Zhonghuan for real-time monitoring pipeline pressure, pressure drop rate, etc. The LBP-1000 can provide a reliable guarantee for pipeline safety and integrity.
In an emergency situation such as a pipeline break, the LBP-1000 will automatically make a judgement and trigger a command to execute emergency shutdown of the upstream and downstream valves nearest to the broken point. After receiving the command, the actuator will immediately drive the pipeline valve to a safe position, while recording pipeline pressure date before and after the triggering point. It is possible to download and analyze the record.
Zhonghuan's LBP-1000 V6.1 has a static power requirement of 0.18W, applicable for solar or external power supplies. Zhonghuan's LBP-1000 V7.1 only has a static power requirement of several mW.
