Working Principle
The SEU valve functions as a 2/2 way normally closed (NC) valve. When air pressure is applied to the inlet port, the valve opens, allowing air to flow through. Upon removal of the pressure, the valve closes, trapping the air and preventing backflow. This mechanism ensures efficient and rapid exhaust of air from the system, improving overall performance and protecting the pipeline.
