The regulator uses an air pilot design with a diaphragm-indirect operation type, providing reliable control from the start. In addition, it responds quickly even when secondary pressure fluctuates, allowing smooth and accurate performance. As a result, it maintains stable pressure regulation while supporting a large exhaust flow rate in a compact body, which increases overall efficiency. Beyond that, the compact structure boosts usability and enhances system performance. Finally, it also integrates seamlessly with all Multi Series components, enabling flexible and scalable system configurations.
