SR2 Series stainless steel medium flow pressure regulator

The SR2 achieves a CV value of 1.1 through optimized internal flow channels, specifically designed for gas systems requiring medium flow rates. It also employs a single-stage diaphragm structure, equipped with an electroplated 316L stainless steel body and top cover, ensuring no secondary contamination occurs when delivering standard or specialty gases. Its robust 1.6kg structure provides superior mechanical shock resistance at higher flow rates, and the inlet and outlet port specifications can be selected in various forms, including 1/2" NPT(F), greatly enhancing system adaptability. Its core diaphragm sensor is highly sensitive, providing real-time feedback and rapid compensation for pressure fluctuations, making it widely applicable in industrial settings such as semiconductors, power plants, and coal mines where moderate flow stability is required.
