SR1 Series Stainless Steel Small Flow Pressure Regulator

The SR1 employs a precision single-stage diaphragm pressure-reducing structure, ensuring extremely stable output pressure through pressure transmission via a high-performance stainless steel diaphragm. It can confidently handle various high-purity, corrosive, and toxic gases. The valve body is constructed from premium 316L stainless steel, the seat is made of PCTFE or PTFE, and the diaphragm is made of Hastelloy or 316L stainless steel. This advanced material combination allows it to perform exceptionally well in harsh temperatures ranging from -40°C to 74°C. Its technical parameters are highly competitive, with a CV value precisely controlled at 0.08. A 1.5 times maximum input pressure safety margin provides a solid guarantee for long-term operation in high-pressure environments, and its lightweight 0.9kg design allows for flexible panel or wall mounting.
