SR4 Series stainless steel high pressure pressure regulator

The SR4 employs a more robust piston-type pressure reduction structure, specifically designed to handle ultra-high input pressure requirements of up to 6000 psi (approximately 41.4 MPa). Because diaphragms are prone to fatigue wear under high pressure, the piston-type structure provides stronger mechanical support and an extremely long service life, making it particularly suitable for extreme environments such as laboratory high-pressure testing, process control, and airflow scouring. Although its CV value is set relatively low at 0.06, its output pressure adjustment range is extremely wide, and both the main body and internal components are made of 316L stainless steel, ensuring chemical inertness to high-purity and corrosive gases. From a system integration perspective, the SR4 is the core of the high-pressure gas cylinder container terminal pressure reduction system, enabling the safe and stable introduction of high-pressure gas into subsequent processing units.
