Water pressure regulator J72

for gasdiaphragmspring

Overview The J72 Series 3/4 inch spring loaded regulator provides accurate, stable pressure control for demanding high- and low-pressure gas and liquid applications. It regulates inlet pressures up to 414 bar with selectable outlet control ranges to meet process requirements. A 10 mm valve seat and sensitive piston or diaphragm sensing ensure stable delivery as inlet pressure varies. 316L stainless steel construction, ANSI FCI 70-3 Class VI and API 598 tight shutoff, and temperature capability down to -50 °C with appropriate elastomers support severe-service operation. Standard connections include 3/4" NPT or BSPP ports, 1/4" gauge ports and a 1/8" ported vent. Certifications include ATEX, PED and EN 12266-1. Options: tamper-proof cap, panel mounting, NACE compliance, ASTM G93 Level C cleanliness.
