Low Set Pressure / Very Low Flow Pressure Regulating Valves

The JRHL Series is a line of low flow pressure regulators that have the ability to handle low set pressures and very low flows with less offset than valves with small diaphragm. The durable valve body and metal trim components are machined from 316L SST barstock. The valve is outfitted with the rugged Jorlon diaphragm and Teflon, PEEK or EPDM seats for ANSI Class VI shutoff. USDA and FDA approved soft goods available upon request.
