Low Set Pressure / Very Low Flow Pressure Regulating Valve

The JRLL Series are low flow regulators designed and built specifically for very low pressure applications. The durable valve body and metal trim components are machined from 316L SST barstock. The valve is outfitted with a sensitive PTFE Jorlon diaphragm for accurate low pressure sensing and Teflon, PEEK, KEL-F and EPDM seats for ANSI Class VI shutoff. USDA and FDA approved soft goods available upon request.
