JSR Series – Gas Pressure Regulator
The JSR Series is the first high purity gas pressure regulator designed and built specifically for hygienic, ASME BPE gas applications. The JSR Series has been designed specifically to eliminate the exposed threaded connections and permanent contaminant traps below the diaphragm. And, it features an in-line removable trim set to facilitate quick trim change out and cleaning without valve removal or disassembly. The durable valve body and metal trim components are machined from ASTM A479 316L SST barstock and finished to ASME BPE SF5 (20 Ra micro-inch, electropolished) standard. The valve is outfitted with rugged Jorlon diaphragm and Teflon, PEEK or EPDM seats and seats that are all FDA approved, USP Class VI compliant materials.These materials of construction enable the JSR Series to withstand the rigors of SIP and CIP processes if required. And, the new EPDM seat reduces lockup to less than 2.5 psig.
Applications: ideal for clean gases typically found in bio-pharmaceutial, pharmaceutical and food & beverage processes including: clean filter air, nitrogen, carbon dioxide, argon, oxygen, custom purge or blanket gas.
