JSR Series – Bio-Pharma Gas Regulator

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 (20Ra micro-inch, electropolished) standard. The valve is outfitted with the rugged Jorlon FDA approved, USP Class VI compliant materials. These materials of construction enable JSR to withstand the rigors of SIP and CIP processes if required.
