JSBLF Series

The JSBLF is a fully drainable compact back pressure regulator designed and built specifically for hygienic, ASME BPE low flow gas and liquid applications. It is also able to withstand the rigors of continuous SIP and CIP processes if required. Typically Used in Biopharm or parenteral installations for modulating pressure relief during vessel filling, or for continuous sparge or blanket gas venting. Ideal for use in compact, low flow liquid back pressure applications in buffer dilution, pump head pressure control, and for DP maintenance across filter membranes or chromatography columns.
