Compact, High Purity, Low Flow, Low Pressure, Back Pressure, Jorlon Diaphragm with lifetime warranty

The JSBLFLP is a fully drainable compact back pressure regulator
designed and built specifically for hygienic, ASME BPE low flow
and low pressure gas and liquid applications.

  • It's been designed specifically to eliminate all threaded connections
    and contaminant traps below the diaphragm.
  • It is completely drainable (an industry first in compact hygienic
    regulator design), and compatible with CIP and SIP
    practices. See drainability guideline on page 6.
  • The simple trim design facilitates quick trim change out and
    cleaning without valve removal or complete disassembly.
