Back Pressure Reducing Valve JSBLFLP


Product description

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.


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.
