JSBLFLP Series by Steriflow Valve

Compact, High Purity, Low Flow, Low Pressure, Back Pressure, Jorlon Diaphragm with lifetime warranty Size ranges: 3/8", 1/2", 3/4"; Cv's: 0.5, for relief valve sizing: 0.15; 0.15 , for relief valve sizing:0.25; 0.25, for relief valve sizing: 0.35; 0.35,l for relief valve sizing: 0.45 Spring range: 2-15 psi; 10-25 psi; 15-40 psi

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.
