Back Pressure Regulating Valves for Bio-Pharma
Gas Applications
J-Pure is the rst fully drainable high purity gas back pressure
regulator designed and built specically for hygienic, ASME BPE
gas applications.
Traditionally, regulator manufacturers adapted their industrial
gas regulators for use in biopharm by simply changing the construction materials and surface nish. Not so with the J-Pure
Series Model JSB.
• It's been designed specically to eliminate all threaded connections and contaminant traps below the diaphragm.
• It is completely drainable out the inlet and outlet (an industry rst in compact hygienic regulator design), and compatible with CIP and SIP practices.
• The simple trim design facilitates quick trim change out and
cleaning without valve removal or complete disassembly.
The durable valve body and metal trim components are machined from ASTM A479 316L SST barstock and nished to
ASME BPE SF5 (20Ra micro-inch (0,5 Ra μm), electropolished) standard. The valve is outtted with the rugged Jorlon
diaphragm and Teon or PEEK seats, all FDA approved, USP
Class VI compliant materials. These materials of construction
enable the JSB to withstand the rigors of continuous SIP and
CIP processes if required.
Features
• Fully drainable with no threaded connections, or contaminant traps below the diaphragm
• In-line removable seat and trim signicantly reduce maintenance time
• Barstock construction guarantees material integrity and
surface nish
• High ow rate coupled with high rangeability reduces need
for reduced trim sizes
• Minimized internal volume
• Proprietary Jorlon diaphragm material provides exception-
ally long life and CIP/SIP capability, and FDA and USP
Class VI compliance
• Soft seat material for ANSI Class VI shutoff

Typically used in Biopharm or parenteral installations for modulating pressure relief during lling, or other back
pressure applications. Ideal for clean
gases typically found in
bio-pharmaceutical, pharmaceutical
and food & beverage processes including:

Captured Vent
The captured vent design is for maximum safety for the user when handling toxic or hazardous media. It
features a 1/8" FNPT port located on the spring housing. The user can easily tube this vent to a safe location.
Panel Mount
The panel mount feature requires a panel cut out of 1-1/2" allowing insertion of the threaded spring housing, and a panel mount ring to secure the regulator against the panel.

To select a valve with the proper Cv:
1. Convert pressure and ow units to those shown on graph.
2. Select the graph below with a ow range (x axis) that encompasses the minimum and maximum ows
of your installation, and with an appropriate outlet regulated pressure range (y axis). Note: Your max
ow cannot exceed either of the graphs, nor can your desired set point be below 4 psi, or above 125
psi. Note also that the maximum inlet pressure allowed is 150 psig.
3. Plot your desired set point on the graph you chose above, at the ow rate you expect that set point.
4. Pick an outlet pressure spring range ow curve that contains your set point. Eg. 50 - 125 psi, 35-60 psi, etc.
5. Draw a curve with the same slope as #4 above parallel to the spring range ow curve you have
chosen through your plotted set point. That curve approximates the ow of your valve under operating
conditions.
6. Note that you may also use the SFCV sizing program for Globe style valves to calculate approximate
ow or Cv.
