Warning: Steriflow Sanitary Pressure Regulators must only be used, installed, and repaired in accordance with these
Installation & Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event of
leakage or other malfunction, call a qualified service person; continued operation may cause system failure or a general
hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized fluid. Before disassembling a valve, be
sure to release all spring tension.
Please read these instructions carefully!
Your Steriflow/Jordan Valve product will provide you with
long, trouble-free service if it is correctly installed and main-
tained. Spending a few minutes now reading these instruc-
tions can save hours of trouble and downtime later. When
making repairs, use only genuine Jordan Valve parts, avail-
able for immediate shipment from the factory.
Ideal Installation Schematic
Preferred Installation
The valve is designed for sanitary service and it is as-
1.
sumed that it will be installed into a clean system. Un-
der these conditions, special considerations to protect
the valve such as providing line strainers at the valve
inlet are not necessary.
2. The regulator is to be installed with the inlet horizontal
and the outlet pointed down. This will provide the best
drainage inside the valve. These restrictions apply only
for drainage considerations; the valve will function in
any position. Contact factory for other possible orienta-
tions.
3. Steam regulators are best located at the highest point
in the piping with the take-off out of the top of the steam
header. This will minimize the possibility of water in the
regulator.

4. For best control, 3'-0" straight sections of pipe should
be installed on either side of the regulator.
5. Use caution in tightening commercial sanitary fittings.
Over-tightening can cause the gasket to extrude into
the flow passage.
6. If possible, install a relief valve downstream from the
regulator. Set at about 30% above the control point of
the regulator.
7. In gas or vapor service, select outlet piping that is at
least one pipe size larger than the inlet.
8. Operate the regulator within its pressure and tempera-
ture rating as stamped on the valve nameplate.
1. Slowly open the inlet shutoff valve and slowly turn the
adjusting screw until the desired inlet pressure is shown
on the inlet pressure gauge, without discharging fluid.
2. To change the controlled pressure, turn the adjusting
screw clockwise to increase the pressure, or counter-
clockwise to decrease the pressure.
3. Once the desired setpoint is obtained, run the thumb-
lock down until it reaches the top of the spring housing.
Then run the hex jam nut down to the top of the thumb-
lock and lock the two together. This will effectively keep
the adjusting screw from turning due to vibration, etc.
This is useful during the cleaning cycle (see section on
Clean-In-Place/Steam-In-Place.)
Warning: Never substitute an longer length adjusting
screw. The valve may fail to open and personal injury or
property damage could occur .
Caution: Make certain that there is no pressure in the
valve before loosening any fittings or joints. The fol-
lowing steps are recommended:
1. Close the inlet shutoff valve.
2. Turn the adjusting screw counterclockwise until there is
no pressure on the spring, allowing any trapped pres-
sure to release downstream.
