Installation
Clean all pipelines to remove dirt and scale before
installation.
Apply a minimum amount of pipe compound to the male
threads of the fitting only. Start with the third thread
back and work away from the end of the fitting to avoid
the possibility of contaminating the regulator. Install the
regulator in the air line.
The inlet and outlet connections are labeled on the un-
derside of the regulator with the arrows pointing in the
direction of the flow. Tighten connections securely.
Avoid undersized fittings that will limit the flow through
the regulator and cause a pressure drop downstream.
For more information, see Figure 1. “Outline Dimen-
sions”.
NOTE:
Oil free air must be applied to the
regulator. Use a filter to remove dirt and
entrained liquid in the air line ahead of the
regulator. If an air line lubricator is used, it
MUST be located downstream of the
regulator, to avoid interference with
regulator performance.

Maintenance
To clean the Model 10V, use the following
procedures:
1.
Before assembly, shut off the valve that is
supplying air to the regulator. This is to prevent
air from escaping.
It is not necessary to
remove the regulator from the air line.
2.
Remove the two Screws from the bottom of the
unit.
3.
Pull out the Inner Valve Assembly. Wash the
Seat on the Inner Valve Assembly carefully.
4.
Wipe off any particles that may be attached to
rubber Seat Ring in Body.
5.
Replace the assembly carefully.
6.
Keep the vent hole in the Bonnet clear for proper
regulator operation. Lubricate the adjusting
screw with Molycote “G”.
