Introduction
Follow these instructions when installing, operating, or servicing
the product.
Application Limits
These products are intended for use in general purpose
compressed air systems only.
Installation
1. Install the Regulator as close as possible to the application.
2. Install the unit with the air flowing through the body in the
direction indicated by the arrow.
3. Gauge ports (1/4") are provided in either side of the
regulator body for installation of a gauge or use as an
additional outlet port. Plug unused port(s). System piping
should be same size as regulator porting. In systems with a
cyclic demand, the regulator should be located upstream of
cycling device.
Operation
Maximum pressure rating is 300 psig (21 bar). Temperature
range is 32°F to 150°F (0°C to 65.5°C).
1. Before turning on the supply air pressure, turn the
regulator adjusting knob counterclockwise until there is no
load on the regulating spring.
2. Turn on the supply air pressure and then turn the adjusting
knob clockwise until the desired secondary pressure is
reached.
3. To avoid minor readjustment after making a change in
pressure setting, always approach the desired pressure
from a lower pressure.
4. When reducing from a higher to a lower setting, first
reduce to some pressure less than that desired and then
increase to the desired pressure.
Maintenance
1. The regulator can be disassembled for servicing without
removal from line.
2. Occasionally remove bottom plug and clean plug, body and
valve seat.
3. TO DISASSEMBLE — shut off air to regulator and vent air
line on both sides of regulator. Turn adjusting knob
counterclockwise to relieve compression on spring.
Remove the knob cover cap, screws, cover and spring.
Diaphragm assembly can now be removed. By removing
bottom plug and spring the valve stem can be removed
from the bottom of the regulator.
4. IF UNIT WILL NOT REGULATE TO DESIRED PRESSURE
or if pressure becomes excessive - remove bottom plug,
spring, and valve assembly. Clean all parts and check valve
seat for wear or damage. Replace worn or damaged parts.
5. If excessive air leaks continuously from relief hole, the
regulator should be taken out of service and a
recommended repair kit installed, as listed under Repair
Kits and Replacement Parts.
6. WHEN REPLACING DIAPHRAGM ASSEMBLY — The
PRP-95-960 diaphragm assembly is a relieving-type
diaphragm.
! WARNING
To avoid unpredictable system behavior that can cause personal injury
and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.
• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.
! WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.
