Installation
1. The regulator should be installed with reasonable
accessibility for service whenever possible - repair service
kits are available. Keep pipe and tubing lengths to a
minimum with inside clean and free of dirt and chips. Pipe
joint compound should be used sparingly and applied only
to the male pipe - never into the female port. Do not use
PTFE tape to seal pipe joints - pieces have a tendency to
break off and lodge inside unit, possibly causing
malfunction.
2. Install regulator so that media flow is in the direction of
arrow. Installation must be upstream (high pressure) side
and as close to the devices it is to service (valve, cylinder,
tool, etc.). Mounting may be in any position.
3. Gauge ports are located on both sides of the regulator
body for your convenience. It is necessary to install a
gauge or pipe plugs into each port during installation.
4. For protection against rust, pipe scale, and other foreign
matter, install a filter on the upstream (high pressure) side
as close to the regulator as possible.
Operation
1. Before turning on the media source turn the T-handle
counterclockwise until compression is released from the
Control Spring. Then turn on media source and adjust
regulator to desired secondary pressure by turning T-handle
clockwise.This permits pressure to build up slowly, preventing
any unexpected operation of the valve, cylinders, tools, etc.,
attached to the line. Adjustment to desired secondary
pressure can be made only with primary pressure applied
to the regulator.
2. To decrease regulator pressure setting, always reset from a
pressure lower than the final setting desired. For example,
lowering the secondary pressure from 550 to 410 kPa (80
to 60 PSIG) is best accomplished by dropping the secondary
pressure to 350 kPa (50 PSIG), then adjusting upward to
410 kPa (60 PSIG). Tighten the Locking Nut on the T-handle
to lock the pressure setting.
Reduced Pressure Spring Ranges
“A” Range = 1 – 25 PSI (1/4", 3/8", 1/2" Only)
“B” Range = 2 – 60 PSI (1/4", 3/8", 1/2" Only)
“C” Range = 2 – 125 PSI (ALL)
“D” Range = 5 – 250 PSI (ALL)

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 media source and depressurize all media 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, media 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.
