Introduction
The
B75 Pressure Regulator
is a specialized control valve which
reduces the upstream supply pressure level to a specified constant
downstream pressure. Pneumatic equipment that is operated at a
higher than recommended pressure levels wastes the energy which
generates that pressure, creates a potential safety hazard, and wears
prematurely. The B75 is a balanced poppet, diaphragm style regulator
available in either relieving (standard) or non-relieving (K suffix after part
number) design. The
B75 Integral Filter/Regulator
incorporates the
R75 regulator with the filtering capabilities of the F75 Filter removing
impurities from the airstream two ways - dynamically by centrifugal
force, by which the deflector throws out heavier particles and entrained
water; and statically through the filter element itself, which filters out the
smaller particles. The B75 Filter/Regulator provides enough filtration for
most pneumatic applications, however, in situations where water and/or
oil aerosols must also be filtered out a F71 coalescing filter should be
installed also. Follow these instructions when installing, operating, or
servicing the product.

CAUTION
Polyurethane bowls, sight glass and sight domes on these units may
be attacked by certain chemicals. Never use solvents like carbon
tetrachloride, trichlorethylene, acetone, or paint thinner to clean any
parts. These elements can cause crazing or failure of the plastic parts.
The polyurethane resin parts are compatible with most hydrocarbon
based synthetic lubricants but, before using, check with the manufacturer
of the lubricant or oil for compatibility with polyurethane resin.
TO CLEAN POLYURETHANE BOWLS USE MILD SOAP AND WATER
ONLY!

WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.
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.
