64 Series Pressure Reducing Regulators
W1943
Figure 1. 64 Series Regulator
Introduction
Scope of Manual
This manual provides instructions for the installation,
adjustment, maintenance, and parts ordering for
64 Series regulators. These regulators usually are
shipped separately for line or panel mounting or
installed on other equipment. Instructions and parts
lists for other equipment are found in separatemanuals.
Product Description
The 64 Series regulators are spring-loaded, direct-
operated devices typically used to deliver constant
reduced pressure of gaseous fluids to pilot-operated
controllers and other pneumatic instrumentation.
Type 64: Basic regulator for 3 to 15 psig
(0,21 to 1,03 bar) outlet pressures
Type 64R: Internal relief version of the Type 64
Type 64B: NH3 - service version of the Type 64

1. The pressure/temperature limits in this instruction manual or any applicable standard limitation should not be exceeded.
The Type 64R has an integral low-capacity relief
valve. The valve stem seats against a drilled hole
in the diaphragm plate. If the reduced pressure
should exceed the set pressure, the diaphragm lifts
off the valve stem so that a limited amount of excess
pressure can flow into the spring case and bleed out
through a screened vent.
A 64 Series regulator is also available with a
handwheel. An optional handwheel is available for
panel mounting.
Installation
! WaRnIng
Overpressuring a regulator or associated
equipment may cause leakage, part
damage, or personal injury due to
bursting of pressure containing parts or
explosion of accumulated gas. To avoid
overpressure, provide an appropriate
overpressure protection device (i.e., a
relief valve) to ensure that the ratings
listed in Specifications section will not
be exceeded. a regulator should be
inspected immediately for damage after
any overpressure condition.

1. All springs can be backedoffto 0 psig (0 bar). For the highestcapacityand most accurate control, use the lowest-range springthatcan be adjustedto the required setpoint.
2. �annotbeusedinanhydrousammonia(NH3)applications.
1. Use qualified personnel when installing,operating,
and maintaining these regulators. Before installation
inspect for damage. Make sure there is not any
foreign material in the regulator and all tubing and
piping are clean andunobstructed.
2. If installing the regulator at an outside location,
point the spring case vent in the downwarddirection
to protect it from getting plugged or from collecting
moisture, corrosive chemicals, or other foreign
materials. Spring case vent orientation maybe
changed by rotating the spring case with respect to the
regulator body.
3. Install the regulator so that flow is from the IN to
OUT connection as marked on the regulator body.
! WaRnIng
If using this regulator on hazardous
gas or flammable fluid, make sure
that the vented gas is piped to a safe,
well-ventilated area. Do not install a
regulator so that the gas will be vented
into a closed space. This could result
in a fire or explosion which could cause
personal injury or equipment damage.
4. Toremotely vent the spring case, remove the
screen, if present, and connect 1/4-inch NPT piping
or tubing to the spring case connection. The pipingor
tubing should vent the spring case to a safe location,
have as few bends as possible, and have a screened
vent on its exhaust end that is weather resistant and
always pointed in the downward direction.
5. Like most regulators, 64 Series regulators have
outlet pressure ratings lower than inlet pressure
ratings. Although types with internal relief include
limited downstream overpressure protection, all
types may require additional relief protection for
some service conditions if the actual inlet pressure
can exceed the regulator outlet pressure rating or
the pressure ratings of any downstreamequipment.
Inspect a regulator periodically and after any
overpressure condition.
6. Each regulator is factory-set for the pressure
setting specified on the order. If no setting is specified,
outlet pressure is factory-set at the midrange of the
control spring.
Startup
Key numbers are referenced in Figure 2.
1. Slowly open the upstream and downstream
shutoff valves while monitoring the outlet pressure
with a gauge installed at some point downstream
from the regulator. Pressure may also be monitored
by installing a pressure gauge in the unused
outlet connection.

•Turn the adjusting screw (key 12) whilemonitoring
Disassembly
note
the pressure. Turn clockwise to increase the set
pressure; turn counterclockwise to decrease the
set pressure.
•Tighten the locknut after adjustment ismade.
Shutdown
1. �lose the upstream shutoffvalve.
2. �lose the downstream shutoffvalve.
3. If vent valves are installed, open the vent valve
between the regulator and the downstream shutoff
valve. Then, open the vent valve between the
regulator and the upstream shutoffvalve.
4. If vent valves are not installed, safely bleed off
both inlet and outlet pressures, and check that the
regulator contains nopressure.
Maintenance
Regulator parts are subject to normal wear and mustbe
inspected and replaced as necessary. The frequency
of inspection and replacement of partsdepends
upon the severity of service conditions as well as the
requirements of local, state, and federal regulations.
! WaRnIng
To avoid personal injury or equipment
damage from sudden release of
pressure or explosion of accumulated
gas, do not attempt any maintenance or
disassembly without first isolating the
regulator from system pressure
and relieving all internal pressure from
the regulator.
The body assembly (key 1) may remain
mounted in a line or panel or on other
equipment during disassembly as long
as the entire regulator does not have to
be replaced.
The following procedure describes how to completely
disassemble the regulator. When part replacement
or inspection is required, complete only those steps
necessary to accomplish the task, and then start the
assembly at the appropriate step. Key numbers are
referenced in Figure 2.
1. Remove closing cap (not shown), ifused.
2. Loosen locknut (key 13), and turn adjusting
screw (key 12) counterclockwise so that spring
tension is relieved.
3. Remove the cap screws and nuts (keys 14 and 15)
that hold the spring case (key 2) on the body (key 1).
Then, remove the spring case, regulator spring (key4),
and upper spring seat (key11).
4. Remove the diaphragm assembly (key9).
5. Unscrew and remove the stem guide (key 8) from
the valve body.
6. Remove the stem seal O-ring (key 5) from the
body. If the O-ring is to be replaced, it should be
lubricated.
7. Unscrew the body plug (key 10). This permits
removal of the valve spring (key 3) and the disk holder
assembly (key 6).
Spring Installation
Reassemble in the reverse of the above procedures.
1. Lubricate the upper spring seat and the exposed
threads of the adjusting screw with Anti-Seizelubricant.

2. Position the spring case (key 2) over the spring
and onto the regulator body (key 1). Orient the
spring case vent as necessary.
3. Insert the cap screws and nuts (keys 14 and15),
and tighten them only finger tight.
4. Thread the adjusting screw and locknut (keys 12
and 13) into the spring case just far enough to slightly
compress the spring.
5. Securely tighten the cap screws (key 14), and
refer to the Startup section for adjustmentprocedures.
