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.

2. If it is necessary to adjust theregulator:

•Loosen the locknut (key13).

•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

�lose the upstream shutoffvalve.

�lose the downstream shutoffvalve.

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.

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.
