630 Series
Installation
WARNING
!
Personal injury, property damage,
equipment damage or leakage due to
escaping gas or bursting of pressurecontaining parts may result if this
regulator is overpressured or is installed
where service conditions could exceed
the limits given in Specications
section, Tables 1 through 3 or where
conditions exceed any ratings of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate
code, regulation or standard) to prevent
service conditions from exceeding
those limits.

Additionally, physical damage to the
regulator could cause personal injury or
property damage due to escaping gas.
To avoid such injury or damage, install
the regulator in a safe location.
Before installing, inspect the unit for any damage and
any foreign material. The regulator or relief valve may
be mounted in any position, however, ensure that the
ow direction corresponds with the direction of the
arrow on the nameplate. Apply a good grade of pipe
compound to the male threads of the pipeline.

Vents
WARNING
!
When the unit is installed in an enclosed
area or indoors, escaping gas may
accumulate and be an explosion hazard.
Under these conditions the vent should
be piped away from the unit to a freely
ventilated outdoor location away from
air intakes, windows, etc. Protect all vent
openings against weather or the entrance
of any foreign material that may plug the
vent or affect operation of the regulator
or relief valve. Inspect all vent openings
periodically to be sure they are not
plugged. If the vent is in an environment
where freezing rain, ice or snow could
clog the vent, it is recommended that a
weatherproof vent be used.
Spring-loaded constructions have a screened vent
assembly (key 27, Figures 4, 5 and 6) installed in the
1/4 NPT spring case vent opening. If a remote vent
is required, remove the vent assembly and install a
remote vent line.
Overpressure Protection
As is the case with most regulators, the Type 630 springloaded regulators have outlet pressure ratings that are
lower than the inlet pressure ratings. Overpressure
protection must be provided if the actual inlet pressure
can exceed the outlet pressure rating. Overpressure
protection is also required for the loading regulator and
main regulator spring case of relief valves.
Refer to the following tables to determine pressure ratings:
1. Spring-loaded Type 630 regulators.
a. Inlet pressure and pressure drop—Table 1.
b. Outlet pressure—Table 2.
2. Spring-loaded Type 630R relief valve pressure
Table 3.
WARNING
!
Overpressuring any portion of this
equipment may cause damage to
regulator parts, leaks in the regulator
or personal injury due to bursting of
pressure-containing parts or explosion
of accumulated gas.

Note: Maximum inlet pressure not exceeded 1500 psig / 103 bar.
1. Inlet pressure must not exceed the sum of the actual outlet pressure setting and the maximum allowable pressure drop. For example, with an outlet pressure setting of 200 psig / 13.8 bar
and a 3/8 in. / 9.5 mm orice with a maximum allowable pressure drop of 500 psid / 34.5 bar d, the maximum inlet pressure is 700 psig / 48.3 bar.
2. Nitrile (NBR) valve disks are normally furnished for pressure drops to 200 psi / 13.8 bar, differential. For better erosion resistance, Nylon (PA) valve disks are normally furnished for
higher
pressure drops. Some erosion of valve disks occurs at all pressure drops due to solid particles in the ow stream. The rate of erosion is higher with large amounts of impurities in the
ow stream and with high pressure drops. Valve disks and other regulator parts must be inspected periodically for erosion and damage and must be replaced as necessary.

To avoid overpressure, provide an
appropriate overpressure protection
device to ensure that none of the limits
listed in Specications section, Tables 1
through 3 will be exceeded.
Regulator or relief valve operation below the limits
specied in Specications section, Tables 1 through 3
does not preclude the possibility of damage from external
sources or from debris in the gas line. Inspect the
regulator for damage after any overpressure condition.

Startup
Starting up the unit consists of opening the upstream
block valve, introducing gas pressure. Use gauges to
monitor pressures during startup.
The range of allowable pressure settings is marked
on the nameplate. If a pressure setting beyond the
nameplate range is required, substitute an appropriate
spring selected from Table 5. Be sure to change the
nameplate to indicate the new pressure range.

WARNING
!
To avoid the consequences of overtightening the spring in spring-loaded
regulators or relief valves, consult
Table 4 and replace the adjusting screw
with one of the correct length when
replacing the spring.
Some pressure ratings are dependent upon the actual
outlet pressure settings being used. For example,
with a Type 630 regulator, outlet pressure must not
exceed the setting by more than 20 psig / 1.38 bar
for low pressure constructions or 200 psig / 13.8 bar
for high pressure constructions or damage to internal
regulator parts may occur. However, with some higher
pressure ranges, the setting plus 20 psig / 1.38 bar or
200 psig / 13.8 bar exceeds the maximum emergency
outlet (casing) pressure. Before increasing the setting,
refer to Tables 2 and 3 (as appropriate). Review the
pressure limits for the spring range being used and
be certain that the new pressure setting will not result
in an overpressure condition. Always use a pressure
gauge to monitor pressure when making adjustments.

Figure 3. Type 630R Relief Valve Operational Schematic
Adjusting Spring-Loaded Regulators
and Relief Valves
Loosen the hex nut (key 2, Figures 4, 5 and 6) atop
the spring case. While monitoring the pressure,
rotate the adjusting screw (key 1, Figures 4, 5 and 6)
clockwise to increase set pressure or counterclockwise
to decrease it. When the unit is regulating or relieving
pressure at the desired value, tighten the hex nut.
Shutdown
Slowly close the upstream block valve.
Principle of Operation
This section describes the operation of the Type 630
regulator and the Type 630R relief valve with spring
loading. Set pressure is changed with the adjusting
screw on the regulator or relief valve. The Type 630R
relief valve uses a light spring for added stability.
Type 630 Regulators
Refer to Figure 2. In the regulator construction, outlet
pressure registers beneath the diaphragm. As long
as the outlet pressure is less than the set pressure,
spring force on the diaphragm causes the lever to hold
4
Page 5
630 Series
the valve open. When the outlet pressure exceeds the
set pressure, the diaphragm moves to compress the
spring and the lever closes the valve until the outlet
pressure returns to set pressure.
Type 630R Relief Valves
Refer to Figure 3. In the relief valve construction, inlet
pressure registers beneath the diaphragm. As long
as the inlet pressure is less than the set pressure,
spring force causes the lever to hold the valve closed.
When the inlet pressure exceeds the set pressure,
the diaphragm moves to compress the spring and the
lever opens the valve allowing inlet pressure to bleed
into the downstream line or to atmosphere until the
inlet pressure returns to set pressure.
Maintenance
Parts are subject to normal wear and must be inspected
and replaced as necessary. Frequency of inspection
depends upon severity of service conditions.
WARNING
!
To avoid personal injury or equipment
damage, isolate the regulator or
relief valve from the pressure system
and release all pressure from the
regulator or relief valve before
performing maintenance.
Except where indicated, key numbers in the following
procedures are shown in Figures 4 and 5 for the
Type 630 regulator, in Figure 6 for the Type 630R
relief valve.
Replacing Orice, Valve Disk and Lever
Note
With some piping systems it may
be possible to omit step 1 below by
removing four cap screws (key 17) and
spreading the body (key 23) and inlet
adaptor (key 18) far enough apart to
allow removal of the orice (key 20)
and Type 630 valve disk (key 21,
Figures 4 and 5) or the orice (key 20)
and the Type 630R valve seat O-ring
(key 37, Figure 6).
CAUTION
If step 1 is omitted and the body and
inlet adaptor are separated, take care to
avoid pinching ngers between the body
and the inlet adaptor.
1. Disconnect piping from inlet adaptor (key 18).
Remove four cap screws (key 17) and adaptor.
2. Remove orice (key 20) and gaskets (key 19).
3. To remove Type 630 valve disk (key 21, Figures 4
and 5) or Type 630R valve seat O-ring (key 37,
Figure 6), rst disconnect remote vent pipe (if one
is used).
4. Unscrew the two cap screws (key 31, not shown)
that secure diaphragm adaptor (key 13) to body
(key 23); remove diaphragm adaptor and attached
spring case (key 3).
5. If it is necessary to replace the lever (key 14),
drive out the pin (key 15) and slide the lever out
of the diaphragm adaptor. When replacing the
lever, make sure the slot engages the connector
assembly (key 12) and replace the pin.
6. Remove valve carrier assembly (key 22)
from body.
7. To replace seating surface:
a. For Type 630, use a 3/4 in. / 19.1 mm socket
wrench to remove and re-install valve disk and
holder assembly (key 21, Figures 4 and 5).
b. For Type 630R, unscrew machine screw (key 36,
Figure 6) and remove O-ring washer and
O-ring (keys 32 and 37, Figure 6) from O-ring
holder (key 21, Figure 6). When reassembling,
apply a good-quality gasket shellac to the
machine screw thread.
8. Use new orice gaskets (key 19) and body
gasket (key 16) when reassembling. Insert valve
carrier assembly (key 22) into the body before
re-installing the diaphragm adaptor.
Note
The spring case (key 3) must point
away from the inlet adaptor (key 18)
on Type 630 regulators as shown in
Figures 4 and 5. On Type 630R relief
valves, the spring case (key 3) must face
the same direction as the inlet adaptor
(key 18) as shown in Figure 6.

and install and tighten the four cap screws (key 17).
Replacing the Diaphragm
1. To relieve spring compression, loosen hex nut
(key 2, Figures 4, 5 and 6). Turn the adjusting
screw (key 1, Figures 4, 5 and 6) counterclockwise
until spring compression is relieved.
2. Disconnect remote vent line (if one is present).
3. Remove spring case (key 3) by unscrewing cap
screws and nuts (keys 9, 10 and 30).
4. Remove diaphragm (key 11) and attached parts
from the lever (key 14).
5. Unscrew cap screw (key 6) from connector
head assembly (key 12) and disassemble the
diaphragm assembly.
6. Install new diaphragm being certain that
the diaphragm is centered. Note that lowpressure constructions use a diaphragm plate
(key 8, Figure 5) on the spring case side of
the diaphragm. Install new gaskets when
replacing diaphragm.
7. When reassembling, be certain that the diaphragm
connector is engaged in the lever.
Note
Be careful not to twist the diaphragm
to lever attachment during assembly.
Twisting will cause sufcient friction to
interfere with the proper operation of
