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
W1934
Figure 1. Spring-Loaded Type 630 Regulator
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.

MAXIMUM ALLOWABLE INLET
PRESSURE, PSIG (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-inch (9,53 mm) orice with a maximum allowable pressure drop of 500 psid (34,5 bar, differential), the maximum allowable 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 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.

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-inch 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
spring-loaded regulators have outlet pressure
ratings that are lower than the inlet pressure ratings.
Overpressure protection must be provided if the
INLET PRESSURE

Figure 3. Type 630R Relief Valve Operational Schematic
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.
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
over-tightening 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.
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 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.
4
Page 5
630 Series
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
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-inch (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.
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.
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.
9. Be certain the lever (key 14) engages the
valve carrier.
10. Secure the diaphragm adaptor (key 13) to the
body (key 23). Fit the inlet adaptor (key 18) to the
body 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 low-pressure
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.
