CVS Type 630 HP
Regulators and
Relief Valves
Introduction
Please note: These regulators and relief valves must
be installed, operated and maintained in accordance
with CVS instructions and all applicable federal,
provincial, state and local codes, laws, rules, and
regulations.
The CVS 630 HP Series consists of a high pressure
reducing regulator, and Type CVS 630R relief valve.
These regulators and relief valves are furnished in
either spring-loaded or pressure-loaded construction
with 1 or 2 inch NPT screwed end connections and
ASME Class 150 through 600 RF Flanged end
connections.
Pressure loaded Type 630 HP regulators are
normally furnished without a main regulator spring
and use a Bellofram 7360 or a Bellofram P39
regulator.
Pressure loaded Type 630R relief valves are
furnished with a light rate relief valve spring and use
a Bellofram 7360 or a Bellofram P39 regulator.
Installation
After uncrating the regulator or relief valve, inspect it
for shipping damage. Be certain the body cavity and
seat ring are free from any foreign material. Also be
certain that connecting pipelines are free of loose
pipe scale.
The regulator or relief valve may be installed in any
position, but direction of flow through the body must

be as indicated by the flow direction arrow on
nameplate.
Note that in diagrams in this manual, regulator flow
direction is opposite relief valve flow direction.
Protect the regulator or relief valve against damage
from vehicles and other external sources. The
temperature capability of the 630 HP Series
regulator and relief valves with standard construction
materials is –20 to +150F, optional construction -20
to 300oF.

Vents
Spring-loaded constructions have a screened vent
assembly (Key 24) installed in the ¼” NPT spring
case vent opening. If a remote vent is required,
remove the vent assembly and install a remote vent
line.
Pressure loaded constructions have a bleed orifice
fitting (Key 38) installed in an extra outlet connection
of the loading regulator. The function of this fitting is
to bleed loading pressure during operation of the
regulator or relief valve.
Warning: The bleed orifice fitting
continuously vents a small amount of gas. If
the regulator or relief valve is located where
accumulation of the vented gas will create
an explosion hazard, install a remote vent
line to carry the vented gas to a safe area.
The bleed orifice is furnished with a ¼” NPT
screened opening; remove the screen and
install remote vent line.
All remote vent lines must have as large an inside
diameter as possible. The vent line should be as
short as possible with a minimum number of bends
and elbows. Protect all vent openings against
entrance of rain, snow or any other 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.
Overpressure Protection
As is the case with most regulators, the Type 630 HP
spring-loaded and pressure-loaded 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 may
also be required for the loading regulator and main
regulator spring case of pressure loaded regulators
and relief valves.
Refer to the following tables to determine pressure
ratings:
1. Spring loaded Type 630 HP regulators
1.1. Inlet pressure and pressure drop (Table 1)
1.2. Outlet pressure (Table 2)
2. Pressure loaded Type 630 HP regulators
2.1. Main regulator inlet pressure and pressure
drop (Table 1)
2.2. Loading pressure and outlet pressure
(Table 3)
3. Spring loaded Type 630R relief valve pressure
(Table 4)
4. Pressure loaded Type 630R relief valve
pressures (Table 5)
WARNING: Over pressuring any portion of this
equipment may cause damage to regular parts,
leaks in the regulator or personal injury due to
bursting of pressure-containing parts or
explosion of accumulated gas.
To prevent overpressure, provide an appropriate
overpressure protection device to ensure that none
of the limits listed in tables 1 through 5 will be
exceeded.
Regulator or relief valve operation below the limits
specified in tables 1 through 5 does not preclude the
possibility of damage from external sources or from
debris in the gas line. Inspect the regulator for
damage following any over pressuring condition.
Loading Regulator Supply Pressure
Use a clean, dry gas as supply pressure for the
loading regulator of pressure loaded regulators or
relief valves. Connect the supply to the ¼” NPT inlet
connection of the loading regulator. The supply
pressure may be obtained from the upstream piping,
but be certain adequate overpressure protection is
provided for the loading regulator and for the spring
case of the main regulator or relief valve.

Does not apply to loading regulator of pressure-loaded Type 630 HP.
+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 and a 3/8” port dia. (maximum allowable pressure drop of 500 psig), the maximum allowable inlet pressure is 700 psig.
++ Nitrile valve discs are normally furnished for pressure drops to 200 psi. For better erosion resistance, nylon valve discs are normally furnished for
higher-pressure drops.
Some erosion of valve discs occurs at all pressure drops due to solid particles in the flow stream. The rate of erosion is higher with large amounts of
impurities in the flow stream and with higher pressure drops. Valve discs and other regulator parts must be inspected periodically for erosion and
damage and must be replaced as necessary.

Putting Unit in Service
Use pressure gauges to monitor pressure during
startup.
1. For pressure loaded constructions, turn on
supply pressure to loading regulator.
2. Slowly open upstream shutoff valve.
3. Slowly open the downstream shutoff valve.
4. Check all connections for leaks.
5. If indicated by the monitoring pressure gauges,
make final spring adjustments per the
“Adjustment” section.
Adjustment
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 in the relief valve or loading
regulator. Be sure to change the nameplate to
indicate the new pressure range.
Some pressure ratings are dependent upon the
actual outlet pressure settings being used. For
example, with a Type 630 HP regulator, outlet
pressure must not exceed the setting by more than
20 psig (200 psig for high-pressure constructions), or
damage to internal regulator parts may occur.
However, with some higher-pressure ranges, the
setting plus 20 psig (200 psig for high-pressure
constructions) exceeds the maximum emergency
outlet (casing) pressure. In these cases, outlet
pressure must be limited by the maximum
emergency outlet (casing) pressure. Before
increasing the setting, refer to table 2 through 5 (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.
Spring Loaded Regulators and Relief
Valves
1. Loosen locknut (Key 22)
2. Rotate the adjusting screw (Key 23) clockwise
to increase the setting or counter clockwise to
decrease the setting.
3. Tighten locknut.
Pressure Loaded Regulators and Relief
Valves
1. Loosen the locknut found on the loading
regulator adjusting screw.
2. Rotate the loading regulator adjusting screw
clockwise to increase the setting or
counterclockwise to decrease the setting.
3. Tighten locknut.
Taking out of Service
Isolate the regulator or relief valve from all pressure.
For pressure loaded constructions, shut off supply
pressure to loading regulator.
Cautiously vent all pressure from the regulator or
relief valve before performing any service on the
unit.

Maintenance
WARNING: To avoid personal injury and
equipment damage, isolate the regulator or
relief valve from all pressure. Cautiously
release pressure from the regulator or relief
valve before attempting disassembly.
Due to normal wear that may occur in regulators and
relief valves, parts such as the valve disc, seat ring
and diaphragm must be inspected periodically and
replaced as necessary. The frequency of inspection
and replacement depends upon the severity of
service conditions or federal and provincial laws.
Normal wear of the seat ring and valve disc is
accelerated with high-pressure drops and with large
amounts of impurities in the flow stream.
Instructions are given below for replacing the seat
ring, valve disc and diaphragm. These instructions
may also be used for disassembly required for
inspection and replacement of other parts.
If the loading regulator of pressure-loaded
constructions requires maintenance, disconnect the
supply pressure line (and bleed orifice vent line if
one is present) and unscrew the loading regulator
from its mounting nipple. Refer to the separate
instruction manual for maintenance information.
Seat Ring and Valve Disc:
Note: With some piping systems it may be
possible to omit step 1 below by removing
four cap screws (Key 7) and spreading the
body (Key 1) and adaptor (Key 6) far
enough apart to allow removal of the seat
ring (Key 4) and Type 630 HP valve disc
(Key 3) or Type 630R valve seat O-ring
(Key 32). However, take care to avoid
pinching fingers between body and adapter.
1. Disconnect piping from Adapter (Key 6).
Remove four cap screws (Key 7) and adapter.
2. Remove seat ring (Key 4) and gaskets (Key 5).
3. To remove Type 630 HP valve disc (Key 3) OR
Type 630R valve seat O-ring (Key 32), first
disconnect remote vent pipe (if one is used).
For pressure loaded constructions, disconnect
loading regulator supply line.
4. Unscrew the two cap screws that secure
the diaphragm adaptor (Key 11) to body
(Key 1); remove diaphragm adaptor and
attach spring case (Key 21).
5. Remove valve carrier assembly (Key 2)
from body.
6. To replace seating surface:
6.1. For Type 630 HP, use a ¾” socket
wrench to remove and re-install valve
disc and holder assembly (Key 3).
6.2. For Type 630R, unscrew machine
screw (key31) and remove O-ring
washer and O-ring (Key 28 and 32)
from O-ring holder (Key 3). When
reassembling, apply a good quality
gasket shellac to the machine screw
thread.
7. Use new seat ring gaskets (Key 5) and
body gasket (Key 8) when reassembling.
Insert valve carrier assembly (Key 2) into
the body before re-installing the
diaphragm adaptor.
8. The spring case (Key 21) must point away from
the adaptor (Key 6) on Type 630 HP regulators.
On Type 630R relief valves, the spring case
must face the same direction as the adaptor
(Key 6). Be certain the lever (Key 10) engages
the valve carrier.
Diaphragm
1. Relieve spring compression as follows:
1.1 For spring loaded constructions, loosen
locknut (Key 22). Turn the adjusting screw
(Key 23) counterclockwise until spring
compression is relieved.
1.2 For pressure loaded Type 630R relief valves
(and for pressure loaded Type 630 HP
regulators that have been furnished with a
spring), turn cap screw (Key 23)
counterclockwise until spring compression is
relieved.
2. Disconnect remote vent line (if one is present).
3. For pressure loaded constructions, disconnect
the supply line from the loading regulator (Key
25).
4. Remove spring case (Key 21) by unscrewing
cap screws and nuts (Key 14).
5. Remove diaphragm (Key 13) and attached parts
from lever assembly (Key 10).
6. Unscrew cap screw (Key 18) from connector
head assembly (Key 12) and disassemble the
diaphragm assembly.
7. Install new diaphragm. Note that low-pressure
constructions use a diaphragm plate (Key 16)
on the spring case side of the diaphragm. Low
pressure, pressure loaded constructions use a
diaphragm plate on each side of the diaphragm
plate gasket (Key 33) with each plate. Install
new gaskets when replacing diaphragm.
8. When reassembling, be certain that the
diaphragm connector is engaged on the lever.

6
9. To ensure proper slack in the diaphragm:
9.1 For constructions using a spring, tighten the
spring case cap screws finger tight only.
Compress the spring slightly with the
adjusting screw (or cap screw for pressure
loaded constructions); then complete the
tightening of spring case cap screws and
nuts.
9.2 For constructions without a spring, tighten
spring case cap screws finger tight only.
Remove cap screw (Key 23). Insert a rod in
the spring case and push on the assembly to
take up the slack; then complete the
tightening of the spring case cap screws.
Re-install cap screw (Key 23) in spring case.
