CVS Controls Series 627
Pressure Regulator
The CVS Series 627 regulator is a high and
low pressure, direct operated pressure
reducing regulator. Suitable for use in many
applications, including air, natural gas and
other fuel gas sources.
CVS Series 627 Regulators are easy to
maintain, reducing cost of ownership and
valuable downtime. Internal components
may be replaced without the need to
remove the regulator from the applications
installation. The two bolt design between
the body and diaphragm case allows for
simple removal to do maintenance or
repairs.
The diaphragm case and or the regulator
body may be rotated in any of four
positions to allow for versatile installation
options.
The adjustment set screw and lock nut
come standard with a protective cap to
discourage unwanted adjustments of the
desired pressure output.
Three configurations available:
CVS 627 - Direct Operated Pressure
Reducing
CVS627R – Internal relief
CVS627H – High Pressure
All are sour or NACE capable.

Installation:
Note: Do not exceed the pressure and temperature limits referenced in this manual. Ensure
proper safety procedures are followed when installing or maintenance is required. Only
qualified personnel should install, operate and maintain this component.
1. If the CVS 627 regulator has been shipped as an individual component, inspect for debris
or foreign materials upon un-packaging.
2. Ensure all piping and tubing connections are free of debris and have been blown free.
3. The 627 Regulator may be installed in any direction, as long as the flow direction is
adhered to as marked on the body.
4. A three-way valve may be utilized should continued operation be required during
inspection and maintenance procedures. (not supplied)
5. Position the body and diaphragm spring case in a manner that prevents the screened
vent from collecting debris or moisture.
Note: This regulator may ventilate some gas to atmosphere. If installed in a hazardous or
flammable gas application, ensure proper venting procedures are followed. Vent the
regulator to a safe location away from any hazardous area. Keep the vent line clear of debris
and or condensation.
Remote Venting Installation:
The CVS Series 627 Regulator comes standard with a screened vent installed in the 3/4" NPT
spring case vent. When necessary to remotely vent the regulator the screened vent may be
removed to install a remote vent line.
Always ensure the remote vent line is installed using proper piping procedures. Keep the vent
line free of debris and or any condensation, and periodically inspect the vent line for proper
regulator operation.
Overpressure Protection:
The outlet pressure rating on the Series 627 Regulator is lower than the inlet pressure rating. If
the inlet pressure exceeds the outlet pressure on the CVS 627H, a pressure limiting or pressure
relieving device must be installed as there is no internal relief. Internal damage may occur if this
step is not followed.
4 | P a g e
Startup and Adjustments:
The CVS Series 627 Regulator is set to the midpoint of the spring range upon assembly, unless
otherwise specified by the customer. Initial adjustments may be required at point of installation
to suit the application.
During startup, release downstream pressure to prevent an overpressure condition. It is
recommended pressure gauges be utilized to monitor pressures during startup.
1. Open upstream shutoff valve slowly.
2. Open downstream shutoff valve slowly.
3. Inspect all connections for leaks.
4. Should any final control spring adjustments be needed refer to the Adjustment portion
of this manual.
Adjustments:
1. Remove the Adjustment Screw Cap.
2. Loosen the Adjustment Screw Lock Nut.
3. It is recommended a pressure gauge be used when making final adjustments to the
regulator.
4. To increase the CVS 627 Regulator outlet pressure, turn the adjustment screw clockwise.
To decrease the outlet pressure, turn the adjustment screw counter clockwise.
5. Once the final pressure has been achieved, while holding the adjustment screw, tighten
the adjustment screw locknut.
6. Replace the adjustment screw cap that was removed in step 1.
5 | P a g e
Shutdown and Maintenance:
Shutdown:
Avoid an overpressure condition on the regulator by first releasing downstream pressure to
avoid equipment damage or personal injury.
1. Close upstream shut off valve.
2. Close downstream shut off valve.
3. Vent line between the regulator installation and the closest downstream shut off valve.
4. The CVS 627H Regulator will open to release the pressure between the upstream shut
off valve and the regulator.
Maintenance:
Always follow proper shutdown procedures prior to performing any maintenance. Isolate the
regulator from all system pressure to avoid personal injury and/or equipment damage.
Periodic inspections of the CVS 627 regulator are recommended, and field maintenance may be
required should the inspection reveal damaged or worn parts due to normal operation, or
damage from external sources. Severe operating conditions may require more frequent
inspections.
Common items to inspect for wear or damage include the orifice, disk assembly, diaphragm,
and o-rings. These procedures may also be used to inspect and replace other regulator items as
required.
