Description:
RP Series Regulator Pilots are reversible pressure control regulator devices designed for use in conjunction with pilot-
operated regulators bodies manufactured by others. They can be used for pressure reducing, backpressure or relief type
applications. The RP Series Regulator Pilots are designed for Gas applications and provide a higher performance than
other “standard-issue regulator pilots.
RP Series Regulator Pilots are available with three (3) differently sized sensing diaphragms that are suited for different
applications based upon the maximum sensing pressure applied and the desired setpoint pressure to be achieved. See
Table 3.0 for additional information.
RP Series Regulator Pilots utilize an internal seat & nozzle internal loading configuration as noted by the characters “SN”
in the model number derivation. Internal nozzles are available in 3/32 in dia. and 1/8 in dia. sizes. The internal nozzles
may be interchanged to achieve required performance based upon application criteria. Standard issue internal nozzle is
3/32 in dia which is suitable for typical “pipeline applications.” For “close-coupled” applications such as power plant fuel
gas feed and 2-stage pressure cut, a 1/8 in dia. internal nozzle should be installed. When utilizing a 1/8 in internal nozzle
a “L” Adjustable Orifice is required.
RP Series Regulator Pilots are available with two (2) different sensing chamber configurations. The “CS” closed spring
sensing chamber design features a design that minimizes forces applied to the pilot internal mechanism and exhibits the
optimum control accuracy, sensitivity and stability. Furthermore the “CS” closed spring sensing chamber encapsulates
the control spring within the process media eliminating exposure to the local atmosphere and protecting it from corrosive
environments. The “OS” open spring sensing chamber provides high performance control accuracy at a reduced price
with fewer parts.
RP Series Pilots parts are interchangeable across model numbers and even across some product series in the VRG
products lines. This interchangeability facilitates understanding of maintenance and operation and may benefit operators
in the field in the event that parts may be needed on an immediate basis for conversion of models and/or repair. All RP
Series Pilots feature body construction with VRG Military Grade Aluminum Alloy with “Stealth System” Corrosion Protection
materials and 316 Stainless Steel to ensure durability and long life in even the most corrosive environments.
The RP Series Regulator Pilot features a manifolded integral Adjustable Orifice installed on the INLET side of the device.
Three (3) different sizes of Adjustable Orifices are available (S, M, and L) to adapt to different operating scenarios and
ensure optimal performance. For “close-coupled” applications such as power plant fuel gas feed and 2-stage pressure
cut, a 1/8 in dia. internal nozzle should be installed. When utilizing a 1/8 in internal nozzle a “L” Adjustable Orifice is
required.
RP Pilots are available in two (2) different Actions: Normally Open (NO) & Normally Closed (NC). Normally Open (NO) is
the standard issue product from VRG Controls and is commonly utilized for Pressure Reduction and Monitor
Overpressure applications. Reference the “RP Model Number Identification Label” on the body of the RP Regulator Pilot
to confirm the Action of the pilot. Note that all RP Regulator Pilots may be field-converted from Normally Open (NO) to
Normally Closed (NC) and vice-versa without the need for any additional parts. If an RP unit action is changed, we
recommend that you obtain a new “RP Model Number Identification Label” in order to display the proper action.

RP Series Regulator Pilot
Installation, Operations, Maintenance - IOM
Installation:
ATTENTION:
Personal injury, damage, or explosion due to leakage of accumulated gas, or rupture of pressurized
components could result if this pilot is overpressured or is installed where operating parameters could exceed
the design limits as indicated in this manual, or where parameters exceed the ratings of the regulator body,
adjacent piping or piping components & fittings. Verify the pressure limitations of pilot and the regulator on
which it is installed to ensure neither device is overpressured. To avoid injury or damage to property, incorporate relief
valves or pressure limiting devices to prevent operating parameters from exceeding required limits. Reference U.S. code
of Federal Regulations, by the National Fire Codes of the National Fire Protection Association, or by other applicable
codes or codes mandated by the operating company as needed.
WARNING
Regulator Pilots and Pilot Operated Regulators installed in enclosed or confined spaces should be provided
with adequate ventilation to prevent the potential of gas accumulation from leakage or venting. Leakage and
vent gas can accumulate causing property damage, severe injury or death. Atmospheric vent ports should be
vented to a safe area away from air intakes, or any hazardous location.
PERSONNEL: Installation of RP Series Regulator Pilots and other manufacture’s Pilot Operated Regulator
Bodies should be performed by qualified personnel that are familiar with high pressure natural gas piping and regulator
technologies.
INSPECTION: Inspect the RP Series Pilot for damage that might have occurred in shipping and handling. Do NOT use
any product that has any remote semblance of damage. Care should also be taken to ensure that no damage exists on
previously installed products that may have been installed at previous locations. If the origin or operational capability of
any product is suspect or unknown, we recommend confirmation of fitness for service by a qualified technician or by VRG
Controls.
ACTION: Inspect the RP Model Number Identification Label AND the Body of the RP Series Pilot to ensure that the unit
has the appropriate ACTION for the desired application. Figures XX and Table XX provide necessary information to
confirm RP Series Pilot Action.
INSTALLATION ORIENTATION: RP Series Regulator Pilots may be installed in any orientation. However, for optimum
results and ease of maintenance, it is typically receommended to install RP Series Pilots in a vertical orientation with the
RP Series Setpoint Adjustment Screw pointing upward.
PILOT MOUNTING: The RP Series Pilot may be installed utilizing a convenient mounting bracket available from VRG
Controls. The RP Pilot may be wall mounted or 2.0 in pipe mounted.
PIPING: Appropriate pipe thread seal tape should be applied to all fittings installed on the RP Pilot. Use of pipe dope is
also encouraged to minimize potential for galling or damage to threaded connections. All threaded connection on the RP
Pilot are ¼ in FNPT.
PILOT SUPPLY LINES: 3/8in stainless steel tubing or ¼ in diameter threaded, non-restricted connections should be
utilized to make connections to the RP Series Pilot. The INLET connection should be made with restrictions in the piping
components. In the event that an isolation valve is installed in the INLET connection, it should be a full-opening type
without restriction.
FILTRATION: Most gas pipeline applications do not require a filter on the INLET connection. If the application may
exhibit dirty gas, an appropriate filter should be applied upstream of the INLET connection to prevent clogging of the
ADJUSTABLE ORIFICE. The filter should be application appropriate with adequate capacity with filtration to 10μ.
PILOT DISCHARGE (OUT): 3/8in stainless steel tubing or ¼ in diameter threaded, non-restricted connections should be
utilized to make connections to the RP Series Pilot. The OUT connection should be made with restrictions in the piping
components. In the event that an isolation valve is installed in the OUT connection, it should be a full-opening type
without restriction.
PILOT GAS PRE-HEATERS: Pilot INLET gas may be heated to prevent excessive refrigeration effects and potential
formation of ice or hydrates in the system. Pilot INLET gas heaters should be connected after the pilot filter upstream of

the INLET port. Note that Pilot pre-heaters are NOT REQUIRED and may be considered per application when large
pressure drops result in severe refrigeration effects.
SENSING LINES: Sensing Lines should be run from the Sensing Port of the RP Series Regulator Pilot to a point roughly
10 pipe diameters from the outlet of the pilot-operated regulator body. See table below for recommended piping
configurations for Sensing Lines. Reduce as necessary to connect to the ¼ in FNPT ports on the RP Series Regulator
Pilot. The Sensing Line connection should be avoid turbulent areas (valves, reducers, and elbows) and should have a full
bore opening to the pipe. Isolation valves are typically recommended on the Sensing Line(s) and should be non-restricted,
full opening type.

Maintenance
Regulator and control device parts utilized in gas regulation applications are subject to normal wear and should be
inspected and replaced as necessary. The frequency of inspection and replacement of parts depends on severity of
service conditions and/or the requirements of local, state, federal regulations. You should consult your company
standards and regulations to determine protocol for maintenance on your equipment. It is critical to ensure that the RP
Model Number Identification Labels, RP Spring Control Range Labels, and other applicable labels are updated and
maintained to ensure legibility and accurately reflect the operation limitations of the device.
WARNING
Before removal, disassembly, or initiating maintenance ensure that the RP Series Regulator Pilot and the Pilot-
Operated Regulator on which it is installed have been isolated from the process. All pressurized gas must be
safely vented from the RP and Regulator System. Failure to relieve all pressure from the system may result in
property damage, severe injury or death.
Applications:
The RP Series Regulator Pilot is designed to provide self-contained pressure control when incorporated with pilot-
operated regulators. The system utilizes pressurized natural gas or from the pipeline to operate and can address a
number of common pipeline pressure control applications. Contact VRG Controls for assistance with your application.
