T.............Higher ambient temperature range.

V ............Threaded vent connector, 5/16-24 for 1/8” tubing connection (RV20) - with dust cap.

* Short stack models have an adjustment range of less than 2” w.c. (0.5 kPa); these models are advantageous

where installation must be made in a limited space.

** CV47 is best described as a RV47 with an extra regulated outlet. This outlet contains an integral manual valve

located on the valve body’s side.

*** Convertible regulators are designed to deliver either of two xed outlet pressures for natural or LP gases.

RV20C: NAT GAS: 4.0” w.c. (1.0 kPa); LP: 10” w.c. (2.5 kPa) RV47C, RV48C, CV47C: NAT GAS: 4.0”, 5.0” or 6.0” w.c. (1.0, 1.3, or 1.5 kPa); LP: 10” or 11” w.c. (2.5 or

2.8 kPa)

+ Left and right is determined when viewing regulator from outlet side with stack up.

NOTE: The RV48 model may be used with either a 12A04 ball check device, or a 12A06 xed orice vent limiting device.

Straight-Thru-Flow Design

Maxitrol’s original straight-thru-ow (STF) design regulators

are non-lockup type regulators for high capacities at low inlet pressures. The difference between STF design and other type regulators is the conical valve. The cone principal permits gas to

ow straight through the regulator without changing directions. Frictional ow resistance is reduced, resulting in greater capacity. An improved ow pattern provides accurate, sensitive

regulation at extremely low pressure differentials. Typical applications include residential, commercial, and industrial

gas-red appliances and equipment used on low or medium

pressure gas supplies.

R/RS SERIES

Balanced Valve Design

The R & RS series’ double diaphragm balanced valve design

makes it possible to maintain steady outlet pressure control

with widely varying inlet pressures. The regulator is physically

small yet has exceptional capacity characteristics. R & RS series

regulators are intended for use with both main burner and pilot

load applications. They are ideally suited for use with infrared

heaters and pilot lines on large industrial heaters and boilers.

210 SERIES

Balanced Valve Design

The 210 series is a lockup type regulator. The balanced valve

design makes it possible to maintain steady outlet pressure

control with widely varying inlet pressures. The regulator has

an integrated dampening mechanism in the breather outlet

and the sensing tube to improve regulating stability and reduce

hunting tendencies. The 210 series provides precise regulation

over a wide range of pressures and ow rates. Applications

include gas-red boilers, steam generators, industrial furnaces,

and ovens.

RZ and 210Z

Zero Governor Design

Both the RZ and 210Z series are adaptable for air-gas mixing

applications. Because of the balanced valve construction,

Z-models offer superior performance at an economical price

compared with other types of atmospheric regulators.

Maxitrol’s RZ and 210Z Zero Governor model regulators are

used for ow control of burners, nozzel mixers, mixing tees and

proportional premixers.

220 SERIES

Pilot Loaded Design

The 220 series uses a servo-operated design rather than a

spring-loaded design and can deliver higher outlet pressures

than conventional spring-loaded models.

The main diaphragm of the model 220 is loaded with gas pressure

instead of spring pressure. A small pilot regulator, located in the

upper housing, accurately controls this gas pressure. When the

regulated outlet pressure of the servo regulator is changed by

spring adjustment, the outlet pressure of the 220 main regulator

will be changed proportionately. Applications include industrial

furnaces and ovens.

SIZING A REGULATOR

See www.maxitrol.com for our Regulator Sizing Program. Please contact Maxitrol directly for more information on sizing a regulator.

System Requirements

When sizing a regulator the following must be known:

• Gas Type

• Available Inlet Pressure

• Desired Outlet Pressure

• Zero Governor Application (indicated by model number ending in “Z”)

• Will the regulator control main burner and pilot load OR main burner only?

• Required minimum and maximum ow rate in cfh or m3/h or Btu/h

• Pipe Size

In most cases, the manifold pipe size has already been selected on the basis of good engineering practice, and the regulator pipe size should conform to this size.

The capacity of any regulator is not an absolute value but will vary with the application depending on the prevailing differential pressure.

Service and installation must be performed by a trained/experienced service technician.

All products used with combustible gas must be installed and used strictly in accordance with the instructions of the Original Equipment Manufacturer (OEM) and with all applicable government codes and regulations, e.g. plumbing, mechanical, and electrical codes and practices. These instructions do NOT supersede OEM’s installation or operating instructions.

All Maxitrol products should be installed and operated in accordance with Maxitrol Safety Warning Instructions.

HOW TO CALCULATE PRESSURE DROP AT VARIOUS FLOW RATES FROM CAPACITY CHART

LP Applications - When using natural gas pressure drop chart to determine LP pressure drop in terms of Btu/h, multiply NAT

Btu/h by 1.61; in terms of CFH multiply NAT CFH by 0.645.

Formula: P2 = P1 x (Q2/Q1)

P2 = Pressure drop at desired ow rate Q2 = Desired ow rate P1 = Known pressure drop Q1 = Known ow rate

A. Check Capacity Chart, insuring regulator has ample range B. Know the minimum encountered inlet pressure. of regulation and individual load capacities (for use with pilot) MINIMUM INLET PRESSURE MINUS “P2” MUST for the application. BE GREATER THAN DESIRED OUTLET PRESSURE. Solve for “P2” using the formula above. (See examples on page 59.)

SIZING A REGULATOR

Sizing Examples

RUBBER SEAT POPPETS

For main burner and pilot load applications.

Example: To select an RV type regulator:

• Known: Single 150,000 Btu/h main burner; pipe size 1/2”; inlet pressure 7” w.c.; outlet pressure 4” w.c.

• Solution: The RV48 (1/2”) has a maximum capacity of 230,000 Bth/h and a maximum individual load of

160,000 Btu/h. The pressure drop at a ow rate of 150,000 Btu/h is 0.4” w.c., well below the available differential of 3” w.c. The RV48 (without “L” xed orice) is the correct regulator to use for the application.

STRAIGHT-THRU-FLOW (S-T-F)

For main burner only applications not requiring a lockup type regulator. When sizing the S-T-F Series, it is recommended that pressure drop not exceed 1/2 of available differential pressure.

Example: To select an RV type regulator:

• Known: Flow rate 2,000,000 Btu/h; pipe size 1 1/4”; inlet pressure 9” w.c.; outlet pressure 5” w.c.

• Solution: The RV81(1 1/4”) has a maximum capacity of 2,500,000 Btu/h. The pressure drop at a ow of

2,000,000 Btu/h is 0.66” w.c. The RV81 (1 1/4”) is the correct regulator to use with this application. The pressure drop of the RV61 (1 1/4”) at a ow rate of 2,000,000 Btu/h is 2.64” w.c. This is within the available differential but exceeds the recommended 50% maximum.

LEVER ACTING

For main burner and pilot load application requiring positive dead-end lockup (see Denitions page 63).

Example: To select a 325 Series regulator:

• Known: Single 145,000 Btu/h burner; pipe size 1/2”; inlet pressure 2 psi; outlet pressure 7” w.c.

• Solution: The 325-3’s pressure drop at a ow rate of 145,000 Btu/h is 7” w.c., well below the available

differential of 1 3/4 psi. The 325-3 (1/2”) is the correct regulator to use with this application.

BALANCED VALVE

For main burner and pilot load application requiring a lockup type regulator or zero governor usage (see Denitions page 63).

Example: To select a 210 or R/RS Series regulator:

• Known: Desired ow rate 6,000,000 Btu/h; pipe size 1 1/2”; inlet pressure 1 psi; outlet pressure 9” w.c.

• Solution: The 210E (1 1/2”) has a maximum capacity of 10,000,000 Btu/h. The 210D (1 1/2”) has a capacity of 6,000,000 Btu/h. Therefore, the 210E (1 1/2”) will give you the desired outlet pressure of 9” w.c. and is the correct regulator to use for the application.

DEFINITIONS

Dead End Lockup

Pressure will be maintained within ANSI/CSA limits under

no ow conditions. The amount of climb above set point is inuenced by inlet pressure, ow rate before no ow

condition and piping arrangement. Dead end lockup pressure regulators must be properly sized for desired performance.

Differential Pressure

The difference between inlet pressure to the pressure regulator and outlet pressure from the pressure regulator. To obtain differential pressure, subtract the desired outlet pressure from available inlet pressure.

Line Pressure Regulator

A pressure regulator intended for installation in a building gas distribution system between the building service regulator or LP-gas 2 psi service regulator and gas utilization equipment.

Lockup Type

Under no ow conditions, outlet pressure will rise above

adjusted pressure but will not rise to line pressure.

Minimum Capacity (Main Burner Only

Minimum capacity of a pressure regulator designed to

control the ow to the main burner only.

Maximum Capacity (Main Burner Only

Maximum capacity of a pressure regulator at which the pressure regulator will control main burner pressure within acceptable limits.

Maximum Capacity (Main Burner and Pilot

Maximum capacity of a pressure regulator at which the pressure regulator will control main burner and pilot line pressure within acceptable limits.

)

Non-Lockup Type

Under static conditions when no gas is owing, outlet

pressure will rise to line pressure.

Overpressure Protection Device (OPD

A device which under abnormal conditions will act to reduce,

restrict, or shut off the supply of gas owing into a system

to prevent pressure in that system from exceeding 2 psi.

• Monitoring Regulator: An overpressure protection device which functions as a second pressure regulator in series with the primary pressure regulator.

• Overpressure Relief Device: An overpressure protection

device which functions by discharging gas from the downstream system to a safe location.

• Overpressure Shut-Off Device: An overpressure protection

device which functions by completely shutting off the

ow of gas into the downstream system.

)

Pressure Drop

The natural loss of pressure that occurs in the pressure regulator (or in any valve or pipe) due to friction. This

friction impedes uid motion, without regard to articial

losses deliberately created by diaphragm action. The

equivalent ow rate for a loss in given pressure with the

pressure regulator valve in a normally wide open position.

Rated Inlet Pressure

The highest inlet pressure for which the control is intended to be used.

Vent Limiter

A means that limits the ow of gas from the atmospheric

chamber to the atmosphere in the event of a diaphragm

rupture. This may be either a limiting orice or a ball check

vent limiting device.

• Limiting Orice Type: A vent limiter where the ow

through the limiter is the same in both directions

Capacity

Total load Btu/h of all appliances combined.

Maximum Individual Load

Largest single appliance or burner served by the pressure regulator.

Maximum Individual Load Capacity

1. The maximum capacity or ow at which a line pressure

regulator will control lockup pressure within acceptable limits.

2. The maximum capacity or ow at which a pressure

regulator will control pilot line pressure within acceptable limits.

Zero Governors

They require an external impulse signal, such as top loading with pressure or generating vacuum in the downstream piping.
