INTRODUCTION

To evaluate which valve will satisfy your needs, it is necessary to

determinetheapplication.Therst,andmostbasicbreakdown,is

directversusindirectredappliances.

Direct red units do not have a heat exchanger and all products

of combustion generated by the gas burning device are released

directly into the airstream being heated. They are commonly used

in space heating or make-up air applications, process drying, and

baking ovens.

Directredburnershaverawgasinjectedintotheburnerandthe

burner relies entirely on the air being pulled across the burner for

combustion air. It may take advantage of the mixing effects of the

blower by using a pull through system which locates the burner

on the suction side of the blower. This means the air being pulled

across the burner is at a negative pressure (usually not greater than

-1.5”w.c.).Otherdirectredapplicationsmayuseapush through

system, which locates the burner downstream from the blower.

This means the air being pushed across the burner is at a positive

pressure(usuallynotgreaterthan3”w.c.).

Directredburnerscanbeofextremelyhighturndownratios,in

some instances, 30:1. The high turn down ratio allows the minimum

temperature rise to be low enough that the unit does not have to be

cycled on and off to maintain temperature.

Indirect red appliances use a heat exchanger and all products

of combustion generated by the gas burning device are vented

outdoors. They are usually supplied with an atmospheric burner or

a power burner.

With an atmospheric burner, the air being supplied to the burner

is at atmospheric pressure. They have limited turndown ratios

(maximum input: minimum input) of usually 3:1 or 4:1. Due to the

limited turndown ratio, the minimum temperature rise cannot be

held low enough, and as a result, the main gas valve must usually

be cycled to maintain temperature.

A power burner is a burner in which either the gas, air, or both

are supplied at pressures exceeding line pressure for gas and

atmospheric pressure for air. Maintaining the proper gas-air mixture

for modulation usually requires pressure control of both the air and

gas. Burners of this type are usually not capable of modulation with

the Maxitrol Selectra® system. (See Exa Star modulating valves or

ratio (zero) regulators for these applications.)

DIRECT FIRED

Valves designed for direct red applications (negative

pressure/pull through) M411, M511, M611, MR212D, MR212E,

MR212G, and MR212J.

These valves are designed exclusively for negative pressure (pull

through) applications. They use a counter spring to keep the valve in

the closed position despite the downward pull of negative pressure.

M411,M511, and M611valves are setfor applications upto 1.5”

w.c.andarenotadjustable.MR212valvesarefactorysetforap-

plicationsupto-1.5”w.c.andareeldadjustableforupto-3.5”w.c.

M/MR Series Literature

With the main valve closed, an adjustable bypass provides a

minimumringratetotheburnerwheneverthesafetyshut-off

valve(s)isopen.Thisislowretotheheater.Sincethepressure

regulator maintains a constant supply pressure, the minimum

ring rate is also held constant. The MR212’s regulator is

an integral component while a seperate upstream pressure

regulator is required for the M411, M511, and M611.

As voltage is applied to the control’s solenoid, a magnetic force

is applied to the plunger. The plunger in turn pushes down on

the main diaphragm of the M411, M511, and M611 valves or

allows pressure to develop in the upper chamber of the MR212

valve. These forces on the main diaphragm are very similar to

the spring loading of a gas pressure regulator. When the force

is sufcient to overcome the counter spring, the main valve

will open and gas will ow through the main valve in addition

toowingthroughthebypass.Withsufcientvoltage,themain

valve (modulator valve for the MR212) will fully open and the

pressure regulator will limit the burner pressure to the desired

amount, thus establishing a controlled maximum high re

condition.

Wenowhavetwoextremes.Therstislowrewithnoforce

ontheplungerandowthroughthebypassonly.Thesecond

ishighrewithsufcientforceontheplungertofullyopenthe

valve (modulator valve for the MR212), with the gas pressure

regulator controlling the maximum ring pressure. Force on

the plunger between these extremes results in modulated gas

ow.Thevoltageversusoutletpressurecurve,throughoutthe

modulating range, is fairly linear.

There are also applications where it is desirable to have two

seperatehighreburnersettings.Typicalapplicationswouldbe

a two speed fan operation or LP natural gas change over. This is

accomplishedbyaddinganadjustableresistancetothecircuit,

thereby limiting voltage to the valve. Changing from one setting

to another is done by connecting a single pole single throw

switch (customer supplied) that when in the open position allows

theoutlet pressureto beadjusted upto 2”w.c.below normal

maximumhighre.Negativepressurevalvesdesignedfordual

pressure settings are designated with a “- 2” sufx (example:

MR212D-2). Field conversion kits (KT/10542) to modify single

pressure valves are also available.

The working voltage to operate the modulating controls can

be supplied by the A1014, A1024, A1044, A1494 and AD1094

Ampliers or the SC11 Signal Conditioner. (Refer to Bulletin

SEL1444_CC_EN, SEL94_CC_EN, and SC11_MS_EN.)

Valves designed for direct red applications (positive

pressure/push through) MR212D-1, MR212E-1, MR212G-1,

and MR212J-1.

The valve’s operating principles are identical to the negative

pressure MR212. The only difference is the valve has been

designed to operate on positive pressure (push through)

applications. Positive pressure valves designed for dual

pressure settings are designated with a “- 3” sufx (example:

MR212D-3).

INDIRECT FIRED

Valves designed to operate on indirect red atmospheric

burner applications M420, M520, M620.

These valves function in the same manner as the direct red M

valves. A pressure adjustment spring has been factory set to

obtainanoutletpressureslightlyaboveatmosphericpressure(0.1”

w.c.) with the bypass closed and zero voltage being applied. The

minimumowrateisnowadjustedthroughthebypass.

NOTE:Minimumoutletpressureisalwaysabove0.2”w.c.

Maximumoutletpressureis7.0”w.c.

MR410, MR510, and MR610

These valves use two springs in order to set the high and low

re settings. One spring (min.) surrounds the solenoid and is

always in contact with the diaphragm assembly. The other spring

(max.) is located above the plunger. With zero voltage applied, the

minimum and maximum spring’s down force, along with plunger

weight, pushes down on the diaphragm thereby setting a regulated

highre.Aseperatepressureregulatorisnotrequired.Asvoltage

isapplied,theplungerpullsupsufcientlyuntilallplungerweight

and maximum spring force is removed. The pressure is now

controlled with the minimum spring setting giving a regulated low

recondition.Forceontheplungerbetweentheextremesresults

inmodulatedgasow.Thevoltage versus outlet pressure curve,

throughout the modulating range, is not linear.

These valves are driven with the A1010 or A1011 Amplier or

SC11 Signal Conditioners. (Refer to Bulletin SEL2030_2131_CC_

TYPICAL GAS TRAINS

Modulator (M) or Modulator-Regulator (MR) Valve: Mount in upright position in horizontal run of pipe, downstream of other controls - a

seperate gas pressure regulator must be used with any modulator (M) valve.

Figure 6 : M Valve-Regulator upstream of modulator valve Figure 7 : MR Valve-Modulator/Regulator Valve

Figure 8 : If diaphragm type automatic gas valve is used with seperate

regulator, install MR valve downstream from diaphragm gas valve. Retain

regulator in manifold and adjust 2 or 3 turns to compensate for pressure

drop of MR valve.

TYPICAL INSTALLATIONS

Figure 9 : If full combination control is used, install MR valve downstream.

Adjust regulator in combination control 2 or 3 turns to compensate for

pressure drop at MR valve.

Figure 10 : If solenoid type automatic gas valve is used with seperate

regulator, replace regulator with the MR valve.

NOTE: MR Valve must be in upright position, in horizontal run of

pipe only with pilot gas supply upstream.
