V7335A “2000” SERIES

ELECTRIC MODULATING PRESSURE REGULATOR (MODUREG)

APPLICATION

The V7335 ”2000” series electric modulating pressure 
regulator (Modureg), when installed on V4400/V4400, VK41../
VK81.., V(R)46../V(R)86.., V(R)49../V(R)89.. and V4085 
series gas controls, expands their application versatility and 
provides the following extra functions:

••••

Servo pressure regulation

Outlet pressure is held at a constant value regardless of 

fluctuations of input pressure.

••••

Modulating control

Between minimum and maximum outlet pressure gas 

supply to the appliance is dependent on the electrical signal 
to modulating coil.

Mechanical limitation of outlet pressure

The minimum and maximum burner pressures are 

mechanically adjusted to guarantee good burner 
performance in case the modulating control should become 
out of range.

The V7335 is designed to work together with the W9335 
modulating Modureg control, W4115 logic control, T7335A 
thermistor temperature sensor and an advanced range of 
micro computer based modulating controls.

SPECIFICATIONS

In general the specifications of the concerned gas controls are 
valid. See the corresponding instruction sheet:
MU1R-9003 for V4400/V8800 series gas controls
MU1R-9020 for V4600/V8600 series gas controls
MU1R-9043 for V(R)49../V(R)89.. series gas controls
MU1R-9082 for VR46../VR86.. series gas controls
EN1R-9162 for VK41../VK81.. series gas controls
However the following information is deviating and replaces 
therefore the relevant information of that instruction sheet.

Model

Gas controls:
Suffix M: fast opening with Modureg.
Suffix N: slow opening with Modureg.
Modulating pressure regulator: 
V7335A low voltage Modureg

Adjustment points and dimensions

See fig. 1. page 13

Regulator output pressure range

See table 1. page 2

Electrical rating

See table 2. page 2

Electrical connection

The Modureg is provided with quick connect terminals which 
are suitable for 6.3 mm (

1

/

4

”) receptacles (e.g.series “250” 

fasteners).

Pressure feedback connection

The Modureg regulator has an M5 threaded hole for 
connection between regulator and combustion chamber of 
appliance.
