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.
