DESCRIPTION
The CVI-m system comprises a modulating gas control with
on/off regulating and modulating function and an ignition
control with integrated power supply for the electric modulating
operator.
Valves
The Combined Valve and Ignition modulating (CVI-m) system
controls and performs all the functions required for safe
ignition, flame supervision and for safely regulating the gas
flow to the main burner.
The construction of the VK4105G valve is optimized and
dedicated to function in combination with the S4565.M ignition
control.
The power supply for the modulating current is generated by
the ignition control.
The CVI-m gas control comprises a standard body to which a
range of features can be factory included to give various
functional options. These functional options include: servo
pressure regulation, modulating control to fulfil a range of
control applications.

EN2R-9025 0502R8-NE
CONSTRUCTION AND WORKING PRINCIPLES
oprerated by the 2nd coil (M). This 2nd coil also operates the
integrated modulation function by loading an integrated
regulator diaphragm (N) with the required force through
applying the appropiate current (based on % PWM input)
which is determined in the electronic circuit that is connected
to the gas control.
When the 2nd coil is energized at heat demand, but a 0%
PWM input, the plunger is moved down and the servo valve
opens. At this moment “working gas” can flow to the supply
orifice (O). At the same moment the minimum rate gas can
flow through the servo valve (K) and the minimum rate
adjustment screw (D) directly to the outlet.
When now the PWM input (heat demand) rises, the current
rises, the load on the regulator (N) rises and the pressure of
“working gas” in the servo system is being built up. At a certain
point this pressure opens the main valve (B) and the outlet
pressure rises. Now the main valve is modulating and the
outlet pressure is controlled by the balance between
generated forceon the plunger and outlet pressure through the
regulator diaphragm. The higher the force becomes, the
higher the outlet pressure will be and vice versa.
The outlet pressure can be limited to a maximum value by
setting of the maximum servo pressure regulator (C). This
maximum regulator is parallel to the integrated modulating
regulator. This means that the lowest of both settings will
determine the actual outlet pressure.
When the 2nd coil (M) is de-energized, the servo valve closes
and the supply of minimum rate gas and “working gas” are
shutt off. The load of the regulator diaphragm is released, the
“working gas” can bleed to the outlet through the regulator
seat and the main valve closes.
The VK4105G gas control contains a first direct electric ON/
OFF safety valve (A) and a second ON/OFF and modulating
servo operated main valve (B).
The modulating valve maximum output pressure can be
limited by a maximum pressure regulator (C). The minimum
output can be adjusted by a throttle adjusment screw (D).
Description of the direct electric operator
The direct electric operator (RAC) is built up with a valve seat
that is machined in the die cast body (E), the coil plate assy
that forms the upper part of the product (F) and the plunger
assy as moving part (G).
A sleeve (H) guides the plunger assy (G) and is assembled
between body and coil plate assy. If the solenoid is energized
the plunger is pulled-in and moves upwards. So the safety
valve, which is directly attached to this plunger, is opened. The
impact of the plunger on the stop is damped by a rubber
silencer in the plunger.
Description of the servo operated modulating main valve
The main valve (B) is a spring closed and diaphragm (J)
actuated valve located in the main gas passageway between
the direct operated safety valve and the outlet of the gas
control .
The main valve is opened by the servo systems “working gas”
acting against the main valve diaphragm (J). So the position of
the main valve (B) is controlled by the “working gas” pressure
in the servo system.
The “working gas” is obtained from the main gas stream
through the servo valve (K) and a supply orifice.
The servo valve is located parallel to the main valve and is
