VK41..V(B)(E)/VK81 .V . (B)(E) SERIES
GAS CONTROLS WITH INTEGRATED 1:1 GAS/AIR REGULATOR FOR
COMBINED VALVE AND IGNITION SYSTEM
INSTRUCTION SHEET

APPLICATION

The VK41..V(B)(E)/VK81..V(B)(E) series gas controls with
1:1 gas/air regulator have been developed for application in
domestic appliances with premix burners and automatic
ignition.
For this system, the VK41..V series gas controls have been
designed to have the S4565 series ignition control attached
directly onto the valve.
The combined system then provides programmed safe light
up, flame supervision and regulation of gas flow to the main
burner of the appliance.
The VK41..V(B)(E)/VK81..V(B)(E) series can as well be
used as stand alone in direct burner applications. The plug
(order number 45.900.441-) with integrated rectifier circuit
then has to be used.
The VK41..V(B)(E)/VK81..V(B)(E) series are used in a
system context in conjunction with fan control and a direct
spark ignition (DSI) control.
The VK41..V(B)(E)/VK81..V(B)(E) series are approved in
accordance with european standards.

DESCRIPTION

VK41..V(B)(E)/VK81..V(B)(E) gas controls perform all the
functions required to safely regulate gas flow to the main
burner of domestic central heating equipment, warm air
furnaces, back boilers and water heaters.
VK41..V(B)(E)/VK81..V(B)(E) gas controls hold a first
electric on/off direct operator for opening the safety valve of
class B according to EN161 and a second electric on/off
servo operator of class B or C to EN 161.
The pressure regulator is in accordance with class B
requirement of EN 88.
VK41..V(E)/VK81..V(E) gas controls can handle the three
gas families, manufactured gas, natural gas and LP gas.
VK41..VB/VK81..VB gas controls can handle second family
gas only.
