GAS CONTROLS WITH INTEGRATED 1:1 GAS/AIR REGULATOR FOR
APPLICATION
The VK41..V(B)/VK81..V(B) 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)/VK81..V(B) 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)/VK81..V(B) series are used in a system
context in conjunction with fan control and a direct spark
ignition (DSI) control.
The VK41..V(B)/VK81..V(B) series are approved in
accordance with european standards.
DESCRIPTION
VK41..V(B)/VK81..V(B) 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)/VK81..V(B) SERIES
COMBINED VALVE AND IGNITION SYSTEM
1
VK41..V(B)/VK81..V(B) 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/VK81..V 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.
