VK41..VK81..A/B/C/D GAS CONTROLS FOR COMBINED VALVE AND IGNITION SYSTEM INSTRUCTION SHEET SPECIFICATIONS Model VK41.0: 220 ... 240 Vrac VK41.5: 220 ... 240 Vrac without pilot burner connection VK81.0: 24 Vrac VK81.5: 24 Vrac without pilot burner connection Suffix A: fast opening with pressure regulator Suffix B: fast opening without pressure regulator Suffix C: softlite opening with pressure regulator Suffix D: softlite opening without pressure regulator Main gas connection See table 1. 3/ ” or 1/ ” straight or elbow flanges are according to the 8 2 torsion and bending stress of EN 126 group 2 Side outlet (optional) can be mounted directly to a burner manifold. Pilot gas connection (where applicable) M8 x 1 thread for 4 mm outer diameter tubing. Pressure feedback connection APPLICATION Servo pressure regulator has an M5 threaded hole for connection between pressure regulator and combustion chamber of the appliance. The VK41../VK81.. gas controls for Combined Valve and Ignition system (CVI) have specially been developed for Ambient temperature application in gas fired appliances with either intermittent pilot 5 ... 140° F (IP) or direct burner ignition (DBI). Dimensions For this system, the VK41../VK81.. series gas controls have See fig. 1. been designed to have the S4565/S4575/S4585 series ignition control attached directly onto the valve. Pressure regulation function The combined system then provides programmed safe light Class A according to EN 88 up, flame supervision and regulation of gas flow to the main Subject to change without notice. Printed in the Netherlands. Outlet pressure burner and/or pilot burner of the appliance. Outlet pressure is pressure drop across the main burner The VK41.5/VK81.5 series gas controls can also be used as orifice. stand alone in direct burner applications. A plug with an integrated rectifier circuit then has to be used Outlet pressure range (order number 45.900.441--). 0.022 ... 0.29 psi (0.6 ... 8” w.c.) 0.029 ... 0.46 psi (0.8 ... 13“ w.c.) The VK41../VK81.. gas controls can handle the three gas families, manufactured gas, natural gas and LP gas. Maximum inlet pressure 1/ psi The VK41../VK81.. gas controls are approved in accordance 2 with: Minimum regulation capacity AGA; (ANSI Z21.78--1997) 35000 BTU at Dp= 0.0072 psi (0.2” w.c.) accross main burner CGA; (CAN/CGA--6.20--M97, 1997). orifice at 0.5 psi operating pressure maximum. DESCRIPTION Minimum operating gas pressure 0.22 psi (15 mbar) The VK41../VK81.. gas controls hold a first electric on/off Maximum operating gas pressure direct operator for opening the safety valve of class B The Pmax 1/2 psi (35 mbar) indication on the housing of the according to EN 161 and a second electric on/off servo gas control is the maximum inlet pressure at which the gas operator of class C or J according to EN 161. control functions safely.
