Honeywell VK 4105 M 2071 U gas block

VK41..VK81..M/N GAS CONTROLS WITH ELECTRIC MODULATING PRESSURE REGULATOR FOR COMBINED VALVE AND IGNITION SYSTEM INSTRUCTION SHEET The build on Modureg V7335 is designed to work together with the W9335 modulating control, W4115 driver, a T7335 thermistor temperature sensor and an advanced range of micro computer based modulating controls. The VK41../VK81..M,N gas controls are approved in accordance with: AGA; (ANSI Z21.78--1997) CGA; (CAN/CGA--6.20--M97, 1997) The VK41../VK81..M/N gas controls can handle the three gas families, manufactured gas, natural gas and LP gas. DESCRIPTION The VK41../VK81..M/N gas control holds a first electric on/off direct operator for opening the safety valve of class B according to EN 161 and a second electric on/off servo operator of class C or J according to EN 161. SPECIFICATIONS APPLICATION Model VK41.0: 220 ... 240 Vrac VK41.5: 220 ... 240 Vrac without pilot burner connection The VK41../VK81..M/N gas controls for Combined Valve and VK81.0: 24 Vrac Ignition system (CVI) have specially been developed for VK81.5: 24 Vrac without pilot burner connection application in gas fired appliances with either intermittent pilot (IP) or direct burner ignition(DBI). Suffix M: fast opening with electric modulating pressure regulator For this system, the VK41../VK81..M/N series gas valves Suffix N: softlite opening with electric modulating pressure have been designed to have the S4565/S4575/S4585 series regulator ignition control attached directly onto the valve. Main gas connection The combined system then provides programmed safe light up, flame supervision and regulation of gas flow to the main See table 1. 3/ ” or 1/ ” straight or elbow flanges are according to the burner and/or pilot burner of the appliance. 8 2 torsion and bending stress of EN 126 group 2 The VK41../VK81..M/N gas control can also be used as stand Side outlet (optional) can be mounted directly to a burner alone in direct burner applications. manifold. A plug with an integrated rectifier circuit then has to be used (order number 45.900.441--). Pilot gas connection (where applicable) The VK41../VK81..M,N gas control with the V7335A electric M8 x 1 thread for 4 mm outer diameter tubing. modulating pressure regulator (Modureg) has the folowing Pressure feedback connection functions: M5 threaded hole for connection between the Modureg and · Servo pressure regulation the combustion chamber of the appliance. Outlet pressure is held at a constant value regardless of fluctuations of input pressure. Ambient temperature 5 ... 140° F · Modulating control Between minimum and maximum outlet pressure gas Dimensions supply to the appliance is dependent on the electrical See fig. 1. signal to the modulating coil. Pressure regulation function · Mechanical limitation of outlet pressure Class A according to EN 88 The minimum and maximum burner pressures are mechanically adjusted to guarantee good burner Outlet pressure performance in case the modulating control should Outlet pressure is pressure drop across the main burner become out of range. orifice.
