Combination Gas Valves

VGE...

(Smart)

The combination gas valves type VGE have been developed for use in gas-fired

heating boilers, direct-fired air heaters and back boilers with automatic ignition

systems. They are suited for use with atmospheric burners or premix burners

using an electronic cam.

The VGE and this Data Sheet are intended for use by OEMs which integrate the

combination gas valves in their products.

Use

∂ Valves of compact design, suitable for installation in small, modern gas-fired boilers

and gas appliances

∂ Specially designed for gas appliances with DBI system to ignite the main burner

∂ Multiple actuating device conforming to EN 126 with linear actuator for modulating

operation

∂ 2 independent shutoff valves

∂ 1st solenoid shutoff valve of conventional design

∂ Combination of linear actuator control section and 2nd shutoff valve

∂ Choice of valve versions and control characteristics depending on application

∂ Output limitation or change of type of gas via control electronics

∂ Pressure test points for inlet and outlet pressure accessible from top of valve

∂ No mechanical settings required

∂ Fine-mesh filter integrated on the gas inlet side

Warning notes To avoid injury to persons, damage to property or the environment, the following warning notes must be observed! Do not open, interfere with or modify the valve! ∂ ∂ ∂ ∂ ∂ All activities (mounting, installation and service work, etc.) must be performed by qualified staff Before making any wiring changes in the connection area, completely isolate the plant from mains supply (all-polar disconnection). Ensure that the plant cannot be inadvertently switched on again and that it is indeed dead.

Standards and certificates Applied directives: ∂ Low-voltage directive ∂ Gas Appliances Regulation ∂ Electromagnetic compatibility EMC (immunity) *) 2014/35/EC (EU) 216/426 2014/30/EU *) The compliance with EMC emission requirements must be checked after the combination gas valve is installed in the equipment ¹) In conjunction with LMS15 When using BMUs other than the LMS15, the system integrator assumes responsibility for the plant and must provide proof that the relevant directives are complied with.

Life cycle Combination gas valves has a designed lifetime* of 500,000 burner startup cycles which, under normal operating conditions in heating mode, correspond to approx. 10 years of usage (starting from the production date given on the type field). This lifetime is based on the endurance tests specified in standard EN161 and the table containing the relevant test documentation as published by the European Association of Component Manufacturers (Afecor) (www.afecor.org).
