CERTIFICATIONS : DIN DVGW VP305-1Safety type : excess flow device - thermal - security hand wheelStandard of reference : DIN DVGW GermanyPower supply system : Natural gas - lpgSystem type : DomesticMax working temperature : 60°CMax working pressure : 5 bar

• To close the valve it is necessary to turn it clockwise.• To open the valve it is necessary to push down and turn the handwheel in a counter-clockwise direction.• This safety device allows to block the valve in a closed position in order to avoid accidental openings (useful with children).Push and turn safety
• To reset the device: close the valve, change the hose and re-open it. This valve does not have to be substituted after thesafety goes on. • The connection with househo d appliances can be done with hoses with maximum length of 2000 mm. • This device can be used with appliances utilizing gas combustibles fed by networks with a pressure ranging from 8 mbar to 37 mbar .• It is an automatic shut off device of the gas  flow that goes on when the flow in the pipe installed after the valve exceeds the capacity of 1.000 liters/h (1m3/h); this happens for instance when the pipe is broken or disconnected from the appliance.  Excess flow safety
• once the safety feature on this valve goes on, the valve needs to be substituted.• This valve can be installed on already existing appliances and does not required any up-keeping.• The thermal safety will withstand an exposure of thirty minutes to a temperature.of 650°C.• It does not avoid fires but avoids explosions caused very often by such events.• It is self sufficient and does not need any external sources of power to function.• The thermal safety blocks in real time the gas flow and avoids explosions in case of fire. Thermal safety device Patented triple security valve
