On March 2011, the NGV electronic valve group received the TÜV certification in complianceto the Standard EN 81-2:A3, which is coming into force at the end July of 2011.
The Standard EN 81-2:A3 requires more stringent safety measures according to section9.13 “protection against the uncontrolled movement of the cabin”. This requires a doublesupport with self-control which has to prevent the uncontrolled movement of the cabin withits doors and also the floor doors open. This support should be subjected to a type test. Moreover, the protection measures are considered safety components, and therefore, they must be in compliance with chapter F9 of the Standard.
Meanwhile, GMV has developed the electronic valve group NGV A3, which with CE certificate has a double safety system self-controlled as standard in compliance with the specific sections of EN 81-2: A3.
Thanks to the electronic technology the valve group NGV A3, that can be used with biodegradable fluid, a better comfort level can be achieved as well as a higher speed up to 1m/s. Furthermore, the facility consumption can be reduced up to 20% or 40%. Besides, due to the programming console the regulation and maintenance is easier and at the same time offers more security to the worker.
