PVG-EX
The Danfoss PVG-EX program is an explosion-proof PVG designed to be used in Ex hazardous areas like mining and oil and gas industries.
The PVG-EX is developed according to and in compliance with:
EU Directive 2014/34/EU Equipment for explosive atmosphere - ATEX
•EN 60079-0:2012/A11:2013 Electrical apparatus for explosive gas atmospheres-part 0
•EN 80079-36:2016 Non-electrical equipment for explosive atmospheres – Basic method and requirements
•EN 80079-37:2016 Non-electrical equipment for explosive atmospheres – Non-electrical type of protection constructional safety “c”, control of ignition sources “b”, liquid immersion “k”
•EN 80079-38:2016 Equipment and components in explosive atmospheres in underground mines
W Warning
All brands and all types of directional control or proportional valves, which are used in many different operation conditions and applications, can fail and cause serious damage.
Analyze all aspects of the application. The machine builder/system integrator alone is responsible for making the final selection of the products and assuring that all performance, safety and warning requirements of the application are met.
The process of choosing the control system and safety levels is governed by Machinery Directive 2006-42-EC, and harmonized standard EN 13849 (Safety related requirements for control systems).
W Warning
All national safety regulations must be fulfilled in connection with installation, start-up and operation of Danfoss PVG-EX.
Furthermore, the requirements of the Declaration of Conformity and national regulations for installations in potentially explosive atmospheres applies as well. Disregarding such regulations involves a risk of serious personal injury or extensive material damage.
W Warning
Work in connection with the valve group must be performed only by professionals and qualified persons.
W Warning
PVG with non-conductive coating must have preventive protection against electrostatic charge by an earthed metal connection.
