Burkert’s compact and powerful solenoid valve types 7011 and 7012 are now available with the circuit function “normally open”, the plug form C as well as the approval DVGW EN 161 for fuel gases or as encapsulated variant for the use in potentially explosive atmospheres (ATEX, IECEx).
Compact valves thanks to optimised coil design
More and more compact and at the same time powerful valves are required in potentially explosive atmospheres or when combustible gases are used.
With the help of the AC08 coil technology of Type 7011 and Type 7012, Burkert was able to improve the performance of the valves thanks to the optimised ratio between the iron circuit and the solenoid coil winding.
For example, the 24.5 mm coil with encapsulation is one of the smallest Ex m coils on the market. This allows smaller and compact control cabinets to be realised in the potentially explosive atmosphere. With type 7011 Burkert also offers one of the smallest gas valves on the market.
Reliable, even at higher temperatures & switching pressure
All versions of type 7011 and type 7012 can be switched reliably at higher switching pressure and increased ambient temperatures of 75°C. This makes the new articles ideal for use in numerous applications, such as:
Dust explosion protection:
- Pneumatic conveyors
- Venting technology in, for example, mills, sugar refineries or coal mining
Gas explosion protection
- Mineral oil industry
- Refuelling and storage
- Gas plants
- Painting lines
- Industrial burners (e.g. ignition gas valves)
- Movable and stationary automatic heaters
