6519 NAMUR Ex m Pneumatic Solenoid Valve
Brand: Burkert Fluid Control SystemsType 6519 NAMUR Ex m NAMUR valve for process plants switches reliably, even when fully restricted. The valve made out of premium polyamide can be operated either as a 5/2 or a 3/2 way version through different mounting plates.
The solenoid valve Type 6014 with a coil approved for use in hazardous areas is connected as a pilot. The NAMUR flange interface allows easy assembly on different pneumatic actuators on the spot.
The valve bodies are identical with the Type 6519 NAMUR standard version.
The difference between the valves is in the coils, which are laid out and approved in different ways. By changing the coil on the valve body, it is possible to easily convert from Non-Ex operation to Ex operation (or vice versa).
Coil versions with moulded cable are designed to be push-over and can be locked in 4 x 90° displaced positions and be positioned any where in-between.
