6519 NAMUR Pneumatic Solenoid Valve
Brand: Burkert Fluid Control Systems
The valve bodies of Type 6519 NAMUR are identical with the Ex m variants.
The difference 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).
The coils are designed to be push-over and can be locked in 4 x 90° displaced positions and be positioned any where in-between.
