6519 NAMUR Ex i Pneumatic Solenoid Valve

Brand: Burkert Fluid Control Systems

The Type 6519 NAMUR Ex i valve is used for the pneumatic control of double or single-acting actuators with a NAMUR adapter plate flange.

The circuit function can easily be changed using an adapter plate. In the 3/2 way function, feedback of the exhaust air takes place in the spring area of the armature drive.

The diaphragm-controlled valve seats work with very low friction, ensuring reliable switching of the valve even after long shutdown periods and at ambient temperatures below 0° C (32° F).

The valves work without a continuous air consumption.
