6518/6519 Ex i Pneumatic Solenoid Valve
Brand: Burkert Fluid Control Systems
The intrinsically-safe Type 6518 Ex i and 6519 Ex i valves consist of an intrinsically-safe pilot control and a pneumatic amplifier.
The diaphragm-controlled valve seats work with very low friction, ensuring reliable switching of the valve, even after long shutdown periods.
