6518/6519 Ex m Pneumatic Solenoid Valve
Brand: Burkert Fluid Control Systems
The approval Ex m is achieved by the mounting of an approved push-over coil. The cable connection and the cable are non-detachable and sealed together with the valve.
The valves can be used individually or in blocks. The maximum fluid temperature may never exceed the permissible temperature class T4 135° C (275° F), T5 100° C (212° F), T6 85° C (185° F) minus 5K.
