• High flow-rate capacity Reduced power consumption Single or manifold mounting Standard, Ex mb, Ex eb mb and Ex ia versions Threaded port G ¼" and NPT ¼" The Type 6518 is a servo-assisted 3/2-way valve and the Type 6519 is a 5/2 or 5/3 way valve. Together, they form a product line. The valves can be used individually or in blocks. The valves work without a continuous air consump‑ tion and are used for the pneumatic control of double or single acting actua‑ tors. The use of high quality materials makes it possible to use these valves in the open air and under chemical atmospheres. The product line contains units with Ex-Approvals and NAMUR flange interface. Valves with circuit function C, D and H monostable are certified acc. IEC 61508 as SIL2. Product variants described in the data sheet may differ from the product presentation and description.

The units may only be used in potentially explosive atmospheres in the manner approved by the admis sion board, i.e. the permissible maximum electrical values must be observed. The valve is intended for operation on 24 V DC outputs via the intermediate switching of a corresponding intrinsically-safe operating resource (isolating module or barrier). The intrinsically-safe Type 6518 Ex i valve 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 shut down periods.
