The new high-flow high-speed EExd Namur series solenoid valves from Alcon, are designed for use in hazardous area/extreme environment applications. Offering universal 5/2 or 3/2 operations in offshore, processing and chemical industries, the series is suitable for piloting single or double actuators on Namur solenoid valves. The valve offers an explosion proof, submersible, water tight and dust tight aluminium body suitable for indoor or outdoor use, along with Nitrile seals. Alcon Namur series solenoid valves are designed for use with actuators controlling butterfly and ball valve systems in hazardous areas found in offshore, paper, recycling, food processing and chemical industries. A solenoid activated spool valve system allows for rapid response times of up to 5 cycles per second, and the duty cycle of the coil has been 100% continuously rated for a multi-million-cycle life span. The new valves offer an operating pressure window of between 2.5 and 10bar and are suitable in environments where fluid/gas temperatures from -10 to +80C can be expected. Coil voltage can be 12 or 24V DC, and AC operation is possible with 24, 110, 120, 220 and 230V 50/60Hz voltages.
