Certification is mandatory for the use of hydraulic controls in explosion hazardous areas, such as oil and gas production, chemical and steel industries. For this purpose HAWE Hydraulik now offers its directional control valves with new, user-friendly EX solenoids. Instead of a cable with a specified length, the solenoids have a terminal box that offers the machine manufacturer maximum flexibility when selecting the cable type and length.
To meet local EX requirements, HAWE offers a variety of internationally recognized certifications such as ATEX, IECEx, and NEC. Individual countries require special cables with different lengths. These requirements can be met more easily with the new EX 23 twin solenoid and EX 22 single solenoid with terminal boxes. This allows the customer to easily use the right cable in the right length for a special application and field of use.
The HAWE product range includes various directional spools and directional seated valves with the new solenoid. In oil and gas production, for example, the proportional directional spool valve type PSL from HAWE Hydraulik has proven itself worldwide. It is preferably used for the so-called "Iron Rughneck" both on-shore and off-shore. The directional spool valve type PSL is available in 4 sizes with a volume flow of up to 1000 l/min. Different directional seated valves with the new EX solenoids allow the construction of a very energy-efficient control solution.
