SPECIALS INDIVIDUAL

Combustible gases, vapors and dusts mixed with oxygen form an explosive atmosphere. To ensu- SOLUTIONS
re a high level of safety, there are corresponding protective regulations for the various types of equip-
ment to prevent explosion hazards. The solenoid used as an electrical actuator in valve technolo-
gy must therefore have a type of protection corresponding to the explosion protection standard.
Constant contact with salt water and a salty atmosphere or valves that are constantly exposed to severe Hydraulic systems are used to steer and move vehicles. The functions installed, such as lifting and swivel
weather conditions require increased corrosion protection to extend their service life. arms, supports and brakes, are also operated hydraulically. They move loads and hold them in the desired
position for long periods of time. Switching valves control directions of movement, seal lines tightly and limit
pressures and flow rates to manually set values.
