Explosion-proof valves
Explosion-proof valves are used in environments with explosive liquids, gases, vapors and dusts. Especially in the oil and gas sector, chemical industry, but also in mines with high dust generation or gas influx, explosion protection technology is mandatory. Such explosion-hazard zones are also found in shipping and offshore industries, wood processing and grain mills.
Therefore, valves operating hydraulic systems in these hazardous areas have to be compliant and certified according to Ex-protection standards.
Wandfluh Ex d explosion-proof valves
Wandfluh Ex d explosion-proof valves are equipped with the pressure tight encapsulated Ex d solenoid. Its flameproof enclosure prevents an explosion in the interior from getting outside. In addition the Ex d solenoid also prevents an ignitable surface temperature.
