Explosion-Proof Actuators
Electrical sparks are the primary cause of explosions, and the creation of these sparks is avoided by using non-ferrous materials for equipment construction. Non-sparking tools, such as hammers and shovels are typically constructed from such non-metallic materials in order to avoid the risk of ignition during use. However, this does not eliminate the possibility of an explosion from other sources, such as oxidation or static electricity triggered by equipment operation. This is where explosion proof equipment comes in – it is designed and built to operate in hazardous (classified) locations without the threat of an explosion due to any kind of ignition source.

Electric actuators, also referred to as electro-mechanical actuators or E-M actuators are a perfect solution for operating and regulating industrial valves and dampers. They offer command and control over a damper’s position, either opening or closing it or regulating the flow more intensively and precisely.

There are different types of electric actuators to meet your specific application, such as rotary and linear versions. Rotary electric actuators move the multileaf damper blades into the OPEN or CLOSED position via control input signals. These actuators have one tube connection for compressed air, and the other remains open for any attachments.

Linear electric actuators offer movement in a straight line. These devices operate with the power supply and can be used for various applications, including quarter turn butterfly valves or dampers. The linear actuators can be used in potentially explosive atmospheres and are ATEX certified. They have a robust design and are easily installed thanks to the standard ISO 5211 mounting.
