Usage
MODACT® MOKP Ex electric actuators are designed for control and working applications in hazardous explosive environment in accordance with EN 50014 and EN 50018, zone 1 (former SNV2) and zone 2 (former SNV1) in accordance with EN 60079-10.
The actuators are used for control of fittings by reverse rotation movement in remote control and automatic control circuits. They can be used for other appropriate units as well. Special applications should be discussed with the manufacturer.
MODACT® MOKP Ex Control electric actuators have electronic position control. They are used as terminal elements of physical value control circuits. The actuators are mounted on control units. Connection values comply with ISO 5211 or DIN 3337 specifications. The actuators can also be used for areas with flammable dust according to EN 50281-1-3.
