China Actuator ML series linear electric actuators are designed to provide thrust force ranges from 2500 to 25000 kgf Standard with modulating control fits with globe valves and other linear motion devices (stroke length up to 50mm and 100mm) applied to HVAC and industrial automation, especially suitable for steam or high temperature employment such as boilers and heating system. Manual override is equipped to provide fast manual positioning of the valve and a position indicator at drive stem area allows valve position identification. The stroke is adjustable to match with valve stem travel within rated length Our explosion-proof linear electric actuators provide thrust ranges of 2500 to 25000 kgf. All models are equipped with modulating controllers and are suitable for globe valves, gate valves and linear travel devices. They can be applied for HVAC and industrial purposes, especially for steam and high temperature employments. MLS series explosion-proof electric linear actuators are structured as flame-proof and combustible dust-proof. The directive and standards marking are II2GD Ex db IIB T4 Gb Ta -30掳C to +70掳C, Ex tb IIIC T130掳C Db. They are control devices for valves and can be used in places, classified as Zone 1 or Zone 2, containing Group IIA and Group IIB gases, Zone 21 or Zone 22, containing combustible dust atmospheres or a mixture of explosive gas atmospheres and combustible dust atmospheres. Temperature group T1 to T4. Corrosion level: Epoxy powder coating. NEMA 4X corrosion protection Ingress protection: IP67 (IP68 is optional) Motor specification: Class F, with thermal protector up to 135掳C Max stroke:100 mm Running speeds: 1.5 mm/s Electrical interface:IP67, Optional:IP68 On/off type signal: Input : AC 110/220 Input Signal Feedback: Integrated fault contacts, Close the valve contact, Open the valve contact Handwheel operated manually Forced Switch/Limit Switch Space heater with thermostat to prevent overheating Provide a wide range of voltage Strong structure, accurate positioning, reliable performance Valve position detecting mechanism Through direct connection of rack on the output shaft and two sets of gears control mechanism to detect real-time valve position and fully open fully closed position independently. It will maximum improve the accuracy and security.China Actuator website:http://www.mewayvalve.com/actuator/
