Main PCB board is key part of electric actuator, Greatork has a strong techanical team, we develop the program, designa and produce the electroni parts by ourself. The main PCB board is common for all type Greatork actuators, one main PCB board is suitable for all model actuators. When need modulating or fieldbus function, client need to add separate card on main PCB board.

Actuator motor is power source of electric actuator, we have a 50,000 square meter factory, nearly all parts are processed by ourself, including motor, we custmize motor according different countries and voltage, like 110V, 220V, 230V, 380V, 415V, 440V, 520V, 690V, 50Hz or 60Hz optional, all motor will installed on Greatork actuator under several strict quality control inspection and performance tests.

he linear bracket is spare parts for linear actuator, the linear bracket mainly combined with multi turn actuator to operate control valve or open close type linear valve. The thrust of linear actuator is from 8.1KN to 32KN, for higher thrust, welcome Greatork for more info.

The gearbox lever is mainly used for damper, it's the connection part between worm gearbox and damper, there is pedestal to fix the lever bracket to earth or other hard surface, the length and size of the lever can be customized according client's specific requirement, need more information, welcome contact us.

Greatork produce various gearbox, including bevel gearbox, worm gearbox, supr gearbox, extreme low temperature gearbox and IP68 water tight gearobx, we have strong design team and large production facility, can help client customize various gearbox according specific requirement, generally the delivery time of gearbox is 3-4 weeks, need more information, welcome contact us for detail.

The actuator linkage use to connect actuator with control valve, the ball bearing structure has advantage of flexiable, accurate, big twist angle. The linkage is very easy to install, adjust and maintain, suitable for nearly all type actuators, not only Greatork actuator, but also bernard, auma, rotork, limitorque, sipos and so on, it's widely used in power plant, oil&gas, mining and water treatment.
