Multi-turn Actuator AVA01 ~ AVA10 suitable for Globe valves, Gate valves, sluice valves, penstock and some dampers. AVA01 ~ AVA10 combined with BA bevel gearbox max can reach 100,000Nm.

Greatork GPRS water meter, it designed on the basic of standard GB/ T778.1-2018, has stainless steel cover, high anti corrosion protection,equiped with high quality sensor with zero pressure loss, big measurement range and accurate flow rate measurement.

It's our new developed gearbox, max torque can reach 1 million newton meter, the ratio can be customed according client's requirement, this gearbox can work under -60℃ extreme low temperature enviroment, can reach IP68 water tight, very suitable for application in Russia, North America or North European.

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.

Double Display Gas root flow meter add a mechanical counter to record total flow rate, the counter lubricated for life at assembly and has long service period. All port adopt photoelectric isolation design, ensure volume correction instrument work well all weather.

Double Display gas turbine flow meter has all functions and features of standard gas turbine flow meter, it's integrated with mechanical counter which free of lubricated, the counter has 8 numbers, minimum resolution ratio is 0.02m. The circuit pulse generator directly installed on counter, it will feedback low frequency pulse signal for flow record and control.

The electromagnetic meter is designed to accurate calculate water consumption and feedback to water supply enterprise, it can help increase water recovery rate, reduce loss due to leakage. This meter use full stainless steel design, can be used in high pollution/corrosion enviorment, has features like all-pass structure structure sensor, zero pressure loss, no abrasion, high range ratio, small flow sensitivity. It can used for 10 years without replacement, are widely used in water extraction, water pipe network, household measurement charging and agricultural irrigation.
