Valve control that is more precise and comfortable
The JMG series rotary valve gearbox with electric actuator from Zhejiang Jimai Auto-tech Co., Ltd. is distinguished by its capacity to be assembled with the electric actuator. The valve gearbox of this type can be remotely controlled by an electric actuator by inputting a signal, thereby saving time and personnel costs.

Furthermore, the JMG series rotary valve gearbox with electric actuator is capable of accomplishing a 90-degree rotation, rendering it a versatile asset in the field of quarter-turn valves, including butterfly valves and ball valves. The ASTM5140 material shaft, which is renowned for its exceptional robustness, is employed in the JMG series rotary valve gearbox with electric actuator. In addition, the surface has been subjected to a carbonisation treatment, which considerably improves its overall strength and guarantees its functionality in rigorous operating environments. JIMAI provides a wider temperature range of -45°C to 180°C for use. The JMG series rotary valve gearbox with electric actuator boasts an exceptional gear contact ratio, and JIMAI guarantees a process difference of no more than 0.1mm.The utilisation of our gearbox can enable valve control that is more precise and comfortable.
Torque range: 260N.m to 150000Nm
Capable of guaranteeing a gear contact ratio that is greater than that of a 0.1mm disparity in the process.
Use a ASTM5140 material for the shaft, which has a significantly higher strength.
The surface has been subjected to carbonization treatment.
