Product Description

The JMG series rotary valve gearbox utilizes a 40cr material shaft, which is known for its superior strength. Additionally, the surface has been subjected to carbonization treatment, which significantly enhances its overall strength and ensures its functionality in challenging operating conditions. JIMAI offers a broader temperature range of -45°C to 180°C for use. The gear contact ratio of the JMG series rotary valve gearbox is exceptional, and JIMAI guarantees a process difference of no more than 0.1mm.Use of our gearbox can facilitate valve control that is more precise and comfortable.

Product Features

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.

Unit featuring high efficiency reduction

90° rotation (±5°)

Self-locking device that is stable

Temp range: -45℃ to 180℃, providing a broader temperature range for use
