Reliable Valve Control: Optimize Performance with
Our Valve Gearboxes
Valve gearboxes provide manual or powered operation of valves in various industrial settings. Explore our robust and precise gearbox solutions for enhanced control and efficiency.
Comparing with others, JIMAI valve gearbox has below advantages:
1. Own Process: JIMAI independently processes the valve gearbox body, worm, gear, and input shaft to ensure adherence to high-quality standards.
2. Worm Treatment: All worm models endure nitriding treatment, which markedly enhances their hardness and wear resistance.
3. Position hole design: Unlike other valve gearboxes offered by suppliers, which feature only two position holes, the JIMAI valve gearbox is equipped with four position holes, each spaced at 90-degree intervals. This design significantly enhances connection stability.
4. Indicator type: JIMAI offers a visible degree scale indicator for options, allowing customers to plainly see the extent to which the valves are open or closed.
5. 3D file: JIMAI has the ability to provide 3D file of valve gearbox in all sizes, which can enhance the clients competition to win the project.

Selection Basis: Choose the appropriate valve gearbox type based on valve opening/closing frequency and installation location.
Common Types:
Standard Handwheel Type: For low-frequency operation.
Electrically Operated Type: For frequent operation or proportional control.
Valve Gearbox with Piping Network: For underground valves requiring long-distance control.
Customer Provides Torque: Customer provides the valve torque with a safety factor for easy model selection.
Customer Provides Information: If the customer is unsure of the torque, they can provide valve type, seal material, and size for model selection.
Emphasis: Compare valve torque with safety factor against the gearbox's output torque.
Verification Process: It's recommended to submit the valve drawing for verification.
Shaft Type: Can choose either square type or key type shaft.
Confirmation Steps: Provide drawing for a second inspection after verifying the connection size. Production begins upon drawing approval.
