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.

View all product categories →Inspection and testing are performed according to the product type and applicable production procedure. Request the inspection scope for the selected model.
Torque, pressure, temperature, cycle-life, and protection ratings should be taken from the applicable model datasheet or test report, not from a category-wide claim.
Mounting interfaces and standards such as ISO 5211, NAMUR, VDI/VDE 3845, or other requirements are confirmed for each selected product and configuration.
Body, shaft, gear, seal, coating, and fastener materials vary by series. Confirm the bill of materials and environmental suitability before ordering.
CE, ATEX, IECEx, SIL, IP, and other documentation applies only where stated for the exact model. Certificate scope and revision should be verified during selection.
Warranty period, exclusions, spare-parts support, and technical documentation are confirmed in the quotation, order documents, or product-specific warranty terms.
Gear, shaft, housing, bearing, seal, coating, and self-locking designs vary by gearbox series. Confirm the material specification, reduction ratio, output torque, enclosure requirement, and mounting interface for the selected model.
Heat treatment may be used for selected gear components to improve hardness and wear resistance. Confirm the material and treatment for the required model.
Critical shaft and position-indicator components are machined and inspected to support dimensional consistency and reliable operation.
The self-locking design and internal component configuration depend on the gearbox series. Verify back-driving requirements and operating conditions during selection.
Available nameplate, finish, handwheel, bore, adapter, and material options depend on the gearbox series and order quantity. Confirm all requested options on the approved drawing and quotation.
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.
Remote or Extension Operation: For underground, elevated, or difficult-to-access valves.
Known Valve Torque: Provide the maximum valve operating torque and the required safety factor.
Unknown Valve Torque: Provide the valve type, size, pressure class, seat or seal material, stem dimensions, and operating conditions for engineering review.
Verification: The required valve torque, including the selected safety factor, must not exceed the gearbox rated output torque.
Drawing Review: Submit the valve top-flange and stem drawing for dimensional verification.
Connection Type: Select a square bore, keyed bore, or approved adapter to match the valve stem.
Approval: Production begins after the connection dimensions and approved drawing are confirmed.
Customization: Available options depend on the selected gearbox series and order requirements.
Nameplate or logo customization.
Coating and color options.
Grease fitting or lubrication option, where available.
Handwheel type and size selected according to the available operating space.
