YOYAGE SERVICE
Order & Service Process
Clear support from early selection and custom design to production follow-up, quality inspection, packing, and delivery.
01
Product Selection Support
Assist in selecting suitable valve gearboxes based on key data such as valve type, valve size, required torque, stem dimensions, and connection parameters. If some information is unavailable, communicate patiently with the customer and provide the most suitable reference solution for valve drive selection.
02
Quality Requirement Review
Communicate with the client to confirm required quality certifications, waterproof standards, coating and anti-corrosion requirements, and material specifications, and provide the most suitable product based on the actual application environment.
03
Lead Time Confirmation
Confirm detailed production schedule, and delivery timeline, including potential risks and buffer periods, to ensure accurate and reliable project planning, and strive to meet customer time requirements by delivering products to customers in a timely manner.
01
Custom Design Planning
Based on the confirmed valve gearbox requirements from the initial stage, determine whether customization is needed; if required, develop customized drawings according to client specifications, otherwise proceed with standard product drawings.
02
Technical Parameter Confirmation
Our technical team confirms all valve gear operator technical parameters based on the customer's specific requirements. We also take into account all possible special conditions and edge cases during the process to ensure accuracy and reliability.
03
Drawing Review & Approval
After completing the drawings, we will reconfirm all specific requirements with the client to ensure everything is accurate and complete, and proceed to production only after final approval.
01
Production Schedule Tracking
Full production adopts process cards combined with in-process inspection to ensure all components are processed in an orderly manner according to requirements, guaranteeing efficient transmission and coordination of valve gearbox parts.
02
Efficient & High-Quality Production
Utilize fully intelligent equipment to achieve efficient production while ensuring machining precision and reliability of components, providing strong support for product durability.

Fundamentals
What Is a Valve Gearbox? Types, Parts, and How to Specify One
The definition, torque multiplication, part-turn and multi-turn structures, worm, bevel and spur gear types, and the specifications that decide the model.
Comparison
Part-Turn vs Multi-Turn Valve Gearboxes: What's the Difference?
How the two gearbox families differ in motion, torque, travel stops, ratio and actuator compatibility, and how to choose between them.
You can check the detailed specifications and customization options on our product pages. If you are unsure which model to choose, contact us by form or email, and YOYAGE will provide selection support.
Standard customization options such as flanges, stem connections, handwheels, materials, IP ratings, and coating systems are available with regular orders. Custom gear ratios beyond the standard range are subject to minimum order quantities. For special customization, minimum order quantities are decided case by case depending on the design. For small-batch orders, packaging and transportation costs may need to be covered by the customer.
Standard orders are completed in 3–20 days, depending on the specific order quantity. Customized orders are scheduled according to the specific order details — contact YOYAGE for a quotation. In all cases, customer requirements come first: YOYAGE provides convenient, efficient service for every customer and makes every effort to complete orders on time.
Yes. YOYAGE maintains complete product documents and can provide available certificates, inspection reports, and related technical files according to customer requirements.
The standard payment term is 30% advance payment after contract confirmation, with the remaining 70% paid before shipment.
