Custom Gearbox Design
Worm and bevel gearbox design developed from operating requirements and constraints.
Engineering · Custom Design
Custom design and engineering develops non-standard valve gear operators when catalog units cannot meet the requirement — unusual stems, combined bevel-worm packages, extreme torque, tight envelopes, or special materials. We provide engineering development from requirement analysis through CAD design, prototyping, and production coordination for valve brands, EPC teams, and OEM/ODM customers.
Overview
Custom design and engineering is the development capability behind non-standard valve gear operators. Where selection tools route standard cases to catalog units, custom engineering owns the exceptions: bespoke stems, combined reductions, high-temperature media, and tight installation envelopes that a standard product cannot satisfy.
Custom engineering is required when the valve or installation breaks standard assumptions — non-standard stem geometry, very high torque or ratio, right-angle access, special materials for aggressive media, or strict envelope and weight limits. Engineering development confirms feasibility, models the design, and validates it before production.
Capabilities
Worm and bevel gearbox design developed from operating requirements and constraints.
Output torque and reduction ratio engineered to the specific valve duty.
Non-standard ISO 5211 flanges, adapter plates, and drive bushings designed to the valve.
Material grade, coating, and IP sealing engineered for the target environment.
2D drawings and 3D models supporting coordination and approval.
Functional prototypes built and tested before production release.
Workflow
Custom engineering runs as a staged process so feasibility and performance are confirmed before production tooling is committed.
General workflow. Deliverables and timeline are confirmed per project.
Detailed specifications — output torque, gear ratio, ISO 5211 flange class, drive bush bore, weight, and material grades — are confirmed per project and configuration. Detailed specifications available on request — request a datasheet.

Share the valve, duty, and constraints that standard products cannot meet — our engineers assess feasibility, develop the design in CAD, prototype where needed, and coordinate production. Custom torque, ratio, mounting, and material configurations are released through drawing approval before manufacture.
Common Questions
Custom design and engineering develops non-standard valve gear operators when catalog units cannot meet the requirement — bespoke stems, combined bevel-worm packages, extreme torque or ratio, tight envelopes, or special materials. It spans requirement analysis, CAD design, technical review, prototyping, and production coordination.
A custom unit is needed when the valve or installation breaks standard assumptions: non-standard stem geometry, very high torque or reduction ratio, right-angle access in confined spaces, aggressive media requiring special materials, or strict envelope and weight limits. Custom engineering confirms feasibility and validates the design before production.
Yes. Non-standard ISO 5211 flanges, adapter plates, custom drive bushings, and special stem drives are engineered to the specific valve, with CAD drawings of the interface and load review before manufacture. Custom interfaces are common where valve and operator patterns differ or where space is constrained.
Yes. Functional prototypes are built and tested during custom development so torque, ratio, fit, and durability can be validated before production tooling is committed. Test results and refinements are documented and fed into the released production design.
Yes. Custom engineering supports OEM (build to your design) and ODM (co-developed design) programs, with private-label documentation and CAD approval before production. Detailed specifications are confirmed per developed design — request a datasheet for a specific program.
