Export desk
RFQ
A useful RFQ accelerates accurate quotation. Provide contact and company details, then specify valve type (butterfly, ball, gate, plug or other), required break and run torque, gear operator type (quarter-turn worm, bevel, multi-turn or declutchable), quantity, housing material preference, IP rating and target delivery window. For OEM programs, note branding, stem interface drawings and certification requirements. Export projects should include destination country, incoterms preference and any mandatory third-party inspection. The more complete your parameters, the faster we return a model recommendation with pricing, lead time and technical submittal outline — without repeated back-and-forth on basics our engineers need to size correctly.
Submit to sales@valvewormgear.com with the parameters below, or use this checklist when calling our engineering desk.
Include valve type, torque range, quantity and destination country for the fastest accurate quotation.
Every RFQ enters our engineering queue with a unique reference and assigned application engineer. We verify completeness, cross-reference catalog models with safety factors on break torque, then prepare a written quotation with model designation, pricing bands, lead time, Incoterms and documentation scope.
OEM Programs
Valve manufacturers partner with us for OEM manufacturing built to their specifications — CAD stem interfaces, witnessed torque tests, private-label nameplates and ISO 9001 traceability throughout series production.
Series production under your brand with controlled BOM and first-article approval.
Ratio and housing sizing with lab verification and safety factor documentation.
STEP, SolidWorks and installation drawings for valve top-work integration.
Custom nameplates, manuals and packaging for regional OEM programs.
Engineering
Correct gearbox selection prevents field failures that no warranty terms can fully recover. Our application engineers support torque selection using break-to-open and running torque with appropriate safety factors, ISO 5211 flange and stem compatibility checks, material and IP class selection for corrosive or submersible duty, and integration planning for electric or pneumatic actuators with manual override. We assist during design development, tender preparation, installation commissioning and post-startup optimization — with documented recommendations suitable for EPC technical records. Send valve datasheets, stem dimensions, operating conditions and any site constraints; we respond with catalog model, adapter requirements and reference to installation and maintenance resources on our support hub.
We map valve duty — media, temperature, cycle and manual vs. automated operation — to worm ratio, housing strength and sealing strategy with written summaries for your approval records.
ISO 5211 flange tables, stem engagement guidance, safety factors on break vs. run torque and adapter part numbers before you commit.
Declutchable selection, actuator adapter dimensions, commissioning checklists and clearance envelopes for handwheel access.
International
Our export desk supports commercial invoices, packing lists, certificates of origin, EN 10204 3.1 material reports, witness inspection and freight coordination for sea, air and multimodal routes.
Supplied to utilities, EPC contractors and OEM valve manufacturers across 80+ countries — with packing and document sets structured to reduce customs and site receipt delays.
Indexed submittals, version-controlled datasheets, torque test certificates and CE / API 6D marks per destination requirements — reviewed before departure.
Repeat-order forecasting, spare parts programs and drawing revision notification for global subsidiaries and regional distributors.

FAQ
We acknowledge RFQ receipt promptly and target a substantive engineering response within 24–48 business hours when valve type, torque requirements, quantity and destination country are provided. Incomplete submissions may receive a clarification request first to avoid incorrect sizing. Urgent field replacements with serial numbers can be expedited. Complex OEM or EPC packages with custom interfaces may require additional days for technical review and internal capacity confirmation — we communicate realistic timelines in the acknowledgment message so your procurement schedule stays predictable.
Yes. OEM and ODM programs include custom stem interfaces, torque design with witnessed testing, private-label nameplates, packaging, multilingual documentation and drawing revision control under NDA. We support first-article approval before series release and maintain ISO 9001 traceability throughout production. Contact our OEM desk with annual volume forecasts, target certifications and sample requirements for a structured onboarding proposal — including MOQ, lead time and engineering milestone plan.
CAD models (STEP, IGES, SolidWorks), dimensioned installation drawings, datasheets and operation manuals are standard deliverables. Pre-order engineering release typically occurs within 24–48 hours after model confirmation for catalog units. EPC submittals can be indexed to your document numbering system. Torque test certificates, material reports and quality system certificates are included per quotation scope. All documentation is version-controlled — critical for multi-phase projects where drawing revisions must be tracked across shipments.
Our export desk prepares commercial invoices, packing lists, certificates of origin, shipping marks and compliance packages aligned to destination requirements. We coordinate with your freight forwarder on incoterms, crate specifications and consolidation. Third-party witness inspection can be scheduled at production milestones. HS codes and invoice descriptions are verified before departure to reduce customs delays. Repeat international partners benefit from streamlined document templates and call-off release procedures.
Application engineers review valve datasheets, stem and flange dimensions, operating torque, environment and duty cycle to recommend catalog models or custom options. We validate ISO 5211 compatibility, apply safety factors on break torque and identify adapter kits when required. Support extends to automation integration, declutchable selection and post-installation troubleshooting. Submit parameters via RFQ, email or technical support channel — written recommendations are provided for your project records and internal approval workflows.
Contact our engineering team to start an RFQ, onboard an OEM program, resolve a technical sizing question or coordinate an international shipment. Whether you represent a utility, valve manufacturer, distributor or EPC contractor, we provide documented engineering support from first inquiry through installation and long-term maintenance — so your gear operators are specified correctly, quoted transparently and delivered with the records your QA process requires.
