A Valve Order Is More Than a Part Number.
Send us your valve schedule, BOM or replacement photos. Before quoting, our team checks the missing details—size, pressure, materials, connection, actuation and service conditions—so the order starts with fewer assumptions.
Start With the Valve Duty, Then Confirm the Model
Our current focus covers isolation, non-return and water-control duties. Detailed model ranges will continue to be added without changing this clear product structure.
Gate Valves
Isolation for waterworks, utilities and industrial pipelines.
Butterfly Valves
Compact isolation and control with multiple actuation options.
Check Valves
Pipeline and pump protection against reverse flow.
Hydraulic Control Valves
Pressure, level and flow management for water systems.
Your RFQ, Clarified Before It Enters Production
A fast quotation is useful only when it describes the right valve. We make the unresolved points visible instead of hiding them behind a generic price.
You send what you have
A valve schedule, BOM, drawing, specification, nameplate or existing-valve photo.
We mark the gaps
Missing pressure class, material, connection, medium, temperature or actuator information is listed clearly.
Both sides confirm the basis
The proposed configuration, documents, inspection scope and commercial assumptions are aligned.
The order becomes traceable
Approved requirements remain connected to production, inspection, packing and shipment records.
Production in Nan’an. Export Coordination in Dongguan.
International purchasing crosses functions and locations. We show who is responsible instead of presenting the business as an anonymous factory.
Production Team · Nan’an, Fujian
The people supporting machining, assembly, inspection, pressure testing, packing and day-to-day production coordination.
One commercial contact, connected to the production team.
The Dongguan team coordinates English-language inquiries, technical clarification, quotation revisions, order follow-up and export communication.
Ask for the Records Your Project Actually Needs
Inspection requirements differ by order. Confirm the documentation scope before production rather than assuming every certificate or report applies to every valve.
Organized Around Systems, Not Buzzwords
The same valve type can behave differently across water, building-service and industrial duties. Application information belongs in the selection conversation.
Municipal Water
Isolation, non-return, air and pressure-control duties for distribution networks.
Wastewater
Valve selection with attention to solids, access, coating and maintenance conditions.
Fire & Building Services
Project-driven valve packages for pump rooms, HVAC and fire-water systems.
Industrial & OEM
Configuration, labels, packaging and documentation aligned with repeat purchasing.
Certificates Should Be Read With Their Scope
Management-system and production documents are presented for supplier qualification. Product- or market-specific compliance is confirmed separately for each inquiry.
ISO 9001 Quality Management
ISO 14001 Environmental Management
ISO 45001 Health & Safety
Special Equipment Production License
Send the Schedule. We Will Help Turn It Into a Quote.
If information is missing, send the documents you already have. The team will identify the next questions instead of asking you to complete a generic form from scratch.
Useful information to include
- Valve type or existing model
- DN / NPS
- PN / ASME Class
- Medium and temperature
- Body and trim materials
- End connection and standard
- Actuation
- Quantity and destination
Before You Send an Inquiry
Can HSVA review an incomplete valve schedule?
Yes. Send the available schedule, BOM, drawing or replacement-valve information. Missing technical points can be listed for confirmation before a final quotation.
Does every certificate shown apply to every product?
No. Management-system, production and product-specific certificates have different scopes. Required compliance should be confirmed against the exact model, market and project.
Can distributors request OEM labeling and packaging?
OEM requirements can be reviewed for labels, nameplates, cartons, manuals and packing marks, subject to model, quantity and compliance requirements.
What helps HSVA quote more accurately?
Valve type, size, pressure, materials, connection standard, medium, temperature, actuation, quantity and destination are the most useful starting points.
