No two corrosive-service plants are identical — the media, temperature, line size, connection standard and control philosophy all differ. Forcing a standard catalogue valve to fit those conditions is how lines leak and projects run late. Huiya manufactures custom plastic valves and piping to your exact specification, direct from our factory, in UPVC, CPVC, PPH and PVDF. Whether you need a non-standard size, a specific actuator, a particular seal compound, a different flange standard or your own branding, we build it to order — and our engineers review every spec before quoting, so you don’t discover an incompatibility after installation.
What We Can Customise
- Material — UPVC, CPVC, PPH or PVDF, matched to your media and temperature (not sure which? use our Material Selection Service)
- Valve type & configuration — true union or flanged ball valves, butterfly valves; pneumatic (double-acting / spring-return) or manual
- Dimensions & standards — ANSI, DIN or JIS
- Seals — FKM, EPDM or PTFE matched to your chemistry
- Actuation & accessories — Single/Double Acting Actuator, Solenoid Valve, Limit Switch Box, Positioner
- Connections — socket fusion, butt fusion, threaded or flanged
- Packaging & branding — neutral or your own brand (see our OEM service)
How It Works
- Send your requirement — a drawing, a spec sheet, or simply your media, concentration, temperature, pressure and sizes
- Engineering review — we confirm material and feasibility, and flag anything that won’t work before you commit
- Quotation — factory-direct pricing and a confirmed lead time, We accept sample orders and custom molding.
- Production & inspection — built to spec and checked before despatch
- Delivery — worldwide; see our Shipping page for terms and timelines
Why Buy Custom Factory-Direct
Buying a custom valve through a trading company means a markup, a translation layer between you and the people who actually make the part, and slower fixes when something needs adjusting. With Huiya your specification goes straight to the factory floor — better pricing, direct engineering dialogue, and one party accountable for the result.

Frequently Asked Questions
Can you make non-standard sizes?
Yes, absolutely. Equipped with our own in-house mold tooling capabilities, we specialize in manufacturing non-standard sizes and custom fluid control components tailored to your specific project requirements.
Do you accept customer drawings?
Yes, we do. We highly welcome customer drawings for accurate evaluation. You can send us your design files in PDF format for a quick quote. If further technical assessment is needed, our engineers also accept standard CAD formats like DWG or STEP.
Can I get a sample before a bulk order?
Certainly. We understand the importance of quality verification. We are happy to provide free samples for standard products (you only need to cover the international shipping cost). For custom-molded items, sample policies can be discussed with our sales team.
What is the minimum order for a custom item?
To support our partners in developing new markets, we offer a very flexible MOQ policy. For most custom-engineered valves, our Minimum Order Quantity (MOQ) starts as low as 10 units. Please contact us with your specifications for a precise evaluation.
