When global buyers evaluate a new valve supplier, three questions almost always come to mind:
“Are they a genuine factory, or just a trading company?”
“Can they deliver my order safely and on time, across borders?”
“If something goes wrong, who will take responsibility and help me?”
These are not unreasonable concerns. In an industry where product quality, logistics reliability, and after-sales support are equally critical, choosing the wrong partner can mean project delays, budget overruns, and endless headaches.
At Tianjin Worlds Valve Co., Ltd. , we have spent over 19 years answering these questions with actions, not promises. Our core competence lies in butterfly valves–we manufacture them, export them globally, and stand behind them long after they leave our factory. Here is how we deliver excellence across all three pillars.
We are not a trading company. We are a direct manufacturer with our own production facility located in Tianjin, China. Our ISO 9001 quality management system, audited and certified by LRQA, governs every stage of our operation–from raw material incoming inspection to final pressure testing and packaging.
With an annual production capacity exceeding 8,000 tonnes and a dedicated team of 51–100 skilled employees, we have the scale to handle projects of any size, from sample orders to full container shipments.
As a specialist, we offer a comprehensive range of butterfly valve designs to suit virtually every application:
Type | Key Feature |
Wafer Type | Compact, bi-directional, ideal for space-constrained installations |
Lug Type | End-of-line service capable, easy maintenance |
Double Flanged | Robust, suitable for heavy-duty and large-diameter systems |
U-Type | Specialised design for complex flow conditions |
PTFE/PFA Lined | Exceptional chemical resistance for corrosive and high-purity media |
Eccentric / High Performance | Metal-to-metal sealing, handles high temperature and pressure |
Split Stem | Two-piece stem design for enhanced durability under frequent operation |
Size Range: DN50–DN3000 (2″–120″)
Pressure Ratings: PN6–PN25·Class 125 / 150·JIS 5K / 10K
We can manufacture to any flange standard–ANSI, DIN, JIS, BS, or custom–ensuring seamless integration into your existing pipeline systems.
We understand that no two applications are identical. That is why we offer an extensive selection of materials, giving you the freedom to specify exactly what your media, temperature, and pressure conditions require.

Coating: All our valves can be finished with epoxy resin coating in any RAL colour, with a standard thickness of 250μm, providing excellent corrosion protection.
Being an OEM/ODM manufacturer is not just a label for us–it is how we operate every day. We do not push you into standard catalogue items; instead, we build butterfly valves exactly to your engineering drawings, performance criteria, and brand identity.
Our flexible production lines allow us to accommodate:
Customised dimensions and pressure ratings–beyond standard DN and PN ranges
Special flange drilling–ANSI, DIN, JIS, BS, or any customer-specific pattern
Proprietary coating specifications–beyond standard RAL colours and thicknesses
Customised actuator mounting interfaces–beyond ISO 5211 if required
Branded packaging and labelling–with your logo, part numbers, and barcodes
When you work with us, your design becomes our production standard. Our engineering team collaborates closely with you throughout the process–from drawing review and material selection to sampling, mass production, and final inspection–ensuring every valve leaves our factory exactly as you envisioned.
Our products are manufactured and tested to meet the highest international standards. We hold:
ISO 9001–Quality management (LRQA audited)
CE–EU safety conformity
UKCA–UK conformity assessment
WRAS–UK drinking water safety (butterfly valves)
ACS–French health safety certification
DNV / ABS–Marine approvals (available upon request)
SGS / BV– 15+ years as an audited supplier
Testing Standards: EN 12266-1 · ISO 5208 · API 598
Every valve is fully tested before dispatch–and we provide complete test reports with every order.
Since our inception in 2007, we have exported butterfly valves to more than 50 countries across Europe, the Middle East, Southeast Asia, Africa, and the Americas. This extensive export experience means we understand the specific requirements of different markets – from pressure rating preferences to documentation standards and cultural expectations around communication.
We have been audited by SGS and Bureau Veritas for over 15 years. These rigorous third-party audits verify our factory capabilities, quality systems, and trade compliance. For our customers, this long-standing relationship with world-class inspection bodies serves as independent validation of our reliability.
We know that smooth customs clearance is essential to keeping your project on schedule. That is why we provide a complete documentation package with every shipment, including but not limited to:
Commercial Invoice and Packing List
Bill of Lading
Certificate of Origin (CO)
Material Test Reports / Mill Test Certificates
Pressure Test Reports
Inspection Reports (if third‑party inspection is required)
Product Photographs and Packaging Records
Our team is familiar with the specific document requirements for various destination countries and can adapt accordingly.
We understand that butterfly valves–especially large-diameter ones–require careful handling. Our packaging solutions are designed to protect your products during ocean freight, whether in wooden crates, steel frames, or customised packaging as per your instructions. We work with major shipping lines and freight forwarders to secure competitive freight rates and reliable sailing schedules.
With over 8,000 tonnes of annual capacity, we are well-equipped to handle bulk orders without compromising delivery timelines. Our production planning system ensures that we maintain steady workflow, even during peak seasons. For urgent projects, we can often expedite production to meet tighter deadlines.
Every order from Tianjin Worlds Valve comes with a complete set of quality documents, including material certificates (factory test reports) and pressure test reports. This means you have full traceability from raw material to finished product–an essential requirement for many quality-sensitive industries such as water supply, chemical processing, and marine engineering.
Our engineering team is available to assist with:
Product selection–We help you choose the right butterfly valve type, material combination, and actuation method for your specific application.
Installation guidance–We provide clear instructions to ensure proper installation, which is critical to valve performance and service life.
Troubleshooting–Should any issue arise, our team can diagnose problems remotely, via video call, or through detailed written guidance.
We maintain a ready inventory of commonly requested spare parts–including seats, discs, stems, seals, and actuator components–to support quick replacement and minimise your downtime. For custom components, we can manufacture them to order with the same quality standards as the original equipment.
We stand behind the quality of our products. Warranty terms are discussed and agreed upon based on the specific project requirements. Our goal is not just to sell valves, but to build long-term relationships–and that means being responsive and fair when issues arise.
We know that communication can be a concern when sourcing from overseas. That is why we have built a sales and technical support team that communicates effectively in English, with prompt response times. You will never be left wondering about the status of your order or the answer to a technical question.
At Tianjin Worlds Valve Co., Ltd., we do not just sell butterfly valves–we deliver a complete manufacturing, export, and after-sales solution. Our 19+ years of focused experience means we know what works, what lasts, and what adds real value to your projects.
While butterfly valves remain our core passion and specialty, we also manufacture gate valves, check valves, strainers, and other complementary products–giving you the convenience of a single, reliable source for your valve procurement needs.
Whether you need a standard wafer butterfly valve for a municipal water project, a custom-engineered eccentric design for a demanding offshore application, or a full package of various valve types, we have the knowledge, capacity, and commitment to deliver.
