Mayur (Valves) System Private Limited is a leading manufacturer and exporter of industrial valves, PTFE lined valves and thermoplastic valves, operating from Ahmedabad, India since 1978. When a UK buyer searches for an API certified valve manufacturer, what they are usually trying to establish is simpler than the phrase suggests: will this valve meet the standard my specification calls for, and will the paperwork survive scrutiny from my client’s inspector?
Those are the right questions. Here is how to answer them properly before placing an overseas order.
What API Standards Actually Cover
The American Petroleum Institute publishes product specifications that define how a valve must be designed, manufactured and tested. Different standards govern different valve types:
- API 6D — pipeline valves, including ball, check, gate and plug designs
- API 608 — metal ball valves with flanged, threaded and welding ends
- API 609 — butterfly valves in lug and wafer configurations
- API 598 — the testing standard covering valve inspection and pressure testing
A valve built to these specifications carries defined requirements for shell thickness, seat design, stem retention, marking and test acceptance criteria. That is what a specification engineer is checking when they write “to API 6D” on a datasheet.
The Distinction Worth Understanding
There is a difference between a valve manufactured to API specifications and a facility holding an API Monogram licence, and buyers benefit from knowing which they need.
The Monogram is a voluntary licensing programme under which API authorises a manufacturer to apply the registered API mark to products, backed by an API Spec Q1 quality management system and periodic audits. Licensed facilities appear on the publicly searchable API Composite List.
If your project specification mandates monogrammed product — common on upstream oil and gas work — verify any supplier’s licence number against that list rather than accepting a claim. If your specification calls for valves designed and tested to API standards, which covers a large share of chemical, water, power and general industrial work, then design conformance and test documentation are what matter.
Any credible industrial valve exporter to UK projects should be able to explain which of these applies to your order without ambiguity. We do.
What We Manufacture and to Which Standards
Our valves are engineered in compliance with API, ASME, EN, ISO, JIS, DIN, BS, GOST and GB standards. Across the range that means:
- Ball valves — API 6D and API 608, ASME B16.34, BS EN ISO 17292 and BS EN 1983, Class 150 through Class 2500
- Butterfly valves — API 609, BS 5155 and MSS-SP-67, DN 50 to DN 1200
- Diaphragm valves — BS EN 13397:2002, 15 mm to 250 mm
- Gate, globe, plug, check, knife gate valves, strainers and sight glasses to their respective applicable standards
- PTFE, PFA, PVDF and PP lined valves and matching lined pipe fittings
Material options span carbon steel (WCB), stainless steel CF8 and CF8M, duplex and super duplex, ductile iron and special alloys. As an API 6D ball valve manufacturer, we supply fire safe construction, anti-static devices, blowout-proof stems and ISO 5211 actuator mounting across the ball valve range.
Testing and Documentation
Every valve is tested before dispatch. Depending on product type this includes hydrostatic shell and seat testing, pneumatic seat testing, spark testing on lined valves, and inspection to API 598 where applicable.
For UK buyers, the documentation package usually matters as much as the valve. We supply material test certificates, hydrostatic and pneumatic test reports, dimensional drawings and packing documentation. If your client, consultant or PMC team requires a specific certificate format or third-party inspection, tell us at enquiry stage rather than at dispatch.
Exporting to the United Kingdom
We have exported since 1978 and currently supply more than forty countries across Europe, North America, the Middle East, Southeast Asia and Russia, including the United Kingdom. Practical points that matter on UK orders:
- Flange standards — ANSI, DIN and BS 10 Table D, E or F drilling available for retrofit into existing British pipework
- Threaded ends — BSPT as well as NPT
- Documentation — supplied with the consignment, not chased afterwards
- Direct communication — your engineer speaks to ours, without a distributor in between
We Supply Across the United Kingdom
Wherever your plant or project site sits, we deliver:
1. Northwest England — Manchester and Liverpool, serving chemicals, oil and gas and manufacturing plants
- Yorkshire & Humber — Hull, Leeds and Sheffield, supplying water utilities, chemical works and steel producers
- Northeast England — Teesside and Middlesbrough, for petrochemical, LNG and fertiliser facilities
- West Midlands — Birmingham, supporting manufacturers and EPC contractors

Why Choose Us
Mayur (Valves) System Private Limited has manufactured and exported since 1978 and remains one of India’s largest diaphragm and ball valve exporters, operating an ISO 9001 certified valve manufacturer quality system to the 2015 revision. We manufacture in-house rather than trading other people’s product, which means we accept genuine specification work across materials, pressure classes, end connections and actuation. Our quality control process is systematic and fully documented, carried out by trained personnel using appropriate inspection equipment. We answer technical enquiries with drawings and datasheets, and we are direct about what we can supply, to which standard, and by when.
Conclusion
Importing valves well comes down to matching the standard your specification demands with a manufacturer who can evidence conformance and supply the documentation to prove it. API 6D, API 608, API 609 and API 598 each govern different aspects of that, and knowing which applies to your order prevents costly disputes at inspection. Our range spans ball, butterfly, diaphragm, gate, globe, plug, check, knife gate, lined and thermoplastic valves, built to API, ASME, EN, ISO, BS and DIN standards. MVS Valves supplies UK buyers direct from our Ahmedabad works.
Send us your valve schedule, datasheet or specification and our engineering team will confirm applicable standards, materials, testing and lead times for your project.
