Mayur (Valves) System Private Limited is a leading manufacturer of PTFE lined diaphragm valves, supplying corrosion-resistant flow control solutions to chemical processing plants across the United Kingdom.
If you handle hydrochloric acid, sulphuric acid, chlor-alkali media or high-purity process fluids, you already know what a wrong valve costs you. A leaking seat means downtime. A corroded body means an unplanned shutdown and a very awkward conversation with your plant manager. That is exactly why UK process engineers look for a PTFE diaphragm valve supplier who builds to British and European standards from day one, not as an afterthought.
Why UK Chemical Plants Prefer Lined Diaphragm Valves
The chemical industry in the UK runs on aggressive media and tight compliance. A PTFE lined diaphragm valve solves three problems at once:
- No metal-to-media contact. The lining isolates the body completely, so the valve resists acids, alkalis and solvents that would eat through standard metal valves.
- Cavity-free weir design. There are no dead pockets where product can sit and contaminate the next batch. This matters in pharma, fine chemicals and food-grade lines.
- Bubble-tight shut-off. Our valves are tested to Class VI leakage rate, which is what you want when the media is corrosive or expensive.
For engineers sourcing a corrosion resistant diaphragm valve for chlor-alkali, mineral acid or effluent duty, this combination is hard to beat.
Built to the Standards UK Buyers Actually Specify
This is where Mayur (Valves) System Private Limited stands apart from generic exporters. Our weir type diaphragm valve range is designed and tested against the specifications your procurement team already works with:
Parameter | Specification |
Design Standard | BS EN 13397:2002 (formerly BS 5156) |
Face to Face | EN 558 Series 7 |
Testing Standard | BS EN 12266-1 & 2 (2003) |
Flange / Drilling | ANSI B16.5, ASA #150, DIN 2632/33, BS 10 Table D, E, F |
Size Range | DN 15 to DN 250 (up to 10 inch) |
Pressure Rating | Up to PN 16 / ANSI Class 150 |
Lining Thickness | 3 to 5 mm |
Spark Test | 15 KVDC |
BS 10 Table D, E and F drilling is available on request, which removes the usual retrofit headache when you are replacing older valves in an existing UK plant.
Materials and Configurations We Supply
Our range as a PTFE lined diaphragm valve manufacturer covers most chemical duty requirements:
- Lining options: PTFE, PFA (ASTM D 3307), FEP (ASTM D 2116), PVDF (ASTM D 3222) and Polypropylene (ASTM D 4101)
- Body materials: Ductile Iron GGG40.3 / ASTM A395, Cast Steel ASTM A216 Gr. WCB, SS 304 (CF8) and SS 316 (CF8M)
- Diaphragm: PTFE backed with Neoprene rubber, with EPDM backup available
- Actuation: Manual handwheel, pneumatic actuator or electric actuator
- Large bore: DN 200 and DN 250 weir type valves for high-flow lines
Hydraulic testing is carried out at 15 Kg/cm² on the shell and 11 Kg/cm² on the seat, with pneumatic seat testing at 6 Kg/cm². Every valve leaves the works with test records.
