Mayur (Valves) System Private Limited is a leading manufacturer of flanged knife gate valves, supplying slurry-ready shut-off solutions to water treatment, mining, pulp and paper and chemical plants across the United Kingdom.
Anyone who has tried to isolate a slurry line with a standard gate valve knows how that ends. The seat packs with solids, the disc will not seat, and you are left with a valve that half-closes. A knife gate valve cuts straight through the media instead of fighting it, which is why UK project engineers keep coming back to it for thick fluids, fibrous stock and solid-laden flow.
What Makes Our Knife Gate Valves Different
We build every valve around three things: a sharp bevelled blade, a sealing system that survives abrasion, and end connections that actually match your site drawings. As an established flanged knife gate valve supplier, we cover wafer, lugged and flanged patterns from the same production line, so a mixed order does not turn into a mixed lead time.
Our sealing system is where most of the value sits:
- TwinPack (standard) — graphite and PTFE blend packing for general industrial duty
- WhitePack (optional) — includes a PTFE scraper for sticky and abrasive media
That scraper matters more than people expect. It cleans the blade on every stroke, which is what keeps a slurry knife gate valve sealing after thousands of cycles rather than a few hundred.

Materials We Supply
As a knife gate valve manufacturer with in-house material control, we quote against your media, not against a fixed catalogue:
- Body: EN 1.4408 stainless steel or EN 5.3105 ductile iron as standard; EN 1.4470 duplex, Titanium B265, Hastelloy C276 and 254 SMO for severe service
- Gate / Blade: EN 1.4404 or EN 1.4301 stainless steel with bevelled edge; duplex EN 1.4462, titanium or polished chrome-coated options
- Seat Insert: PTFE, NBR, EPDM or polyurethane; FDA-grade PTFE and stainless metal seats available, with EC 1935/2004 compliant options for food contact
- Packing: TwinPack graphite/PTFE blend or WhitePack with pure graphite
For potable water, effluent and food-grade lines in the UK, the EC 1935/2004 compliant seat option is usually the one buyers ask about first. It is available across our stainless steel knife gate valve range.
Where UK Buyers Are Installing Them
Our valves run in water and wastewater treatment, pulp and paper, mining and mineral processing, chemical and petrochemical plants, cement and construction, steel processing, and environmental and biogas facilities. Sites in London, Manchester, Birmingham, Bristol and Glasgow fall within our regular UK export lanes, and we have been shipping to the United Kingdom for years as part of our 60-plus country export network.
What to Send Us for a Faster Quote
RFQs move quicker when the basics arrive together. Send us:
- Line size and end connection (wafer, lugged knife gate valve or flanged)
- Media type, solids content and operating temperature
- Pressure rating and required flange standard
- Operation type: handwheel, chain wheel, lever or actuated
- Quantity and required delivery window
With those five points, our engineering team can turn a technical offer around without the usual back-and-forth.

Why Choose Us
We have been manufacturing and exporting industrial valves since 1978, backed by ISO 9001:2015 certification and a track record across more than 60 countries including the United Kingdom. What our UK clients value most is that we handle the engineering conversation ourselves rather than passing it to a trading desk. Our team reviews your media, solids loading and flange standard before quoting, then builds the valve accordingly, whether that means a duplex body for chloride-rich effluent or a WhitePack scraper for abrasive tailings. Because production, material selection and testing sit under one roof, we control the schedule and keep commitments realistic. That is the difference between a flanged knife gate valve supplier who quotes and one who delivers.
Conclusion
Choosing the right knife gate valve is less about the catalogue photo and more about matching blade, seat and packing to what actually flows through your line. Our range covers DN 50 to DN 600 in Class 150, across wafer, lugged and flanged ends, with body materials from ductile iron through to Hastelloy C276 and 254 SMO for the hardest duties. Whether you are specifying a single replacement valve for a UK treatment works or building a full slurry isolation package for a new plant, we can engineer it, manufacture it and ship it with complete documentation. Send us your line details and let our team recommend the correct configuration first time.
