Mayur (Valves) System Private Limited is a leading manufacturer and exporter of knife gate valves, industrial valves and lined valve systems, operating from Ahmedabad, India since 1978. Anyone who has specified a conventional gate valve into a sludge line has learned the lesson once. The gate jams on settled solids, the seat never closes cleanly, and a valve rated for decades is pulled within months.
Knife gate valves exist precisely because that failure is predictable. The bevelled blade shears through suspended solids as it closes rather than fighting them.
Why UK Water Projects Specify Them
Britain’s water and wastewater infrastructure is running an intensive capital replacement programme, and the duties involved are exactly where knife gate valves belong:
- Sludge and settled solids — primary and secondary treatment lines where conventional seating fails
- Screening and grit handling — abrasive media that destroys soft-seated valves
- Digester and thickener isolation — heavy, viscous flow requiring positive shut-off
- Storm and combined sewer overflow — infrequent operation with high reliability demand
- Effluent transfer — large-bore isolation where face-to-face dimension matters
The compact body also matters more than it first appears. Retrofitting into existing chambers and gallery spaces is far simpler with a knife gate valve than with a conventional gate valve of the same bore, which is a practical advantage on refurbishment schemes rather than greenfield builds.
Manual Knife Gate Valve Range
Our stainless steel and cast body knife gate valves are engineered for thick fluids, slurries and solid-laden media:
- Size range: 50 mm to 2500 mm
- Pressure rating: Class 150
- End connections: lugged and flanged
- Configuration: unidirectional and bidirectional
- Seat options: metal and resilient
- Body styles: semi lug and full lug types
Material selection covers the full spectrum a project may call for — cast ductile iron for medium-pressure utility service, carbon steel for general applications, stainless steel SS 304 (CF8) and SS 316 (CF8M) where corrosion resistance is required, and duplex and super duplex steel for aggressive chemistry or high-pressure duty. On coastal and estuarine treatment works where chloride exposure is a live concern, that duplex option is worth raising with any knife gate valve supplier UK consultants are evaluating.
Pneumatic Knife Gate Valves for Automated Plant
Modern treatment works run on remote and automated control, and manual operation is often impractical or unsafe at the point of installation. Our pneumatic knife gate valve UK installations require covers:
- Size range: 50 mm to 600 mm, with larger sizes available on request
- End connections: wafer, lugged and flanged
- Pressure rating: Class 150
- Actuation: pneumatic cylinder in double-acting mode, with optional electric or hydraulic actuation
- Temperature range: −29°C to 425°C
- Seat and configuration: metal or resilient seat, unidirectional or bidirectional
The same material range applies, from cast ductile iron through to super duplex, so a plant can standardise on one valve type across manual and automated positions without splitting the spare parts inventory.
What to Include in Your Enquiry
We quote against real requirements rather than assumptions. To respond accurately, send us:
- Line size and quantity for each position
- Media — sludge, screened effluent, grit, chemical dosing or process water
- Operating pressure and temperature
- Flow direction requirement — unidirectional or bidirectional
- Seat type — metal or resilient
- End connection and flange standard required
- Operation — handwheel, lever, chainwheel, pneumatic, electric or hydraulic
- Body material if already specified by the consultant or client
- Documentation — material test certificates, test reports or project-specific requirements
A valve schedule, datasheet or P&ID extract is enough for our engineering team to respond with full specification and lead time.

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, working under an ISO 9001:2015 certified quality system. We manufacture in-house rather than trading other people’s product, which means we take on genuine specification work — particular body grades, semi lug or full lug configurations, non-standard sizes, seat arrangements and actuator selection to your control philosophy. Our team replies to technical enquiries with drawings and datasheets rather than sales literature. As an established knife gate valve manufacturer, we already export to the United Kingdom alongside more than sixty countries worldwide.
Conclusion
Knife gate valves succeed where conventional gate valves fail because the blade is designed to cut through what would otherwise jam the seat. For UK water and wastewater projects, the specification decisions that matter are body material against the media, seat type against the duty, and flow configuration against the system design. Our range spans 50 mm to 2500 mm in Class 150, from cast ductile iron through to super duplex, with pneumatic automation available across the working sizes. MVS Valves supplies these direct from our works, with the documentation your project team will ask for.
Working on a treatment works upgrade, a pumping station refurbishment or a new build? Send us your valve schedule and our engineering team will return a full technical proposal covering materials, configuration and delivery. For wastewater knife gate valves on any UK project, we can quote against your drawings.
