MNC Valves Ltd.
MNC Valves LimitedΒ manufactures wafer type butterfly valves designed for compact installation, economical pipeline integration, low torque operation, and reliable shut-off across water, utility, HVAC, ETP, chemical, and general industrial applications.
Compact between-flange installation design
Suitable for water, utility, HVAC, and process service
Available in resilient seated and higher performance variants
Manual, gear, pneumatic, and electric operated options
MNC Valves LimitedΒ offers wafer type butterfly valves for applications where compactness, reduced weight, and economical installation are important. This design is widely used because the valve body fits between two pipeline flanges, reducing space requirement while still providing effective isolation and control.
Wafer type butterfly valves are especially suitable for water treatment systems, utility pipelines, HVAC service, ETP plants, and general industrial flow handling where practical installation and cost efficiency matter.
AΒ wafer type butterfly valveΒ is a butterfly valve designed to be installed between two mating flanges. The body is compact and aligned using flange bolts, making it one of the most space-efficient butterfly valve constructions.
This design is commonly selected where the buyer wants lower installation weight, simple piping arrangement, and economical shut-off performance in medium and large diameter lines.
The valve body fits between two flanges, reducing installation space and making the valve more compact than many alternative designs.
The disc rotates 90 degrees for opening and closing, providing fast operation and practical flow isolation.
Wafer construction keeps the overall body lighter, which is particularly useful in larger size utility and water lines.

It is a butterfly valve designed to fit between two flanges in a compact and economical installation format.
It is commonly used in water, HVAC, utility, ETP, and general industrial service lines.
The body construction is compact and lighter, which often reduces material and installation cost.
Wafer type fits between flanges, while lug type has threaded lugs and is better for end-of-line service.
Generally lug type is preferred where end-of-line service is required.
EPDM, NBR, PTFE, and metal seats are commonly selected depending on application.
Yes, pneumatic and electric actuated versions can be provided.
Water treatment, HVAC, textile, ETP, utility, and general industrial sectors use them widely.
CI, DI, WCB, CF8, and CF8M are commonly available depending on requirement.
Yes, with proper body, disc, and seat material selection, it can be used in selected chemical applications.
PN10, PN16, PN25, and higher designs may be available depending on construction.
Common causes include wrong seat selection, damaged disc, or improper flange installation.
It can be used for limited throttling depending on design and application conditions.
Improper flange alignment can affect disc movement, sealing, and valve life.
Yes, gear operation is commonly used for larger sizes where lever operation is not practical.
