Description
AWWA Butterfly Valves to Meet Your Application Requirements
At Cair Euromatic Automation, we design and manufacture high-performance Large AWWA Butterfly Valves in India that deliver safe, smooth, and reliable flow control for water, wastewater, and industrial applications. Our valves are engineered to perform in tough environments while ensuring long service life and minimum maintenance.
MS Fabricated 2-Way Double Flanged AWWA Butterfly Valves
We specialize in Double Flanged MS Fabricated 2-Way AWWA Butterfly Valves, built for bi-directional flow control and leak-free operation. Manufactured from high-quality mild steel, these valves offer excellent strength, durability, and corrosion resistance.
They are available in large sizes from 50” to 110”, making them ideal for heavy-duty pipeline systems. Equipped with EPDM seals and tested for PN 10/20 pressure ratings, they fully comply with AWWA C207 standards, ensuring dependable performance even under continuous operation.
These valves are widely used in:
-
Water distribution networks
-
Raw water transmission
-
Wastewater treatment plants
-
Industrial process lines
-
Irrigation and infrastructure projects
Metal-to-Metal Seated AWWA Butterfly Valves
For demanding and high-temperature applications, Cair Euromatic also offers Metal-to-Metal Seated MS Fabricated AWWA Butterfly Valves. These valves maintain tight sealing and stable performance where rubber-seated valves cannot perform effectively.

Big Diameter AWWA Butterfly Valve Features
- GGG40/50 Ductile Iron Body & Disc allows high impact and stretching resistance.
- AWWA Butterfly Valve Design.
- Resilient Seated Type.
- Disc sealing ring EPDM as default. NBR or VITON options are available.
- Block moulded solid/one-piece T-shaped disc sealing ring extends drop-tight sealing life time.
- Easy to replace disc sealing ring without dismantling the valve from the pipeline and without dismantling the disc from the valve itself just by taking out the retaining ring through its bolts. Iit is easy to replace the disc sealing ring without any additional equipment.
- SS308/316 grade stainless steel welding seat on the body is manufactured through automatic welding machines and micro finished precise milling operation. When disc is fully closed, disc sealing ring applies equal pressure on every point on the welding seat.
- Drop-tight closure.
- Double O-ring feature on both shafts ensures high sealing.
- Shafts are equipped with bronze bushings having high corrosion resistance.
- Ensures minimized pressure loss and increased energy efficiency with double shaft design.
- With the o-rings on the bearing bushings, disc pin holes are protected against corrosion. Dry shaft up to request.
- Easy to operate with self locking gearbox equipped with mechanical indicator.
- Low torque requirements during operation.
- Easy to install on the line, light weight and occupies less space.
- Full coating on the body and disc internally & externally with an average of 250 microns. Higher coating thicknesses are available when required.
- WRAS approved coating available upon request which meets hygienic requirements for potable water applications.
- Maintenance free design for the valve and gearbox.
- Default operation is gearbox with ISO top flange ready to connect electrical actuator. Pneumatic actuators can be installed directly on the top flange of the valve itself.
- Double Eccentric Butterfly valves are deisgned bi-directional according to EN1074-2. For proper installation, direction arrow on the body should be considered.
- Operation with extended spindle version is also available.
- Balanced positioned lifting holes on the body ease transportation and installation.
- Hydrostatic test pressure for seat: PN x 1.1 , for shell: PN x 1.5 according to EN 12266-1.
