DN200 WCB Wafer Triple Offset Butterfly Valve with Worm Gear

Zero Leakage:
The triple offset configuration guarantees a bubble-tight closure, making it perfect for critical services where absolutely no leakage is permissible, such as in gas transmission or chemical manufacturing.

Minimal Friction and Wear:
Thanks to the offset disc arrangement, contact between the disc and seat is significantly reduced during operation, leading to less wear and an extended service lifespan.

Space-Saving and Lightweight:
The wafer-type construction occupies minimal space and weighs less compared to flanged or lugged designs, simplifying installation in confined areas.

Economical Choice:
Wafer-style butterfly valves typically offer a more affordable solution due to their streamlined design and reduced material consumption.

Exceptional Durability:
Constructed from WCB (wrought carbon steel), the valve exhibits superior mechanical robustness and withstands corrosive environments and elevated temperatures up to +427°C when paired with metal seating.

Broad Application Range:
These valves are highly adaptable, capable of handling diverse fluids such as water, oil, gas, steam, and chemicals across sectors including energy, petrochemical, and water management industries.

Reduced Operating Torque:
The triple offset mechanism minimizes the torque required for actuation, enabling the use of smaller and more cost-efficient actuators.

Fire-Resistant Construction:
Designed to comply with fire safety standards like API 607 or API 6FA, the valve is well-suited for environments with high fire risks, such as refineries and chemical plants.

High Performance Under Extreme Conditions:
Featuring metal-to-metal sealing, these valves are engineered to operate reliably under high temperature and high pressure, unlike conventional soft-seated valves.

Simplified Maintenance:
With less sealing surface degradation and robust overall construction, maintenance intervals are extended, and servicing requirements are reduced.
