China DN200 WCB Wafer Triple Offset Butterfly Valve with Worm Gear Manufacturers, Exporter

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.

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.

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

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

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.

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.

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

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.

Featuring metal-to-metal sealing, these valves are engineered to operate reliably under high temperature and high pressure, unlike conventional soft-seated valves.

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