Butterfly Valve Gearbox
Viral Industries is a renowned butterfly valve Gearbox manufacturer, supplier & exporter in the USA, Europe, Canada, and Gulf. An industry quickly gaining popularity and recognition is manufacturing butterfly valve gearboxes. These gearboxes are designed with butterfly valves, which control the flow of liquids or gases through a pipe or valve. The butterfly valve has a disc-shaped element attached to a shaft connected to a gearbox. The disc can rotate to open or close the valve based on the gearbox’s rotation direction. Butterfly valve gearboxes are reliable, simple, durable, and commonly used in manual and automated systems. They are increasingly popular in industries such as oil and gas, water treatment, and chemical processing, where precise fluid flow control is critical.

Get the Answers You Need to Move Forward.
Get clear, concise answers to the most common questions about valve gearboxes. Make informed decisions with expert insights and practical guidance.
Manual gearboxes (VW & VWSGA models) use a handwheel for operation, ideal for remote sites or backup control. Actuator-operated models (VWE & VWESGA) integrate with electric, pneumatic, or hydraulic systems for automated, high-torque valve control in industrial processes.
Our gearboxes deliver output torque from 800 Nm up to 500,000 Nm (590–368,800 lbf-ft), covering everything from small water lines to massive pipeline systems in oil, gas, power, and chemical plants.
Yes. All models come with IP65, IP67, or IP68-rated enclosures, offering full protection against dust, water immersion, and corrosion, making them ideal for marine, offshore, desert, or chemical exposure applications.
Absolutely. Models like VWSGA and VWESGA support dual-mode functionality, allowing seamless transition from actuator to handwheel operation during emergencies, ensuring uninterrupted process safety and control.
Yes. We follow ISO 5211 standards for both valve-side and actuator-side flanges (F07 to F60) and support multiple spindle bore shapes, round (with keyways), square, or hexagon, for easy integration with existing butterfly valves worldwide.
