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.
A control valve gearbox is designed for precise throttling and modulation, not just on/off operation. Unlike standard quarter-turn or multi-turn gearboxes, it offers fine torque control for applications like flow regulation in oil & gas, power, water treatment, and chemical plants. Our VWM series delivers smooth, repeatable positioning from 600 Nm to 100,000 Nm.
Yes. Our VWM models (VWM-05 to VWM-40) are optimized for manual/hand-wheel operation with low-effort ratios. For automation, we offer top-mounted or side-flange actuator configurations compatible with electric, pneumatic, or hydraulic actuators, ensuring seamless integration into control systems.
Absolutely. The VWM series features self-locking worm gears, precision-machined components, and minimal backlash, enabling accurate valve positioning under varying pressure conditions. This makes them ideal for modulating service in refineries, power plants, and process industries.
Yes. All VWM control gearboxes come with IP65, IP67, or IP68-rated enclosures, offering full protection against dust, water immersion, and corrosion. They operate reliably from –50°C to +150°C, making them suitable for marine, desert, chemical, and buried installations.
We support ISO 5211 flanges (F07 to F60) on both sides for flexible actuator mounting. Spindle bores are available in round (with keyways), square, or hexagon shapes, with diameters from 35mm to 185mm, ensuring compatibility with most control valves worldwide.
