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.
We offer four main series:
- VGB: Manual/hand-wheel operation
- VGBE: Actuator-driven (electric/pneumatic/hydraulic)
- VGBS: Manual with spur gearbox for ultra-high torque reduction
VGBES: Actuator-driven with spur gearbox for heavy-duty automation
All support torque from 300 Nm to 50,000 Nm and thrust up to 4,800 kN.
Yes. Our VGB/VGBE series are compatible with non-rising stem valves by default. For rising stem applications, the same models deliver precise linear thrust (90–4,800 kN) and feature a top-mounted handwheel with a removable aluminum bronze stem sleeve-ideal for buried or marine installations.
Absolutely. All models 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 ideal for offshore, desert, and chemical exposure applications.
Yes. We follow ISO 5210 standards for both valve-side and actuator-side flanges (F10 to F60). Spindle diameters range from 30mm to 180mm, with bore options in round (keyway), square, or hexagon-ensuring seamless integration with global gate valve systems.
Yes. Standard VGB/VGBE models (e.g., VGB-4000, -6000, 8000) are available with 8:1 ratios, while VGBS/VGBES spur-bevel hybrids offer ratios up to 186:1, dramatically reducing manual effort or actuator load for large-diameter gate valves in water, power, or oil & gas infrastructure.
