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 non-rising valve gearbox controls gate, globe, or check valves where the stem rotates but doesn’t move linearly. Commonly used in water treatment, power plants, oil & gas, and buried installations, it delivers precise multi-turn operation with torque from 300 Nm to 40,000 Nm.
Yes. Our SGB series is designed for manual hand-wheel operation, while the SGBE series integrates seamlessly with electric, pneumatic, or hydraulic actuators. Both support ISO 5210 mounting flanges (F10 to F60) for global compatibility.
Absolutely. The same SGB/SGBE models can handle rising stem applications, delivering thrust from 90 kN up to 4,800 kN. They feature a top-mounted handwheel and removable aluminum bronze stem sleeve, ideal for buried or marine environments.
Yes. All models come with IP65, IP67, or IP68-rated enclosures, offering full protection against dust, water immersion, and corrosion. They operate reliably in extreme temperatures, from – 50°C to +150°C, making them ideal for offshore, desert, and chemical exposure applications.
Yes. We offer customized non-rising valve gearboxes with higher ratios to significantly reduce hand-wheel effort or actuator load, perfect for large-diameter valves in water infrastructure or industrial plants where smooth, low-effort control is essential.
