WedgeRock multi-turn bevel gearboxes are designed for heavy-duty valve operation in demanding industrial environments. Suitable for sluice gates, gate valves, globe valves and pinch valves, they provide reliable performance across oil and gas, water treatment, power generation, chemical processing and other industrial applications.

With output torque capabilities of up to 70,000 Nm and thrust capacity of up to 7,200 kN, these gearboxes are engineered to handle demanding operating conditions. Their robust construction is available in ductile iron, carbon steel, stainless steel 316 and low-temperature carbon steel, ensuring flexibility to meet different application requirements.

The gearboxes feature handwheel operation and can be equipped with a motorized output flange in accordance with ISO 5210. A range of optional accessories is available, including dual speed ratios, position indicators, mounting plates, shafts, locking devices, chainwheels and interlocks.

Combining heavy-duty performance, ease of installation and maintenance-free operation, WedgeRock multi-turn bevel gearboxes provide a dependable solution for industrial valve and gate actuation.

WedgeRock planetary gear operators are designed to deliver high efficiency, reliability and long service life in demanding industrial and subsea applications. Unlike conventional worm gear operators, which experience significant friction losses, their innovative rolling gear mechanism maintains multiple teeth in contact and uses self-centering gear carriages to distribute contact stresses evenly, achieving typical efficiencies above 90%.

Available in both manual and motorized configurations, the planetary gear range supports quarter-turn, multi-turn and rising stem applications, for both subsea and topside installations. Its compact, modular design allows customization to meet specific operational requirements, with parallel or perpendicular input shaft configurations and optional self-locking technology.

Combining an efficient drive train with a robust and versatile design, WedgeRock planetary gear operators provide a high-performance solution for valve actuation where efficiency, reliability and optimized operating life are essential.

Maxnovo quarter-turn worm gearboxes are designed for reliable, heavy-duty operation of ball, butterfly and plug valves in demanding industrial environments. Suitable for oil and gas, water treatment, power generation and chemical processing, they provide dependable performance with output torque capabilities of up to 300,000 Nm.

Engineered for durability and ease of operation, these gearboxes feature a robust housing available in ductile iron, carbon steel or stainless steel 316. Optional IP67 and IP68 protection ratings and marinized configurations are available to meet specific environmental and operational requirements.

A range of accessories can be supplied on request, including dual-speed gear units, miter gears, limit switches, locking devices, chainwheels and interlocks, allowing the gearbox to be configured for different application needs.

Combining heavy-duty performance, versatile configuration options and low maintenance requirements, Maxnovo quarter-turn worm gearboxes provide a reliable solution for industrial valve actuation.
