Rotork Gears provides cutting-edge solutions tailored to the specific needs of valve gearboxes and accessories, utilizing an exceptional array of high-quality products. The lineup includes IW cast iron worm gear operators, which come in various configurations such as MOW for modulating applications, MTW for multi-turn (rotary) operations, and specialized versions for the nuclear sector (IWN) as well as ILGD/ILGS actuator override options. These are complemented by smaller manual gearboxes made from 232 aluminum, 300 stainless steel, and AB cast iron.

Additionally, the range features IB and IS cast iron bevel and spur operators available as part of the RAB series, which has received AWWA approval, along with dual shaft models known as DSB. The product lineup also includes cost-effective hand operators, HOB and NTB, while customized gearboxes are available, including WGS subsea versions designed for actuated, manual, and ROV (remotely operated vehicle) valve operations.

The capabilities of Rotork Gears in valve accessories extend to providing mounting kits, spools, pedestals, extension spindles, switchboxes, positioners, handwheels, and chainwheels, all delivered with comprehensive packaging, assembly, and testing services to ensure reliability.

In addition, Rotork Instruments is committed to delivering high performance and precision across its product offerings. This division features leading-edge products such as regulators, boosters, relays, and transducers.

The pneumatic pressure regulators effectively lower an unregulated high input pressure to a controlled, lower output pressure. Their main function is to sustain the desired output pressure, whether under flowing or static conditions.

Electro-pneumatic transducers are designed for accuracy and responsiveness; they are compact, lightweight, and quick to react. Certain models offer analog feedback input, enabling independent control of the process variable or transducer output.

The pneumatic air volume boosters convert low flow control signals into higher regulated flow output pressures. They utilize an unregulated input pressure to maintain a consistent output pressure under both flowing and non-flowing scenarios.

Furthermore, pneumatic relays carry out mathematical operations on one or more input signals, resulting in a single, regulated pneumatic output. This capability ensures precise control and reliability in various applications.
