Elliott Mfg.

Rigid rod systems are ideal where remote valve operating system paths are straight or nearly straight. The rigid rod can accommodate sharp bends easily with the use of gear boxes or swivel gear joints. In addition to the rigid components, Elliott manufactures numerous adaptors and other fittings so that combination flexible shaft and rigid rod systems can be used together to handle particularly difficult design problems. The quality of our rigid rod systems is equal to that of the flexible shaft components and conform to Naval Sea Systems Command Specifications.

This system is generally great for lower torque requirements. It feature a panel mount options which makes it possible, with an handwheel adapter, to install a lower cost solution. A range of remote operators are available and connection to the valve can be made using a valve coupling or a direct connection to the valve or valve gearbox input shaft. The valve coupling is simply bolted to the existing valve handwheel making installation very simle and engineering free. It is sometimes the case that our SafeOperator FS system is not suitable for very large valves with high input torque. In this case we offer alternate gearbox options.

This system uses relatively small diameter flexible shaft to make system installation and routing extremely FLEXIBLE. Our high quality remote operators can be fitted with a range of handwheel sizes to suit the required input torque. They are easily mounted to any rigid structure. The flexible shaft assembly is extremely hardwearing and can be installed in most environments. It has easy connections to remote operator and the valve gearbox. The valve gearbox features a unique epicycloidal design which has advantages superior to other gearboxes using common involuted tooth gears. Components operate in compression, not in shear. Unlike gear teeth with limited contact points, it has two-thirds of its reduction components in contact at all times. This design enables the gearbox to withstand shock loads exceeding 500% of their ratings, and provide exceptional performance, reliability and long life in the most severe applications. A variety of valve connection options make SafeOperator IG a great fit for any valve. Use our Product calculator to determine which system is right for your valve.
