Specifications

Rotork Gears has developed a new Dual Speed Input Reducer for reducing the operating time on manual gearbox applications.

The DSIR can be used with any manual gearbox which can be fitted with an input flange of F14 or FA14. It is used to reduce the number of turns required and therefore the operating time for manually operated valves.

The DSIR has two ratios: 1:1 and 4.25:1. Switching between the two ratios is done by simply pushing or pulling on the input shaft. The high 4.25:1 ratio gearing is used for the portion of the valve stroke where the torque requirement is high to initailly open a valve or the last cycles to close it.

During travel the torque usually drops down considerably, the lower 1:1 ratio can be employed to reduce the number of input turns required. Typically this can provide a 70% reduction in the number of turns required and the operating time.
