Valve Operator | KV5 Input Stop
The KV5 Input Stop is designed to provide stop to rotational movement at the input end of high reduction drives such as large valve operating gearbox. This enables the stop to engage where the torque is low and prevent possible damage at the output end where torque is high. This unit is designed to stop an input torque of 500 Nm.
The unit provides a positive stop in both directions the position of each being adjustable to cover a range of 8 to 190 revolutions or with a simple gear change up to 900 revolutions. A repeat accuracy, at input, of 20° is normally achievable on the lower ratio and 40° on the higher ratio.
Input is through a stainless steel shaft. Output is designed to fit an F10 flange and incorporates a splined drive nut, which can be bored and keywayed to suit requirements up to a maximum of 35mm.
Setting of stops is a simple and straight forward process requiring only a few minutes
