The GR Manual Override enables manual operation of actuators when instrument air is unavailable. Designed for single and double-acting actuators, it allows precise control of the valve position. The internal gear system is mounted on ball bearings to minimise operator effort and ensure long service life. It can be integrated with STI actuators or installed directly on a valve without an actuator. Available in various sizes, it includes optional features such as a mechanical chain transmission for remote operation and an adjustable thrust limiter. The robust design ensures reliable performance in standard, offshore, sandstorm, and copper-free environments.
