PLDS linear actuators can be supplied with one of four manual overrides, to move the valve by hand when there is no air. Figures from Susin’s PLDS catalogue.
Side-mounted worm gear override, self-locking, with large ratios for low-speed, high-thrust operation. MTG-100 to MTG-1800, matched to each PLDS size.
