Pilot operated check valves allow, if mounted in pairs on the supply ports of a cylinder, to quickly block the movement of the rod in case of a sudden pressure drop.
These one-way blocking valves have a manual override for recharging the cylinder.
This feature is especially valuable during machine set-up or when there is a lack of air problem.
