Design
Double-acting hydraulic actuator for mounting on quarter-turn valves (butterfly valves or ball valves). Top flange to ISO 5211. Control pressure up to 120 bar. Can be mounted on various types of valve stem ends (square end, flat end or key). Force transmission via rack-and-pinion, scotch-yoke or patented Amri yoke kinematics provides output torques of up to 125000 Nm which are ideal for actuating quarter-turn valves. ACTO is equipped with a visual position indicator and adjustable travel stops for open/closed position as standard. Manual override can be provided on request. The following accessoriesare available for hydraulic control: - Shut-off valve - Hydraulic locking - Emergency shutdown (ESD) ACTO can be combined with all AMTROBOX control units.
Applications
All applications in water, energy and industrial engineering.
