Design Single-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 16000 Nm which are ideal for actuatingquarter-tur
n valves. Reset to fail-safe position is effected by means of a pressurised nitrogen cartridge if control fluid supply is interrupted. ENNACTO is equipped with a visual position indicator and adjustable travel stops for open/closed position as standard. The following accessories are available for hydraulic control: - Hydraulic hand pump ENNACTO can be combined with all AMTROBOX control units. Applications All applications in water, energy and industrial engineering.
