‐20 to +80
Description:
Double‐acting hydraulic actuator for mounting on quarter‐turn
valves (butterfly valves or ball valves). Actuator flange to ISO
5211. Control pressure up to 120 bar. Mounts on valve stems
with 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 125,000 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 as an
option. The following accessories are available for hydraulic
control: shut‐off valve, hydraulic locking, emergency shutdown
(ESD). Can be combined with all AMTROBOX limit switch boxes.
Applications:
All applications in water, energy and industrial engineering.

‐20 to +80
Description:
Single‐acting hydraulic actuator for mounting on quarter‐turn
valves (butterfly valves or ball valves). Actuator flange to
ISO 5211. Control pressure up to 120 bar. Mounts on valve stems
with 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 4000 Nm which are ideal for actuating
quarter‐turn valves. Reset to fail‐safe position is effected by
means of spring assemblies if control fluid supply is interrupted.
DYNACTO is equipped with a visual position indicator and
adjustable travel stops for open/closed position as standard.
Manual override can be provided up to DYNACTO 100 on
request. The following accessories are available for hydraulic
control: shut‐off valve, hydraulic locking, emergency shutdown
(ESD), hydraulic hand pump. Can be combined with all
AMTROBOX limit switch boxes.
Applications:
All applications in water, energy and industrial engineering.
