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 16,000 Nm which are ideal for actuating
quarter‐turn 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. Can be combined with all
AMTROBOX limit switch boxes.
Applications:
All applications in water, energy and industrial engineering.

Description:
Double‐acting pneumatic actuator for mounting on quarter‐turn
valves (butterfly valves or ball valves). Actuator flange to
ISO 5211. Control pressure up to 8 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 16,000 Nm which are ideal for actuating
quarter‐turn valves. ACTAIR 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. ACTAIR
can be combined with control unit types AMTROBOX,
AMTRONIC, SMARTRONIC or any other device with a VDI/VDE
3845 interface.
Applications:
All applications in water, energy and industrial engineering.
