DYNACTAIR
Output torque [Nm]
at a control pressure of
6 bar
Enclosure
T [°C]
max. 8800
IP65
‐20 to +80
Description:
Single‐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 8800 Nm which are ideal for actuating
quarter‐turn valves. Reset to fail‐safe position is effected by
means of spring assemblies if control air supply is interrupted.
DYNACTAIR is equipped with a visual position indicator and
adjustable travel stops for open/closed position as standard.
Manual override can be provided up to DYNACTAIR 100 on
request. DYNACTAIR 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.

Closing force [N]
max. 6
max. 20,000
Description:
Diaphragm actuator in compact design for mounting on valves
with a linear stem movement (globe, diaphragm and gate
valves). Available in single‐acting spring‐to‐close or spring‐to‐
open design, or double‐acting air‐to‐open/air‐to‐close design;
suitable for mounting limit switches or positioners to suit
customer requirements, factory‐mounted. Settings are adjusted
during factory test run.
Applications:
In building services, industrial plants, power stations; suitable for
abrasive and aggressive products such as service water, waste
water, acids, alkaline solutions, sludges and suspensions.

Closing force [N]
max. 10
max. 250,000
Description:
Piston actuator in heavy‐duty design for industrial use on valves
with a linear stem movement (globe, diaphragm and gate
valves). Mounting flange to DIN/ISO 5210, available in single‐
acting spring‐to‐close or spring‐to‐open design, or double‐acting
air‐to‐open/air‐to‐close design; suitable for mounting limit
switches or positioners to suit customer requirements, factory‐
mounted. Settings are adjusted during factory test run.
Applications:
In building services, industrial plants, power stations, the food
and beverages industries and the chemical industry. The
pneumatic actuators can also be used in potentially explosive
atmospheres.
