ATM
Series Electronic Valve Actuator |

ATM series electronic
valve actuators are types of multi-turn valve
electric actuators, which are manufactured by
introducing the Limitorque technology from the
US. They are the main body of the Limitorque
electric actuators. ATM series products include
nine specifications such as ATM-01, 03, 00,
1, 2, 3, 4, 5, which the ranges of output torque
are 110-2700 N.m. Parts of the operator of ATM
series products can combine with BA bevel gear
or spur gear reducers, so that they become ATM/BA
combined multi-turn electronic actuators. When
they are combined with HBC worm gear reducers
or with JA planetary reduction gears, they become
combined quarter-turn electronic actuators.
Limitorque valve electric actuators rank as
top grade products and the following are the
distinctive features. |

The
Stroke Control Unitis Feature of ATM series |
» |
The counter gear of the stroke
control unit of ATM series is installed in the
compassion-molded aluminum framework and under
its cover, so the counter gear can be well lubricated
when it is under the condition of accelerating
drive. |
» |
Micro switch is not applied to
the electric actuating device of the stroke
control unit. Its torque control and stroke
control device adopt self-cleaned wide contact
rotary switch, which is made from copper-silver
mixed material, thus it effectively improved
the re liability of electric control, as a result
the product is at the leading level in the country. |
» |
Another Feature of the stroke
control unit of ATM series is that it can provide
multi-contact. The form of the switch contact
can ne arranged according to need, as well as
can be set at normal open or normal close state
at will. |
|
The
Torque Control Units Feature of ATM series: |
» |
As it adopted intermeshing between
the annular rack of the gear pedestal and the
torque switch shaft gear, the conflict
problem between the torque signals, which most
actuators have, can be averted. To some extent,
it improved the reliability of torque control. |
» |
Tailor-made deep groove ball
bearing and check ring used in the hole is employed
so that it can bear the axial thrust force fromthe
worm stem in two ways. Otherwise its dimension
is smaller. |
» |
The disk springs are forged by
adopting oscillating rolling technology, the
components are long-life and more reliable.
The limit sheath set outside the springs can
protect them from ductile deformation. |
» |
For ATM-04, 03, 3, 4, light,
medium or heavy disk springs can be chosen according
to different output torque; for ATM-00-2, two
kinds of disk springs can be chosen, i.e. one
set of light and one heavy springs can be used
together, this combination can effectively enlarge
the adjustable range of the torque and make
the adjustment to the minimum control torque
more convenient |
|
The
Driving Sleeve's Feature of ATM series |
» |
The driving sleeve of ATM series
has its distinctive feature, i.e. the valve
stem nut is input. Due to the nut is emplaced
on theelectric actuator so that it simplified
the construction of flange section of the valve
and reduced customers cost. |
» |
While the electric valve is on
service, it is convenient to lubricate the nut
and the threaded spindle and to change or maintain
the nut. |
» |
The nut is located in the driving
sleeve so that it is easy for axial floating
locating it by employing the disk spring sheath
so ttiat the structure of high temperature and
high speed version can come true. |

The
MDPI Units Feature SMC Series |
» |
Less in volume, easy for mounting,
transmitting with equilibrium, low failure rate. |
» |
With wide range of transmission
ratio, it can satisfy stroke control for values
of various diameters. |
» |
Clear in indication on site,
convenient for adjustment. |
» |
Various types of components for
value position contact sign feedback, satisfying
different control needed. |
» |
ATM series products can be controlled
singly or collectively; and can be controlled
on site or in a control room from distance. |
