***0mA Motorized Valve Actuator
1. Summary:
Part-turn electric actuator is used for controlling 0°~**0°
rotation of the valves and other similar products, such as
butterfly valve, ball valve, damper, flapper valve, cock valve etc.
It widely applies to petroleum, chemical, water treatment,
shipping, paper making, power plant, heating, light industry and
other industries. Drived by **0V/**0V/**0VAC power or *4V/**0VDC
power, s ***0mA or ***0VDC control signal, moves valve to the
right position, and achieves to automatic control, maximum output
torque is ***0N·M.(OHQ series have got CE and explosion-proof
certificate)
2. Performance Feature
Shell*-The shell is made of aluminum alloy, with anodic oxidation
treatment and polyester powder coating. It is strong
corrosion-resistant and enclosure IP*7,NEMA 4 and 6, IP*8 and
explosion-proof is optional.
Motor*-Asynchronous motor, small, large torque, and small inertia
force, F-class insulation rating, with thermal protection to avoid
damaging.
Manual Structure*-The design of handwheel is safe, reliable,
labor-saving, small. Declutch to operate by handwheel if without
power, and reset automatically when power on.
Indicator*- Installs indicator in the center axis and adopts convex
mirror design, no cumulate water, more convenient to observe.
Space heater*- It is used for controlling temperature to avoid
condensing internal of housing and keep dry.
Limit switch*- Mechanical, electronic double limit. Mechanical
limit stopper is adjustable, safe and reliable; electronic limit
switch is controlled by cam. Set position accurately and
conveniently, and not affected by excessive handle.
Torque Switch*- (Except QT***5/**8/**0) Providing overload
protection to avoid the damage of valve and electric actuator when
jammed by cutting power automatically.
Self-locking*-Accurate worm and worm gear transfer large torque
efficiently , high efficiency, low noise (max. *0 dB), long life,
with self-locking, prevent inversion, as stable and reliable
transmission parts, no need to refuel.
Anti-off bolt-The bolt attaches to the shell and be not off when
remove the shell.
Installation*- The installation size meets international standard
ISO***1 / DIN***7.
Circuit*-Controlling circuit meets the single-phase or three-phase
power supply standard, circuit layout is reasonable and compact,
terminals meet various of additional functional requirements
effectively.
The display of valve position-During the opening or closing
movement of actuator, the change of valve position on LCD is
displayed with large numbers.
Adjust the phase sequence automatically-Intelligent actuator check
and test the phase sequence for 3 phase power supply automatically,
users no need to consider about the phase sequence.

bolt *-Cover bolts are specially designed to prevent falling down during maintenance or installation *-All external blots are stainless steel for rust prevention |
|
|
Indicator sustained by spring *-Direction of indicator has been set by factory *-If change direction of indicator,just grip the indicator plate to change it *-Spring under the indicator plate sustains the set position unchanged *-No need to loose screw and tight against at all |
|
| Inclined
plane *-For other actuators, it is hard to take off cover because of little tolerance when the interface between cover and body is vertical. *-For OHQ actuators,it is easy to take off cover as small tolerance, ,the design of interface is 3 degree inclined plane |
|
| Torque
switch *-Torque switch protect motorand internal electric components from overheat caused by overload of valve *-If torque works,the actuator stop at once |
|
|
Removable drive sleeve *-Sleeve is removable as different requirement **4 under hungs for tighting or loosing between drive shaft and sleeve *-Easy installation with valve |
|
| Two
slots on window glass *-Two slots on the window covers and convex are convenient for draining and observing,and ensure the well sealing of the cover |
