    ​1. Summary:

    Part-turn electric actuator is used for controlling 0°~360° 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 380V/220V/110VAC power or 24V/110VDC power, inputs 4-20mA or 0-10VDC control signal, moves valve to the right position, and achieves to automatic control, maximum output torque is 6000N·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 IP67, NEMA 4 and 6, IP68 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-005/008/010) 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. 50 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 ISO5211 / DIN3337.

    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.

    6. Standard Parts Structure:

     
      Manual operation (Clutching system)

    --Manual/Auto convert to handle and

    handwheel used for emergency manual

    operation

    --Powered, handle will automatically

    reset to auto operation
      Cam and limit switch

    --Tighten with two screws and simple

    setting

    --Each cam can be setseparately

    --Once set, each cam will be on the

    position forever
      Space heater

    --7-10W, ceramic housing with thermostat

    to prevent overheat comparing with set

    temperature

    --Without risk of electricity leakage
      Terminal block

    --Enough terminal for customer's

    convenience(Max 22 points)

    --Proven reliability and tight wiring

    connection

    --Terminal length:8-9mm/(2.5mm2)

    --Terminal dimension:10×22×32mm
      Anti-off 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
