Explosion-Proof Electric Actuator, Corrosion Resistance 
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 OHQ-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
--Powered,handle will automatically
reset to auto operation

Cam and limit switch
--Tighten with two screws and simple
--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
--Without risk of electricity leakage

Terminal block
--Enough terminal for customer's
convenience(Max 22 points)
--Proven reliability and tight wiring
--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
--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 CHQ 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

Removable drive sleeve
--Sleeve is removable as different
--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
